Amir al-umara

From 928, Mu'nis was involved in a tumultuous power struggle with his rivals in the court's civilian bureaucracy, which ended with the deposition and execution of al-Muqtadir in 932, and his replacement with his brother al-Qahir (r. 932–934).

[7] The historian Ali ibn al-Athir (d. 1233) asserted that after the death of Mu'nis, the post of amir al-umara fell to Tarif al-Subkari, who was also head of the treasury.

According to the contemporary scholar Miskawayh, he was named governor of Baghdad and commander-in-chief of the army, was entrusted with the collection of the kharaj land tax and the supervision of all public estates, as well as the maintenance of security.

[4] Despite his extraordinary authority, however, Ibn Ra'iq failed to stabilize the situation and a decade-long complicated power struggle between various regional leaders followed for the office of amir al-umara.

On 9 September 938 Ibn Ra'iq was deposed by his former subordinate, the Turk Bajkam, who secured his own succession to the post four days later, and ruled until his death by Kurdish brigands on 21 April 941.

Caliph al-Muttaqi (r. 940–944), raised to the throne by Bajkam after al-Radi's death, now tried to restore civilian rule, appointing Ibn Maymun and then Abu Abdallah al-Baridi as viziers, but the military retook control under the leadership of Kurankij, who became amir al-umara on 1 July.

The Hamdanids too were unable to consolidate their control in the face of financial difficulties, and a military revolt under the Turkish general Tuzun forced Nasir al-Dawla to abandon his post (11 May 943) and retreat to his base at Mosul.

After Tuzun's death, his secretary and successor, Muhammad ibn Shirzad, held only feeble authority and tried to fend off the Buyid threat by allying himself with Nasir al-Dawla.

[15] Possession of the title of amir al-umara formed the institutional framework of Buyid authority in Baghdad itself and vis-a-vis the caliph, who now became simply another state functionary and was given an annual salary.

[5][16] Further east, neither the Samanid Empire nor the Ghaznavids appear to have employed it often, except for the case of Abu Ali Simjuri, a rebel military commander who took control of Khorasan in 991 and proclaimed himself amir al-umara.

It only reappeared occasionally in the late Safavid period, when it designated a military commander exceptionally appointed to a border region threatened with foreign invasion.
