- Muslim Agricultural Revolution
The
Islamic Golden Age from the8th century to the13th century witnessed a fundamental transformation inagriculture known as the Arab Agricultural Revolution, Medieval Green Revolution, [A. M. Watson (1981), "A Medieval Green Revolution: New Crops and Farming Techniques in the Early Islamic World", in "The Islamic Middle East, 700-1900: Studies in Economic and Social History"] or Muslim Agricultural Revolution.Zohor Idrisi (2005), [http://www.muslimheritage.com/uploads/AgricultureRevolution2.pdf The Muslim Agricultural Revolution and its influence on Europe] , FSTC] Theglobal economy established byArab and otherMuslim traders across theOld World , enabled thediffusion of many crops andfarming techniques among different parts of the Islamic world, as well as the adaptation of crops and techniques from and to regions beyond the Islamic world. Crops fromAfrica such assorghum , crops fromChina such ascitrus fruit s, and numerous crops fromIndia such asmango s,rice , and especiallycotton andsugar cane , were distributed throughout Islamic lands, which previously had not grown these crops. Some writers have referred to the diffusion of numerous crops during this period as theGlobalization of crops. [ [http://www.muslimheritage.com/topics/default.cfm?ArticleID=229 The Globalisation of Crops] , FSTC] These introductions, along with an increasedmechanization of agriculture (see Industrial growth below), led to major changes ineconomy ,population distribution ,vegetation cover, [Andrew M.

Watson (1974), "The Arab Agricultural Revolution and Its Diffusion, 700–1100", "The Journal of Economic History" 34 (1), pp. 8–35.]Age of discovery
The earliest forms of
globalization began emerging during theIslamic Empire and the Islamic Golden Age, when theknowledge ,trade and economies from many previously isolated regions andcivilization s began integrating due to contacts withMuslim explorer s,sailor s, scholars, traders, andtravel ers. Some have called this period the "Pax Islamica" or "Afro-Asiaticage of discovery ", in reference to the MuslimSouthwest Asia n andNorth Africa n traders and explorers who travelled most of theOld World , and established an earlyglobal economy across most ofAsia andAfrica and much ofEurope , with their tradenetwork s extending from theAtlantic Ocean andMediterranean Sea in the west to theIndian Ocean andChina Sea in the east.Subhi Y. Labib (1969), "Capitalism in Medieval Islam", "The Journal of Economic History" 29 (1), p. 79-96.] This helped establish theIslamic Empire (including the Rashidun,Umayyad ,Abbasid andFatimid caliphate s) as the world's leading extensive economic power throughout the 7th-13th centuries.John M. Hobson (2004), "The Eastern Origins of Western Civilisation", p. 29-30,Cambridge University Press , ISBN 0521547245.] Several contemporary medieval Arabic reports also suggest that Muslim explorers fromal-Andalus and theMaghreb may have travelled in expeditions across theAtlantic Ocean , possibly even to theAmericas , between the 9th and 14th centuries. [S. A. H. Ahsani (July 1984). "Muslims in Latin America: a survey", "Journal of Muslim Minority Affairs" 5 (2), p. 454-463.]Agricultural innovations
Muslims introduced
cash crop ping and the moderncrop rotation system where land was cropped four or more times in a two-year period. Winter crops were followed by summer ones, and in some cases there was in between. In areas whereplant s of shorter growing season were used, such asspinach andeggplant s, the land could be cropped three or more times a year. In parts ofYemen ,wheat yield ed twoharvest s a year on the same land, as didrice in Iraq. Muslims developed a scientific approach based on three major elements; sophisticated systems of crop rotation, highly developedirrigation techniques, and the introduction of a large variety ofcrops which were studied and catalogued according to theseason , type ofland and amount ofwater they require. Numerousencyclopaedia s onfarming andbotany were produced, with highly accurateprecision and details.Al-Hassani, Woodcock and Saoud (2007), "Muslim heritage in Our World", FSTC publishing, 2nd Edition, pp. 102–23.] The earliestcookbook s onArab cuisine were also written, such as the "Kitab al-Tabikh " ("The Book of Dishes") of Ibn Sayyiir al-Warraq (10th century) and the "Kitab al-Tabikh" ofMuhammad bin Hasan al-Baghdadi (1226). [David Waines (1987), "Cereals, Bread and Society: An Essay on the Staff of Life in Medieval Iraq", "Journal of the Economic and Social History of the Orient" 30 (3), pp. 255–85 [276, 278, 282] .]Advanced agricultural systems
As early as the 9th century, an essentially modern agricultural system became central to economic life and organization in the Arab caliphates, replacing the largely export driven Roman model. The great cities of the Near East, North Africa and Moorish Spain were supported by elaborate agricultural systems which included extensive irrigation based on knowledge of
hydraulic andhydrostatic principles, some of which were continued from Roman times. In later centuries, Persian Muslims began to function as a conduit, transmitting cultural elements, including advanced agricultural techniques, into Turkic lands and western India. The Muslims introduced what was to become an agricultural revolution based on four key areas:* Development of a sophisticated system of
irrigation usingmachine s such asnoria s,water mill s, water raising machines,dam s andreservoir s. With such technology they managed to greatly expand the exploitable land area.
* The adoption of a scientific approach to farming enabled them to improve farming techniques derived from the collection and collation of relevant information throughout the whole of the known world. Farming manuals were produced in every corner of the Muslim world detailing where, when and how to plant and grow various crops. Advanced scientific techniques allowed leaders likeIbn al-Baitar to introduce new crops and breeds and strains of livestock into areas where they were previously unknown.
* Incentives based on a new approach toland ownership and labourers' rights, combining the recognition of private ownership and the rewarding of cultivators with a harvest share commensurate with their efforts. Their counterparts in Europe struggled under a feudal system in which they were almost slaves (serfs ) with little hope of improving their lot by hard work.
