'Imad al-Daula

'Ali ibn Buya "'Imad al-Daula" (c. 891/2 – December 949) was the founder of the Buyid dynasty in Iran (in Shiraz, 934–949).

Early career

'Ali first entered the services of the Samanids under Nasr II, where he became a member of the ruler's entourage. From there he eventually joined Makan, who ruled Gorgan and Ray as a governor of the Samanids, in around 928. He may have done so at Nasr's suggestion; in any case, he managed to occupy a high position under Makan and gained army commissions for his two younger brothers, Hasan and Ahmad. In 930, however, Makan rebelled against the Samanids by seizing Khurasan; he was subsequently attacked by the Ziyarid prince Mardavij and forced to give up Tabaristan.

'Ali and his brothers managed to defect to Mardavij's side just as the Ziyarid was preparing to undertake the conquest to the south of the Alborz mountains as far as Qazvin. Not long afterwards Mardavij granted 'Ali administrative rule over Karaj, a strategically important town probably situated near modern Bahramabad. While making a stop in Ray on his way to Karaj, however, 'Ali was warned by Mardavij's vizier al-'Amid that the Ziyarid was planning to eliminate him. Hurredly leaving Ray, he arrived at and took over Karaj.

With a small number of Dailamite troops to support him, 'Ali sought to expand his position. Moving against the heretical Khurramites, who controlled the surrounding mountains, he gained control of the region and was heavily enriched by the expeditions. At the same time, he managed to maintain his troops' loyalty, despite Mardavij's attempts to incite them against their master.

Foundation of the Buyid state

In order to further secure his position, 'Ali decided to seize the nearby city of Isfahan, then under control of the Abbasid governor Yaqut. The enemy army outnumbered 'Ali's, but a large portion of it defected to him upon his appearance before the city. Yaqut, however, refused to negotiate with him, and Mardavij's approach forced him to abandon Isfahan in favor of the Ziyarids. Having fled Karaj as well, 'Ali now took Arrajan, a city between Fars and Khuzestan.

Having stayed for the winter in Arrajan, 'Ali decided to campaign in Fars in the spring of 933. There he encountered the resistance of Yaqut, who was also the governor of Fars and from whom 'Ali had stripped Arrajan. He also found an ally, Zaid ibn 'Ali al-Naubandagani, a wealthy landowner who disliked the Abbasids. After a series of battles, 'Ali managed to prove the victor. By May or June of 934, he entered Shiraz, the capital of Fars.

In order to prevent Mardavij from pressing claims on his territory, 'Ali sought the recognition of the Abbasid Caliph, who confirmed him as his viceroy in September or October of 934. Although the caliph's emissary arrived with the insignia for his office, however, 'Ali delayed giving the requisite tribute; by the time the emissary died in Shiraz two years later, the tribute was still unpaid.

Mardavij continued to pose a threat; he decided to invade Khuzestan, which was still under caliphal control, in order to sever the Buyids from the Caliphate. This invasion prompted the caliph to reach an agreement with the Ziyarid, which forced 'Ali to recognize Mardavij's authority. This recognition proved short-lived, as Mardavij was assassinated in January of 935. 'Ali then decided to press claims on Khuzestan, and occupied 'Askar Mukram. The Buyid and the caliph then came to terms with one another; the latter confirmed 'Ali in his possession of Fars and gave Khuzestan to Yaqut.

The Buyid empire takes shape

Bolstered by many of Mardavij's Turkish mercenaries that had joined him, as well as the collapse of Ziyarid control over central Iran, 'Ali decided that Isfahan should be taken. He sent his brother Hasan to accomplish this. Hasan initially managed to take Isfahan but later encountered difficulties (for details about his campaigns in central Iran, see Rukn al-Daula). After Hasan took Isfahan, 'Ali sent his other brother Ahmad (see Mu'izz al-Daula) to take Kerman. Although the bulk of that province was compelled to recognize Buyid authority, direct control was not established, and 'Ali eventually recalled him.

'Ali next sent Ahmad to Khuzestan, where the Basrian clan of the Baridis had become the de facto rulers of the province but were trying to throw off caliphal rule. They asked 'Ali for their struggle against the Abbasids, providing the pretext for Ahmad to enter Khuzestan. Although the Baridis temporarily recovered the province and even managed to take Baghdad a few times, Ahmad eventually took control of Khuzestan himself. From Khuzestan Ahmad waged a series of campaigns in Iraq, until in 945 he entered Baghdad. The caliph then gave him the title of "Mu'izz al-Daula," while 'Ali and Hasan were given the titles of "'Imad al-Daula" and "Rukn al-Daula," respectively. By 948 Rukn al-Daula had also secured his position in central Iran, causing a clear definition of the borders of the Buyid state.

'Imad al-Daula was not the master of the entire Buyid empire. Rukn al-Daula, partly as a result of 'Imad al-Daula's failure to send him military support during his struggles in central Iran, was relatively independent of his brother. Mu'izz al-Daula, on the other hand, had been given support by his brother in his efforts to take Khuzestan, and was a subordinate of 'Imad al-Daula. He was not listed as an independent ruler on contemporary sources, and the name of his brother appeared before his own on coins struck by him. Despite the fact that Mu'izz al-Daula's capture of Baghdad resulted in him gaining the title of senior amir (amir al-umara'), which in theory made him the highest ranking individual out of all three Buyids, he remained little more than a provincial ruler under 'Imad al-Daula's authority. 'Imad al-Daula himself claimed the title of senior amir during his lifetime, and although he never officially held it, nor was entitled to do so, he was recognized as the de facto holder of that position.

'Imad al-Daula's lack of an heir posed a problem until shortly before his death. A few months beforehand, he settled on Rukn al-Daula's eldest son Fana-Khusrau as his successor. He died in December of 949, and his brothers helped to install Fana-Khusrau (who took the title of "'Adud al-Daula") in Shiraz. Rukn al-Daula, who was the most powerful of the Buyids, claimed the title of senior amir for himself and received both Mu'izz al-Daula's and 'Adud al-Daula's recognition as such.
