Petty kingdom

A petty kingdom is an independent realm recognizing no suzerain and controlling only a portion of the territory held by a particular ethnic group or nation. Petty kingdoms were prominent before the formation of many of today's nation-states. Many of today's countries were typically ruled by multiple local kings in more or less stable kingdoms. The various small states of the Holy Roman Empire are generally not considered to be petty kingdoms since they were at least nominally subject to the Holy Roman Emperor and not fully independent.

England

Before the Kingdom of England was established as a united entity, there were various kingdoms in the area - of which the main seven were known as the heptarchy. These were Wessex, Mercia, Northumbria (also extended into present-day Scotland), East Anglia, Sussex, Kent, and Essex.

erbia

Medieval Serbia comprised, at various time periods, smaller kingdoms of Rascia, Zeta (Dioclea, corresponding to portions of contemporary Montenegro) and the duchy of Hum (roughly corresponding to present-day Herzegovina and some of its surroundings).

Iberia

The Christian petty kingdoms of the Iberian Peninsula that eventually formed Spain (and thus not including Portugal, itself a nation-state) included prior to complete unification:
*Aragon
*Castile
*León (united with Castile after 1230)
*Navarre

See the article about the taifa for the Islamic petty kingdoms that existed in Iberia after the collapse of the Caliphate of Cordoba in 1031.

Ireland

The earliest known kingdoms or tribes in Ireland are referred to in Ptolemy's "Geography", written in the 2nd century. He names the Vennicni, Rhobogdi, Erdini, Magnatae, Autini, Gangani, Vellabori, Darini, Voluntii, Eblani, Cauci, Menapii, Coriondi and Brigantes tribes and kingdoms.

Irish medieval pseudohistory gives a seemingly idealized division of kingdoms. The island is divided into "fifths" (Old Irish "cóiceda", Modern Irish "cúige"). There is "Ulaid" (Ulster) in the north, "Cóiced Ol nEchmacht" (Connacht) in the west, "Mumha" or "Mhumhain" (Munster) in the south, and "Laighin" (Leinster) in the east. They all surround the central kingdom of Míde (whose name has survived in the modern counties Meath and Westmeath). Each of the outer four fifths had their own king, with the High King of Ireland ruling over them from Tara in Míde.

In historical times Míde disappeared as a province. The four remaining fifths contained large numbers of "tuatha" or sub-kingdoms, constantly shifting as old dynasties died and new ones formed.

Norway

In the early Viking Age, there were several different petty kingdoms. Spurred by the unification of several of these kingdoms under Halfdan the Black, his son Harald Fairhair was able to unite them all in 872.

Some of the kingdoms:
* Agder
* Grenland
* Hadeland
* Hardanger
* Hedmark
* Hålogaland
* Land
* Namdalen
* Nordmøre
* Oppland
* Orkdal
* Rogaland
* Romsdal
* Sogn
* Solør
* Sunnmøre
* Telemark
* Toten
* Trøndelag
* Vestfold
* Vingulmark
* Voss

cotland

* Dál Riata
* Gododdin
* Pictavia
* Fortriu

weden

According to the Norse sagas, and modern history, Sweden was divided into more or less independent units in some areas corresponding to the folklands and the modern traditional provinces. According to the sagas, the folklands and provinces of eastern Svealand were united under the Swedish king at Gamla Uppsala. Moreover, the domains of this king could also include parts of Götaland and even southern Norway. This probably reflects the volatile politics of Iron Age Scandinavia. The province of Småland once consisted of several petty kingdoms as also the meaning of the word Småland reveals (Små land = Small Lands/countries).dubious|Date=June 2008 See Finnveden, Njudung and Värend for instance.