* The introduction of new crops transforming private farming into a new global industry exported everywhere, including Europe, where farming was mostly restricted to wheat strains obtained much earlier via central Asia. Spain received what she in turn transmitted to the rest of Europe; many agricultural and fruit-growing processes, together with many new plants, fruit and vegetables. These new crops included sugar cane, rice, citrus fruit, apricots, cotton, artichokes, aubergines, and saffron. Others, previously known, were further developed. Muslims also brought to that country lemons, oranges, cotton, almonds, figs and sub-tropical crops such as bananas and sugar cane. Several were later exported from Spanish coastal areas to the Spanish colonies in the New World. Also transmitted via Muslim influence, a silk industry flourished, flax was cultivated and linen exported, andesparto grass, which grew wild in the more arid parts, was collected and turned into various articles.Economic and social reforms
The
Caliphate understood that realincentive s were needed to increaseproductivity andwealth , thus enhancingtax revenue s, hence they introduced a social transformation through the changedownership of land, where any individual of anygender [Maya Shatzmiller, p. 263.] or anyethnic orreligious background had the right tobuy ,sell ,mortgage andinherit land forfarming or any other purposes. They also introduced the signing of acontract for every majorfinancial transaction concerningagriculture ,industry ,commerce , andemployment . Copies of the contract was usually kept by both parties involved.The two types of
economic system s that prompted agricultural development in the Islamic world were eitherpolitic ally-driven, by the conscious decisions of the central authority to develop under-exploited lands; ormarket -driven, involving the spread ofadvice ,education , and freeseed s, and the introduction of high valuecrops oranimal s to areas where they were previously unknown. These led to increasedsubsistence , a high level ofeconomic security that ensuredwealth for all citizens, and a higherquality of life due to the introduction ofartichoke s,spinach ,aubergine s,carrot s,sugar cane , and various exoticplant s;vegetable s being available all year round without the need to dry them for winter;citrus andolive plantations becoming a common sight,market garden s andorchard s springing up in every Muslimcity ; intensecrop ping and the technique of intensiveirrigation agriculture with landfertility replacement; a major increase inanimal husbandry ; higher quality ofwool and otherclothing materials; and the introduction ofselective breeding of animals from different parts of theOld World resulting in improvedhorse stocks and the best load-carryingcamel s.ugar industry
During the Muslim Agricultural Revolution,
sugar production was refined and transformed into a large-scaleindustry by theArab s. The Arabs andBerbers diffused sugar throughout theArab Empire from the 8th century.Other innovations
Many other agricultural innovations were introduced by Muslim farmers and engineers, such as new forms of
land tenure , improvements inirrigation , a variety of sophisticated irrigation methods, [Elias H. Tuma (1987), "Agricultural Innovation in the Early Islamic World: The Diffusion of Crops and Farming Techniques, 700–1100" by Andrew M. Watson", "The Journal of Economic History" 47 (2), pp. 543–4.] the introduction offertilizer s and widespread artificial irrigation systems, the development ofgravity -flow irrigation systems fromriver s and springs, the first uses ofnoria andchain pump s for irrigation purposes, the establishment of thesugar cane industry in theMediterranean andexperiment ation insugar cultivation, [J. H. Galloway (1977), "The Mediterranean Sugar Industry", "Geographical Review" 67 (2), pp. 177–94.] numerous advances in industrialmill ing and water-raising machines (see Industrial growth below), and many other improvements and innovations.Agricultural sciences
During the Muslim Agricultural Revolution, Muslim scientists laid the foundations of
agricultural science , which included significant advances in the fields ofagronomy , astronomy,botany ,earth science ,environmental philosophy , andenvironmental science . In particular, theexperiment alscientific method was introduced into the field in the 13th century by the Andalusian-Arab botanist Abu al-Abbas al-Nabati, the teacher ofIbn al-Baitar . Al-Nabati introducedempirical techniques in the testing, description and identification of numerousmateria medica , and he separated unverified reports from those supported by actual tests and observations.

Ibn Wahshiyya 's "Nabatean Agriculture", which also dealt with the related field of botany and was also an earlycookbook . The early Arab lexicographs were the first known works to separate the two disciplines of agriculture and botany, though both were considered part of the medical sciences due to agriculture's primary role being to feed and botany's primary role being to heal. The agricultural sciences were known by the Arabic term "filaha", which had a dual-meaning, to both care for the Earth and to take care of plants. Many of the early Islamic authors on botany were oftenphilologists , due to their role in the translation of ancient scientific texts. [citation|last=Fahd|first=Toufic|contribution=Botany and agriculture|pages=813, in Harv|Morelon|Rashed|1996|pp=813-52] This was also the case with early Arabiczoology , like withal-Jahiz for example.Al-Asma'i was the earliest known Arab biologist, botanist and zoologist; his works include the "Book of Distinction", "Book of the Wild Animals", "Book of the Horse", and "Book of the Sheep".Agronomy
Muslim agriculturists demonstrated advanced agronomic, agrotechnical and
economic knowledge in areas such asmeteorology ,climatology ,hydrology ,soil occupation, and theeconomy andmanagement of agriculturalenterprise s. They also demonstrated agricultural knowledge in areas such aspedology , agriculturalecology ,irrigation , preparation of soil,planting , spreading ofmanure , killingherb s,sowing , cuttingtree s,grafting ,pruning vine ,prophylaxis ,phytotherapy , the care and improvement ofmicrobiological culture s andplant s, and theharvest and storage ofcrops . [Toufic Fahd (1996), "Botany and agriculture", in Roshdi Rashed, ed., "Encyclopedia of the History of Arabic Science ", Vol. 3, pp. 813–52 [849] .Routledge , London and New York.]Ibn Wahshiyya 's "Nabatean Agriculture" was an early Arabic work on agronomy and agriculture. The following eight chapters of the book are dedicated towater in the context of agriculture: [citation|last=Fahd|first=Toufic|contribution=Botany and agriculture|pages=841, in Harv|Morelon|Rashed|1996|pp=813-52]#Research of water and related technical knowledge
#Diggingwell s and increasing their flow using proven artifices and techniques
