Bajkam, de facto regent of the Abbasid Caliphate

Abū al-Husayn Bajkam al-Mākānī, referred to as Bajkam, Badjkam or Bachkam, was a Turkish military commander and official of the Abbasid Caliphate. A former ghulam of the Ziyarid dynasty, Bajkam entered Abbasid service following the assassination of the Ziyarid ruler Mardavij in 935. During his five-year tenure at the Caliphate's court at Baghdad, he was granted the title of amir al-umara, consolidating his dominance over the caliphs al-Radi and al-Muttaqi and giving him absolute power over their domains. Bajkam was challenged throughout his rule by various opponents, including his predecessor as amir al-umara, Muhammad ibn Ra'iq, the Basra-based Baridis, and the Buyid dynasty of Iran, but he succeeded in retaining control until his death. He was murdered by a party of Kurds during a hunting excursion in 941, shortly after the accession of al-Muttaqi as Caliph. Bajkam was known both for his firm rule and for his patronage of Baghdad intellectuals, who respected and in some cases befriended him. His death led to a void in central power, resulting in a brief period of instability and fighting in Baghdad.
