Al-Muʿtazz then invested ʿUtāmish—while leaving him in charge of the vizierate—with the command of Egypt and all the western provinces.
He banished ʿUbayd Allāh ibn Yaḥyā ibn Khāqān to Barqah, and distributed two million dinars among the troops.
While campaigning in Byzantine territory, ʿAlī ibn Yaḥyā al-Armanī and ʿUmar al-Aqṭaʿ were killed.

The number of Turkish soldiers in Baghdad swelled; they entrenched themselves, dealt harshly with the people, and oppressed the populace. The Shakariyya and the regular army therefore rose up, burned the bridge, and plundered the government chanceries.
A similar disturbance broke out in Sāmarrāʾ. Bughā and ʿUtāmish mounted up, drew the sword, and killed many. The common people rallied together (1) and slew a party of Turks; the crisis deepened. Waṣīf came out and ordered the marketplaces to be set ablaze. Shortly afterward ʿUtāmish was killed, Ibn Yazdād became vizier, and Jaʿfar al-Hāshimī was removed from the judiciary.

At the turn of 250 AH, al-Ḥasan ibn Zayd al-Ḥasanī rose in Ṭabaristān. His authority grew, he brought several cities under his rule, and every malcontent flocked to him. He defeated Ibn Ṭāhir’s army twice and reached Hamadhān, whereupon al-Mustaʿin dispatched an army against him (2).

That same year al-Mustaʿin invested his son ʿAbbās with authority over Iraq and the Ḥijāz.

In 251 AH, al-Ḥusayn ibn Aḥmad al-Ḥusaynī emerged in Qazwīn and seized it. He and Aḥmad ibn ʿĪsā al-Zaydī had made common cause, killed many people in Rayy, and sowed havoc until one of them was captured and the other killed.

In the Ḥijāz, Ismāʿīl ibn Yūsuf al-Ḥasanī also rebelled; the Bedouins followed him. He ravaged the land, spoiled the pilgrimage season, and killed more than a thousand members of the caravan, after which Allah struck him and many of his men with the plague.