#Thedrilling of wells
#Artifice s used to increase water in a well
#Making water rise up a very deep well
#Augment ing the quantity of water in wells and sources
#Modifying and improving the taste of water
#"On the difference in nature and action of the water according to its position" close of far away "with regard to theecliptic "The "Nabatean Agriculture" then goes on to discuss a number of other complex issues on agriculture, including the management of an agricultural
enterprise and the duties of the owner regarding his enterprise and workers; theofficial ("wakil") in charge of the management of the enterprise, his obligation towards thefarmer s, and applying the instructions he receives from his boss; theweather forecasting of atmospheric changes and signs from the planetary astral alterations; signs of rain based on observation of thelunar phase s, nature of thunder and lightning, direction ofsunrise , behaviour of certain plants and animals, and weather forecasts based on the movement ofwind s; the recognition ofplant tissue culture s which succeed in certain years; a list of work to be done in each month of year; the position of the moon relative to the Earth; the required knowledge of a farmer and the owner of an agricultural enterprise;pollen izedair and winds; and formation of winds andvapour s. [citation|last=Fahd|first=Toufic|contribution=Botany and agriculture|pages=842, in Harv|Morelon|Rashed|1996|pp=813-52]Other agricultural topics discussed in the "Nabatean Agriculture" include the causes of the corruption of plants and of torrential rain; the nature of
soil s and their different flavours; themanure ; how to get rid of badherb s and how to cut plants which need to be cut; and a number of other agricultural topics. [citation|last=Fahd|first=Toufic|contribution=Botany and agriculture|pages=842, in Harv|Morelon|Rashed|1996|pp=813-52]In 12th century
al-Andalus ,Ibn al-'Awwam al-Ishbili wrote the "Kitab al-Filaha" which synthesized his own agricultural knowledge with that of the "Nabatean Agriculture" and his other Arabic predecessors. This work also described 585microbiological culture s, 55 of which concernfruit tree s. This work was influential in Europe after it was translated into Spanish by Banqueri inMadrid in 1801 and into French by Clement-Mullet inParis in 1864. [citation|last=Fahd|first=Toufic|contribution=Botany and agriculture|pages=848-9, in Harv|Morelon|Rashed|1996|pp=813-52]Astronomy and meteorology
Another innovation during this period was the application of astronomy to agriculture and botany. As
weather forecasting predictions and the measurement oftime and the onset ofseason s became more precise and reliable, farmers became informed of these advances and often employed them in agriculture. They also benefited from the compilation ofcalendar s with information on when to plant each type of crop, when to graft trees, when and how tofertilize crops, when toharvest , and what to eat and what to avoid at each time of year. These advances made it possible for farmers to plan the growth of each of their crops for specificmarket s and at specific times of the year.Parts of
al-Dinawari 's "Book of Plants" deals with the applications of astronomy andmeteorology to agriculture. It describes the astronomical and meteorological character of the sky, theplanet s andconstellation s, thesun andmoon , thelunar phase s indicatingseason s andrain , the "anwa" (heavenly bodies of rain), and atmospheric phenomena such as winds, thunder, lightning, snow, floods, valleys, rivers, lakes, wells and other sources of water.Botany
Muslims developed a scientific approach to
botany and agriculture based on three major elements; sophisticated systems ofcrop rotation , highly developedirrigation techniques, and the introduction of a large variety ofcrops which were studied and catalogued according to theseason , type ofland and amount ofwater they require. Numerousencyclopaedia s onbotany were produced, with highly accurateprecision and details.The 9th century botanist
al-Dinawari is considered the founder of Arabic botany. He wrote a botanical encyclopedia entitled "Kitab al-Nabat" ("Book of Plants"), which consisted of six volumes. Only the third and fifth volumes have survived, though the sixth volume has partly been reconstructed based on citations from later works. In the surviving portions of his works, 637 plants are described from the letters "sin" to "ya". He also discussesplant evolution from its birth to its death, describing the phases ofplant growth and the production of flowers and fruit.citation|last=Fahd|first=Toufic|contribution=Botany and agriculture|pages=815, in Harv|Morelon|Rashed|1996|pp=813-52]In the early 13th century,
Ibn al-Baitar published the "Kitab al-Jami fi al-Adwiya al-Mufrada", which is considered one of the greatest botanical compilations and pharmaceutical encyclopedias, and was a botanical authority for centuries. It contains details on at least 1,400 differentplant s,food s, anddrug s, 300 of which were his own original discoveries. The "Kitab al-Jami fi al-Adwiya al-Mufrada" was also influential inEurope after it was translated intoLatin in 1758,Russell McNeil, [http://www.mala.bc.ca/~mcneil/baitart.htm Ibn al-Baitar] ,Malaspina University-College .] where it was being used up until the early 19th century.Diane Boulanger (2002), "The Islamic Contribution to Science, Mathematics and Technology", "OISE Papers", in "STSE Education", Vol. 3.]Earth science
Muslim scientists made a number of contributions to the
Earth science s.Alkindus introducedexperiment ation into the Earth sciences.Plinio Prioreschi, "Al-Kindi, A Precursor Of The Scientific Revolution", "Journal of the International Society for the History of Islamic Medicine", 2002 (2): 17-19.]Parts of
al-Dinawari 's "Book of Plants" deals with the Earth sciences in the context of agriculture. He considers the Earth, stone and sands, and describes different types ofground , indicating which types are more convenient for plants and the qualities and properties of good ground.Biruni is considered the father ofgeodesy for his important contributions to the field,Akbar S. Ahmed (1984). "Al-Beruni: The First Anthropologist", "RAIN" 60, p. 9-10.] [H. Mowlana (2001). "Information in the Arab World", "Cooperation South Journal" 1.] along with his significant contributions togeography andgeology .Among his writings on geology, Biruni wrote the following on the
geology of India :John J. O'Connor and Edmund F. Robertson write in the "
MacTutor History of Mathematics archive ":In
geology ,Avicenna hypothesized on two causes ofmountain s in "The Book of Healing ". Incartography , thePiri Reis map drawn by the Ottoman cartographerPiri Reis in 1513, was one of the earliestworld map s to include theAmericas , and perhaps the first to includeAntarctica . His map of the world was considered the most accurate in the 16th century.Environmental philosophy
