Mu'izz al-Dawla

Ahmad ibn Buya (died April 8, 967), better known by his laqab of Mu'izz al-Dawla, was the first of the Buwayhid emirs of Iraq, ruling from 945 until his death. He was the son of Buya.

Early career
During the Buwayhid conquest of Fars, Ahmad distinguished himself in battle. In 935 or 936, Ahmad's oldest brother 'Ali sent Ahmad to Kerman with the task of conquering that province from the Banu Ilyas. He overran much of Kerman, but encountered resistance from the Baluchis and Arab Qafs, receiving a wound to the head and losing a hand and several fingers on the other. Direct Buyid control over Kerman was not established, resulting in 'Ali's recall of Ahmad. The latter was then sent to Istakhr to await further orders.

Ahmad's next opportunity to expand the possessions of the Buyids came when the Baridis requested help from 'Ali. The Baridis, who ruled in Khuzestan, were nominally subordinate to the Abbasid Caliphate, but were attempting to establish their independence. Ahmad was sent by 'Ali to the area; he succeeded in uprooting the authority of the Baridis and taking control of that province. From Khuzestan he launched several campaigns into Iraq, where the Caliphate was in serious internal disarray. These expeditions were of his own initiative; 'Ali had not ordered them and did not send support for them.

Rule in Iraq
The fighting in Iraq took several years, but at last Ahmad gained control of Baghdad on December 19, 945 without a struggle. He took charge of the administration of the Caliphate by taking the position of amir al-umara'. The Caliph Al-Mustakfi also gave him the honorific title of "Mu'izz al-Dawla" ("Glorifier of the State"). 'Ali was given the title of "'Imad al-Dawla" ("Support of the State"); another of Ahmad's brothers, Hasan, who had gained control of northern Persia, gained the title of "Rukn al-Dawla" ("Pillar of the State"). Despite Al-Mustakfi's apparent acceptance of Buyid authority, Mu'izz al-Dawla blinded and deposed him in 946, and installed Al-Muti as Caliph.

The next two years of Mu'izz al-Dawla's life were spent securing his control over Iraq. The Hamdanid emir of Mosul and former amir al-umara, Nasir al-Dawla, attempted to seize Baghdad in 946. When they failed to do so, they gave up on the campaign, but remained hostile against the Buyids. The Baridis, who still controlled Basra and Wasit, were defeated and their lands taken by the Buyids in 947. Their defeat marked the end of major fighting. Mu'izz al-Dawla's only failure was against an amirate situated in the marshlands between Basra and Wasit; this was of little concern due to the amirate's small size.

Despite the fact that Mu'izz al-Dawla had taken control of Iraq by himself, he remained subordinate to 'Imad al-Dawla, who ruled in Shiraz. Coins bearing 'Imad al-Dawla's name in addition to his own were made. His title of amir al-umara', which in theory made him the senior amir of the Buyids, meant little in reality and was soon claimed by 'Imad al-Dawla. Although he maintained a certain level of independence, it was clear that he should respect the authority of the 'Imad al-Dawla.

When 'Imad al-Dawla died in 949 and Rukn al-Dawla took the title of senior amir, Mu'izz al-Dawla accepted the change of rulers. He also sent troops to Shiraz to ensure that Fana-Khusrau, who was the son of Rukn al-Dawla and 'Imad al-Dawla's successor, would take power there. Still, he raised objections when Fana-Khusrau requested the title of "Taj al-Dawla". The title of "Taj" ("crown") implied that Fana-Khusrau was superior to his father and uncle, provoking a reaction from Mu'izz al-Dawla. A more suitable title ("'Adud al-Dawla") was instead chosen.

Rukn al-Dawla's struggles in northern Persia against various enemies caused Mu'izz al-Dawla to send military aid for several years. This, combined with continually having to deal with the Hamdanids, prevented Mu'izz al-Dawla from expanding the borders of his state for several years. Despite this, he managed to annex Oman with military support from 'Adud al-Dawla, and shortly afterwards undertook a campaign against the Shahinids of the Mesopotamian marshlands. It was during this campaign that he died, in 967. His son 'Izz al-Dawla, whom he had named his successor during a serious illness in 955, took power following his death.

Impact and assessment
Mu'izz al-Dawla's entrance into Baghdad in 945 marked over a century of Buyid rule in Iraq, and also of Shi'ite Buyid control over the Sunni Caliphate. Nevertheless, by the time of his death several problems remained unsolved. The Buyids had difficulty becoming accustomed to Baghdad; Mu'izz al-Daula almost left the city in favor of Ahvaz. The enemies of the Buyids, such as the Hamdanids and the Byzantines, continued to pose a threat. The struggle for power between Baghdad and Shiraz that first showed itself during Mu'izz al-Dawla's lifetime exploded into violence soon after his death.

Finally, the hostility between the Turks and Dailamites in Baghdad continued to pose a problem. The Sunni Turks, who found their privileges eroded by the Dailamite troops that had entered Baghdad with their master in 945, constantly threatened to upset the internal stability of the state. Mu'izz al-Dawla at first favored the Dailamite troops but later attempted to compromise between the two groups, making a Turk named Sebük-Tegin his chief commander. 'Izz al-Dawla's ascension would soon upset this balance, however, resulting in internal disunity.