Perhaps due to resource scarcity in most Islamic nations, there was an emphasis on limited (and some claim also sustainable) use of
natural capital , i.e. producing land. Traditions ofharam andhima and earlyurban planning were expressions of strong social obligations to stay withincarrying capacity and to preserve thenatural environment as an obligation ofkhalifa or "stewardship". [S. Nomanul Haq, "Islam", in Dale Jamieson (2001), "A Companion to Environmental Philosophy", pp. 111-129,Blackwell Publishing , ISBN 140510659X.]Muhammad is considered a pioneer ofenvironmentalism for his teachings onenvironmental preservation . Hishadith s onagriculture andenvironmental philosophy were compiled in the "Book of Agriculture" of the "Sahih Bukhari ", which included the following saying: [S. Nomanul Haq, "Islam", in Dale Jamieson (2001), "A Companion to Environmental Philosophy", pp. 111-129 [119-129] ,Blackwell Publishing , ISBN 140510659X.]Several such statements concerning the environment are also found in the
Qur'an , such as the following: [S. Nomanul Haq, "Islam", in Dale Jamieson (2001), "A Companion to Environmental Philosophy", pp. 111-129 [111-119] ,Blackwell Publishing , ISBN 140510659X.]Environmental science
The earliest known treatises dealing with
environmentalism andenvironmental science , especiallypollution , were Arabic medical treatises written byal-Kindi ,Qusta ibn Luqa ,al-Razi ,Ibn Al-Jazzar ,al-Tamimi ,al-Masihi ,Avicenna ,Ali ibn Ridwan , Ibn Jumay,Isaac Israeli ben Solomon ,Abd-el-latif , Ibn al-Quff, andIbn al-Nafis . Their works covered a number of subjects related to pollution such asair pollution ,water pollution ,soil contamination ,municipal solid waste mishandling, andenvironmental impact assessment s of certain localities. [L. Gari (2002), "Arabic Treatises on Environmental Pollution up to the End of the Thirteenth Century", "Environment and History" 8 (4), pp. 475-488.] Cordoba,al-Andalus also had the firstwaste container s andwaste disposal facilities forlitter collection.

:"Further information: and
Islamic medicine "In the
zoology field ofbiology , Muslim biologists developed theories onevolution andnatural selection which were widely taught in medieval Islamic schools.John William Draper , a contemporary ofCharles Darwin , considered the "Mohammedan theory of evolution" to be developed "much farther than we are disposed to do, extending them even to inorganic ormineral things." According toal-Khazini , ideas on evolution were widespread among "common people" in the Islamic world by the 12th century. [John William Draper (1878). "History of the Conflict Between Religion and Science", p. 154-155, 237. ISBN 1603030964.]The first Muslim biologist to develop a theory on evolution was
al-Jahiz (781-869). He wrote on the effects of the environment on the likelihood of an animal to survive, and he first described the struggle for existence and an early form ofnatural selection . [Conway Zirkle (1941). Natural Selection before the "Origin of Species", "Proceedings of the American Philosophical Society" 84 (1), p. 71-123.] [Mehmet Bayrakdar (Third Quarter, 1983). "Al-Jahiz And the Rise of Biological Evolutionism", "The Islamic Quarterly".London .] Al-Jahiz was also the first to discussfood chain s, [Frank N. Egerton, "A History of the Ecological Sciences, Part 6: Arabic Language Science - Origins and Zoological", "Bulletin of the Ecological Society of America", April 2002: 142-146 [143] ] and was also an early adherent ofenvironmental determinism , arguing that the environment can determine the physical characteristics of the inhabitants of a certain community and that the origins of differenthuman skin color s is the result of the environment. [Lawrence I. Conrad (1982), "Taun and Waba: Conceptions of Plague and Pestilence in Early Islam", "Journal of the Economic and Social History of the Orient" 25 (3), pp. 268-307 [278] .]Ibn al-Haytham wrote a book in which he argued forevolutionism (although not natural selection), and numerous other Islamic scholars and scientists, such asIbn Miskawayh , theBrethren of Purity ,al-Khazini ,Abū Rayhān al-Bīrūnī ,Nasir al-Din Tusi , andIbn Khaldun , discussed and developed these ideas. Translated into Latin, these works began to appear in the West after theRenaissance and appear to have had an impact on Western science.Ibn Miskawayh 's "al-Fawz al-Asghar" and theBrethren of Purity 's "Encyclopedia of the Brethren of Purity " ("The Epistles of Ikhwan al-Safa") expressed evolutionary ideas on how species evolved frommatter , intovapor , and thenwater , thenmineral s, thenplant s, thenanimal s, thenape s, and thenhuman s. These works were known in Europe and likely had an influence onDarwinism .Muhammad Hamidullah and Afzal Iqbal (1993), "The Emergence of Islam: Lectures on the Development of Islamic World-view, Intellectual Tradition and Polity", p. 143-144. Islamic Research Institute, Islamabad.]Capitalist market economy
Capitalism developed much earlier in Islamic regions than in theOccident . Subhi Y. Labib argues the reason for this was the growing trade economy of the Muslim world, and security from Barbarian invasions. The firstmarket economy and earliest forms ofmerchant capitalism took root between the 8th–12th centuries in the Caliphate, which are referred to as "Islamic capitalism". [Subhi Y. Labib (1969), "Capitalism in Medieval Islam", "The Journal of Economic History" 29 (1), pp. 79–96 [81, 83, 85, 90, 93, 96] .] A vigorousmonetary economy was created on the basis of the expanding levels of circulation of a stable high-valuecurrency (thedinar ) and the integration ofmonetary areas that were previously independent. Innovative newbusiness techniques and forms ofbusiness organisation were introduced byeconomist s,merchant s and traders during this time. Such innovations included the earliest trading companies,big business es,contract s,bills of exchange , long-distanceinternational trade , the first forms ofpartnership ("mufawada") such aslimited partnership s ("mudaraba"), and the earliest forms of credit,debt ,profit ,loss , capital ("al-mal"),capital accumulation ("nama al-mal"),circulating capital ,capital expenditure ,revenue ,cheque s,promissory note s, [Robert Sabatino Lopez, Irving Woodworth Raymond, Olivia Remie Constable (2001), "Medieval Trade in the Mediterranean World: Illustrative Documents",Columbia University Press , ISBN 0231123574.]trusts andcharitable trust s (see "Waqf "),startup companies , [Timur Kuran (2005), "The Absence of the Corporation in Islamic Law: Origins and Persistence", "American Journal of Comparative Law" 53, pp. 785–834 [798–9] .]savings account s,transactional account s,pawn ing,loan ing,exchange rate s,bank ers,money changer s,ledger s,deposit s, assignments, thedouble-entry bookkeeping system , [Subhi Y.

[Ray Spier (2002), "The history of the peer-review process", "Trends in Biotechnology" 20 (8), p. 357-358 [357] .]Organization alenterprise s similar tocorporation s independent from thestate also existed in the medieval Islamic world, while the agency andaval institutions (see "Hawala ") was also introduced. [Said Amir Arjomand (1999), "The Law, Agency, and Policy in Medieval Islamic Society: Development of the Institutions of Learning from the Tenth to the Fifteenth Century", "Comparative Studies in Society and History" 41, pp. 263–93.Cambridge University Press .] [Samir Amin (1978), "The Arab Nation: Some Conclusions and Problems", "MERIP Reports" 68, pp. 3–14 [8, 13] .] Many of these early capitalist concepts were adopted and further advanced inmedieval Europe from the 13th century onwards.Jairus Banaji (2007), "Islam, the Mediterranean and the rise of capitalism", "Journal Historical Materialism" 15 (1), pp. 47–74,Brill Publishers .]The systems of
contract relied upon bymerchant s was very effective. Merchants would buy and sell on commission, with moneyloan ed to them by wealthyinvestor s, or a jointinvestment of several merchants, who were often Muslim, Christian and Jewish. Recently, a collection of documents was found in anEgypt iansynagogue shedding a very detailed and human light on the life of medieval Middle Eastern merchants. Businesspartnership s would be made for many commercial ventures, and bonds ofkinship enabled tradenetwork s to form over huge distances.Crops
Hundreds of
crops were diffused throughout the Islamic world and beyond as a result of the Muslim Agricultural Revolution, some of which includeartichoke s,banana s,coconut palm s,colocasia ,cotton ,eggplant s, hardwheat ,lemon s, limes,mango s,plantain s,rice ,sorghum ,sour orange s,spinach ,sugar cane , andwatermelon s, [Andrew M. Watson (1974), "The Arab Agricultural Revolution and Its Diffusion, 700–1100", "The Journal of Economic History" 34 (1), pp. 8–35 [9] .] among hundreds of other crops.Industrial growth
Muslim engineers in the Islamic world were responsible for numerous innovative industrial uses of
hydropower , early industrial uses oftidal power ,wind power , andfossil fuel s such aspetroleum , and the earliest largefactory complexes ("tiraz" in Arabic). [Maya Shatzmiller, p. 36.] The industrial uses ofwatermill s in the Islamic world date back to the 7th century, while horizontal-wheeled and vertical-wheeled water mills were both in widespread use since at least the 9th century. A variety of industrialmill s were first invented in the Islamic world, includingfulling mills,gristmill s,huller s,paper mill s,sawmill s, shipmills,stamp mill s,steel mill s, sugar mills,tide mill s, andwindmill s. By the 11th century, every province throughout the Islamic world had these industrial mills in operation, fromal-Andalus andNorth Africa to theMiddle East andCentral Asia .Adam Robert Lucas (2005), "Industrial Milling in the Ancient and Medieval Worlds: A Survey of the Evidence for an Industrial Revolution in Medieval Europe", "Technology and Culture" 46 (1), pp. 1–30 [10] .] Muslim engineers also inventedcrankshaft s andwater turbine s, first employedgear s in mills and water-raisingmachine s, and pioneered the use ofdam s as a source of water power, used to provide additional power to watermills and water-raising machines. Such advances made it possible for many industrial tasks that were previously driven bymanual labour inancient times to be mechanized and driven bymachine ry instead in the medieval Islamic world. The transfer of these technologies to medieval Europe later laid the foundations for theIndustrial Revolution in 18th century Europe.Many industries were generated due to the Muslim Agricultural Revolution, including the earliest industries for
agribusiness , astronomical instruments,ceramic s, chemicals,distillation technologies,clock s,glass , mechanicalhydropower ed andwind power edmachine ry,mat ting,mosaic s, pulp and paper,perfume ry, petroleum, pharmaceuticals,rope -making,shipping ,shipbuilding ,silk ,sugar , textiles, water,weapon s, and themining ofmineral s such assulfur ,ammonia ,lead andiron . The first largefactory complexes ("tiraz") were built for many of these industries. Knowledge of these industries were later transmitted tomedieval Europe , especially during theLatin translations of the 12th century , as well as before and after. For example, the first glass factories in Europe were founded in the 11th century byEgypt ian craftsmen inGreece . [Ahmad Y Hassan , [http://www.history-science-technology.com/Articles/articles%207.htm Transfer Of Islamic Technology To The West, Part 1: Avenues Of Technology Transfer] ] Theagricultural andhandicraft industries also experienced high levels of growth during this period.Chemical industries
The
chemical industry andpetroleum industry were established in the 8th century, when themineral acid s (such assulfuric acid ) were first produced throughdry distillation , and when thestreet s ofBaghdad were paved withtar , derived frompetroleum throughdestructive distillation . In the 9th century,oil field s were exploited in the area around modernBaku ,Azerbaijan , to producenaphtha . These fields were described byMasudi in the 10th century, and byMarco Polo in the 13th century, who described the output of thoseoil well s as hundreds of shiploads. [K. Ajram (1992). "Miracle of Islamic Science", Appendix B. Knowledge House Publishers. ISBN 0911119434.] Petroleum was distilled byal-Razi in the 9th century, producing chemicals such askerosene in thealembic , which he used to inventkerosene lamp s for use in theoil lamp industry. [Zayn Bilkadi (University of California, Berkeley ), "The Oil Weapons", "Saudi Aramco World ", January–February 1995, pp. 20–7.]An early industrial use of
steam power dates back to theperfume ry industry established by Muslim chemists such asGeber ,al-Razi , andAvicenna , who pioneered and perfected the extraction offragrance s andessential oil s throughsteam distillation , introduced new rawingredient s, and developed cheap methods for themass production of perfumery andincense s. Both the raw ingredients anddistillation technology significantly influenced Western perfumery. Muslim traders had wide access to a variety of differentspice s,herb s, and other fragrance materials. In addition to trading them, many of these exotic materials were cultivated by the Muslims such that they could be successfully grown outside of their native climates. Two examples of this includejasmine , which is native toSouth Asia andSoutheast Asia , and variouscitrus fruit s native toEast Asia . Both of these ingredients are still highly important in modern perfumery.The first industrial complex for
glass andpottery production was built inAr-Raqqah ,Syria , in the 8th century. Extensive experimentation was carried out at the complex, which was twokilometre s in length, and a variety of innovative high-purity glass were developed there.

Muslim engineers pioneered two solutions to achieve the maximum output from a
water mill . The first solution was to mount them topier s ofbridge s to take advantage of the increased flow. The second solution was the shipmill, a unique type ofwater mill powered bywater wheel s mounted on the sides ofship s moored inmidstream . This was first employed along theTigris andEuphrates rivers in 10th centuryIraq , where large shipmills made ofteak andiron could produce 10ton s of flour from corn every day for thegranary inBaghdad .Donald Routledge Hill , "Mechanical Engineering in the Medieval Near East", "Scientific American", May 1991, pp. 64–9. (cf. Donald Routledge Hill , [http://home.swipnet.se/islam/articles/HistoryofSciences.htm Mechanical Engineering] )] Industrial water mills were also employed in the first largefactory complexes built inal-Andalus between the 11th and 13th centuries. Fulling mills, paper mills, steel mills, and other mills, spread from Islamic Spain to Christian Spain by the 12th century. [Adam Robert Lucas (2005), "Industrial Milling in the Ancient and Medieval Worlds: A Survey of the Evidence for an Industrial Revolution in Medieval Europe", "Technology and Culture" 46 (1), pp. 1–30 [11] .]Windmill s were first built inSistan ,Afghanistan , from the7th century . These were verticalaxle windmills, which had long verticaldriveshaft s with rectangle shapedblade s. [Ahmad Y Hassan ,Donald Routledge Hill (1986). "Islamic Technology: An illustrated history", p. 54.Cambridge University Press . ISBN 0-521-42239-6.] The first windmill was built by theRashidun caliph Umar (634–44). [Dietrich Lohrmann (1995). "Von der östlichen zur westlichen Windmühle", "Archiv für Kulturgeschichte" 77 (1), pp. 1–30 (8).] Made of six to twelvesail s covered inreed mat ting orcloth material, these windmills were used to grindcorn and draw upwater , and were used in thegristmill ing and sugarcane industries.Donald Routledge Hill , "Mechanical Engineering in the Medieval Near East", "Scientific American", May 1991, pp. 64–9. (cf. Donald Routledge Hill , [http://home.swipnet.se/islam/articles/HistoryofSciences.htm Mechanical Engineering] )]After
paper was introduced into the Islamic world by Chinese prisoners following theBattle of Talas , Muslims made significant improvements topapermaking and built the firstpaper mill s inBaghdad ,Iraq , as early as794 . Papermaking was transformed from an art into a major industry as a result. [ [http://www.muslimheritage.com/topics/default.cfm?ArticleID=329 The Beginning of the Paper Industry] , Foundation for Science Technology and Civilisation.] This allowed themanufacturing of paper in the Islamic world to be performed using water power rather than manual labour. The firstfulling mills were later invented in the 10th century, followed by the firststamp mill s andsteel mill s in the 11th century. [Adam Robert Lucas (2005), "Industrial Milling in the Ancient and Medieval Worlds: A Survey of the Evidence for an Industrial Revolution in Medieval Europe", "Technology and Culture" 46 (1), pp. 1–30 [10–1] .]The first
gristmill s were invented by Muslim engineers in the Islamic world, and were used for grindingcorn and otherseed s to producemeal s, and many other industrial uses such asfulling cloth, husking rice,papermaking , pulping sugarcane, and crushing metalic ores before extraction. Gristmills in the Islamic world were often made from bothwatermill s andwindmill s. In order to adaptwater wheel s for gristmilling purposes,cam s were used for raising and releasingtrip hammer s to fall on a material. The firstwater turbine , which hadwater wheel s with curved blades onto whichwater flow was directed axially, was also first invented in the Islamic world, and was described in a 9th century Arabic text for use in awatermill .Labour force
The
labor force in theCaliphate wereemployed from diverseethnic andreligious backgrounds, while both men and women were involved in diverse occupations andeconomic activities. [Maya Shatzmiller, pp. 6–7.] Women were employed in a wide range of commercial activities and diverse occupations in the primary sector (asfarmer s for example), secondary sector (asconstruction worker s,dye rs, spinners, etc.) and tertiary sector (asinvestor s, doctors,nurse s,president s ofguild s,broker s,peddler s,lender s,scholar s, etc.). [Maya Shatzmiller, pp. 350–62.] Muslim women also held amonopoly over certain branches of thetextile industry , the largest and most specialized and market-oriented industry at the time, in occupations such asspinning ,dying , andembroidery . In comparison, femaleproperty rights andwage labour were relatively uncommon inEurope until theIndustrial Revolution in the 18th and 19th centuries. [Maya Shatzmiller (1997), "Women and Wage Labour in the Medieval Islamic West: Legal Issues in an Economic Context", "Journal of the Economic and Social History of the Orient" 40 (2), pp. 174–206 [175–7] .]The
division of labour was diverse and had been evolving over the centuries. During the 8th–11th centuries, there were on average 63 unique occupations in theprimary sector of economic activity (extract ive), 697 unique occupations in thesecondary sector (manufacturing ), and 736 unique occupations in thetertiary sector (service). By the 12th century, the number of unique occupations in the primary sector and secondary sector decreased to 35 and 679 respectively, while the number of unique occupations in the tertiary sector increased to 1,175. These changes in the division of labour reflect the increasedmechanization and use ofmachine ry to replacemanual labour and the increasedstandard of living andquality of life of most citizens in the Caliphate. [Maya Shatzmiller, pp. 169–70.]An economic transition occurred during this period, due to the diversity of the service sector being far greater than any other previous or contemporary society, and the high degree of
economic integration between the labour force and theeconomy . Islamic society also experienced a change in attitude towardsmanual labour . In previous civilizations such asancient Greece and in contemporary civilizations such asearly medieval Europe, intellectuals saw manual labour in a negative light and looked down on them with contempt. This resulted in technological stagnation as they did not see the need formachine ry to replace manual labour. In the Islamic world, however, manual labour was seen in a far more positive light, as intellectuals such as theBrethren of Purity likened them to a participant in the act ofcreation , whileIbn Khaldun alluded to the benefits of manual labour to the progress of society.Maya Shatzmiller, pp. 400–1.]Mechanical technology
Noria andchain pump (saqiya) machines became more widespread during the Muslim Agricultural Revolution, when Muslim engineers made a number of improvements to the device.Thomas F. Glick (1977), "Noria Pots in Spain", "Technology and Culture" 18 (4), pp. 644–50.] These include the first uses of noria and chain pumps forirrigation purposes, and the invention of theflywheel mechanism, used to smooth out the delivery of power from a driving device to a driven machine, which was first invented by Ibn Bassal (fl. 1038–75) ofal-Andalus , who pioneered the use of the flywheel in the saqiya and noria. [Ahmad Y Hassan , [http://www.history-science-technology.com/Notes/Notes%204.htm Flywheel Effect for a "Saqiya"] .]In 1206,
al-Jazari invented a variety of machines for raising water, which were the most efficient in his time, as well aswater wheel s withcam s on theiraxle used to operateautomata . He invented thecrankshaft andconnecting rod , and employed them in a crank-connecting rod system for two of these water-raising machines. His invention of the crankshaft is considered the most important single mechanical invention after thewheel , as it transforms continuous rotary motion into a linear reciprocating motion, and is central to modern machinery such as thesteam engine and theinternal combustion engine . [Ahmad Y Hassan . [http://www.history-science-technology.com/Notes/Notes%203.htm The Crank-Connecting Rod System in a Continuously Rotating Machine] .] Al-Jazari's most sophisticated water-raising machine featured the firstsuction pipes and suctionpump , the first use of the double-action principle, the first Reciprocating suction piston pump, the earliestvalve operations, and the use of a water wheel and a system ofgear s. This invention is important to the development of modern machinery, including the steam engine, modern reciprocating pumps, [Ahmad Y Hassan .

Egypt ian engineerTaqi al-Din described an early practicalsteam turbine as a for rotating a spit. A similar device appeared later in Europe a century later. [Ahmad Y Hassan (1976). "Taqi al-Din and Arabic Mechanical Engineering", pp. 34–5. Instiute for the History of Arabic Science,University of Aleppo .]Other technologies
A significant number of inventions and technological advances were made in the Muslim world, as well as adopting and improving technologies centuries before they were used in the West. For example,
papermaking was adopted from China many centuries before it was known in the West. [Huff (2003), p. 74] Iron was a vital industry in Muslim lands and was given importance in the Qur'an. [cite quran|57|25|style=ref] [Hobson (2004), p. 130] The knowledge ofgunpowder was also transmitted from China toIslamic countries , where Muslim chemists were the first to purifysaltpeter to theweapons-grade purity for use ingunpowder , aspotassium nitrate must be purified to be used effectively. This purification process was first described by Ibn Bakhtawayh in his "Al-Muqaddimat" in the early 11th century. [Ahmad Y Hassan , [http://www.history-science-technology.com/Articles/articles%202.htm Potassium Nitrate in Arabic and Latin Sources] ] [Ahmad Y Hassan , [http://www.history-science-technology.com/Articles/articles%203.htm Gunpowder Composition for Rockets and Cannon in Arabic Military Treatises In Thirteenth and Fourteenth Centuries] ] Gunpowder weapons were employed by Muslim armies againstChristian armies during theCrusades andByzantine-Ottoman wars . [Phillips (1992), p. 76] Knowledge of chemical processes (alchemy andchemistry ) anddistillation (alcohol ,kerosene and otherchemical substance s) also spread to Europe from the Muslim world. Numerous contributions were made in laboratory practices such as "refined techniques ofdistillation , the preparation ofmedicine s, and the production ofsalt s." [Levere (2001), p. 6] Advances were made inirrigation and farming, using technology such as thewindmill . Crops such asalmond s andcitrus fruit were brought to Europe throughal-Andalus , andsugar cultivation was gradually adopted by the Europeans. [Mintz (1986), pp. 23–9]Fielding H. Garrison wrote in the "History of Medicine":A significant number of other inventions were also produced by medieval Muslim scientists and engineers, including inventors such as
Abbas Ibn Firnas ,Taqi al-Din , and especiallyal-Jazari , who is considered the "father ofrobotics " and "father of modern dayengineering ". [ [http://www.mtestudios.com/news_100_years.htm 1000 Years of Knowledge Rediscovered at Ibn Battuta Mall] , MTE Studios.]Some of the other inventions and advances during the Muslim Agricultural Revolution include the

There was a significant increase in
urbanization during this period, due to numerous scientific advances in fields such as agriculture,hygiene ,sanitation , astronomy, medicine and engineering. This also resulted in a risingmiddle class population. [Avner Greif (1989), "Reputation and Coalitions in Medieval Trade: Evidence on the Maghribi Traders", "The Journal of Economic History" 49 (4), pp. 857–82 [862, 874] .]As urbanization increased, Muslim cities grew unregulated, resulting in narrow winding city
street s andneighborhood s separated by different ethnic backgrounds and religious affiliations. These qualities proved efficient for transporting goods to and from major commercial centers while preserving the privacy valued by Islamic family life. Suburbs lay just outside the walled city, from wealthy residential communities, to working class semi-slums. City garbage dumps were located far from the city, as were clearly defined cemeteries which were often homes for criminals. A place of prayer was found just near one of the main gates, for religious festivals and public executions. Similarly, Military Training grounds were found near a main gate.While varying in appearance due to climate and prior local traditions, Islamic cities were almost always dominated by a
merchant middle class. Some peoples' loyalty towards their neighborhood was very strong, reflecting ethnicity and religion, while a sense of citizenship was at times uncommon (but not in every case). The extended family provided the foundation for social programs, business deals, and negotiations with authorities. Part of this economic and social unit were often the tenants of a wealthy landlord.State power normally focused on Dar al Imara, the governor's office in the
citadel . These fortresses towered high above the city built on thousands of years of human settlement. The primary function of the city governor was to provide for defence and to maintain legal order. This system would be responsible for a mixture of autocracy and autonomy within the city. Each neighborhood, and many of the large tenement blocks, elected a representative to deal with urban authorities. These neighborhoods were also expected to organize their young men into a militia providing for protection of their own neighborhoods, and as aid to the professional armies defending the city as a whole.The head of the family was given the position of authority in his household, although a
qadi , or judge was able to negotiate and resolve differences in issues of disagreements within families and between them. The two senior representatives of municipal authority were the qadi and themuhtasib , who held the responsibilities of many issues, including quality of water, maintenance of city streets, containing outbreaks of disease, supervising the markets, and a prompt burial of the dead.Another aspect of Islamic urban life was
waqf , a religious charity directly dealing with theqadi and religious leaders. Through donations, the waqf owned many of thepublic bath s andfactories , using the revenue to fund education, and to provideirrigation fororchard s outside the city. Following expansion, this system was introduced intoEastern Europe byOttoman Turks .While religious foundations of all faiths were tax exempt in the Muslim world, civilians paid their taxes to the urban authorities, soldiers to the superior officer, and landowners to the state treasury. Taxes were also levied on an unmarried man until he was wed. Instead of
zakat , the mandatory charity required of Muslims, non-Muslims were required to pay thejizya , a discriminatory religious tax, imposed on Christians and Jews. During the Muslim Conquests of the 7th and 8th centuries conquered populations were given the three choices of either converting to Islam, paying the jizya, or dying by the sword.Animals brought to the city for slaughter were restricted to areas outside the city, as were any other industries seen as unclean. The more valuable a good was, the closer its market was to the center of town. Because of this, booksellers and goldsmiths clustered around the main mosque at the heart of the city.
Civil engineering
Many
dam s,acequia andqanat water supply systems, and "Tribunal of Waters"irrigation systems, were built during the Islamic Golden Age and are still in use today in the Islamic world and in formerly Islamic regions of Europe such asSicily and theIberian Peninsula , particularly in theAndalusia ,Aragon and Valencia provinces ofSpain . The Arabic systems of irrigation and water distribution were later adopted in theCanary Islands andAmericas due to the Spanish and are still used in places likeTexas ,Mexico ,Peru , andChile .Ahmad Y Hassan , [http://www.history-science-technology.com/Articles/articles%2071.htm Transfer Of Islamic Technology To The West, Part II: Transmission Of Islamic Engineering] ]Muslim cities also had advanced
domestic water system s withsewer s,public bath s, drinkingfountain s, pipeddrinking water supplies, [Fiona MacDonald (2006), "The Plague and Medicine in the Middle Ages", pp. 42–3, Gareth Stevens, ISBN 0836859073.] and widespread private andpublic toilet andbathing facilities. [Tor Eigeland, "The Tiles of Iberia", "Saudi Aramco World ", March-April 1992, pp. 24–31.] By the 10th century, Cordoba had 700mosque s, 60,000palace s, and 70 libraries, the largest of which had 600,000 books, while as many as 60,000treatise s, poems,polemic s and compilations were published each year inal-Andalus . [Dato' Dzulkifli Abd Razak, [http://www.prn2.usm.my/mainsite/bulletin/article/29dar05.html Quest for knowledge] , "New Sunday Times",3 July 2005 .] The library ofCairo had more than 100,000 books, while the library of Tripoli is said to have had as many as three million books. The number of important and original Arabic works on science that have survived is much larger than the combined total of Greek andLatin works on science. [N. M. Swerdlow (1993). "Montucla's Legacy: The History of the Exact Sciences", "Journal of the History of Ideas" 54 (2), pp. 299–328 [320] .]Islamic cities also had an early public
health care service. "The extraordinary provision of public bath-houses, complexsanitary systems ofdrainage (more extensive even than the famous Roman infrastructures), fresh water supplies, and the large and sophisticated urban hospitals, all contributed to the general health of the population."
