The decade following al-Mutawakkil's assassination was a turbulent period, sometimes known as the Anarchy at Samarra, during which the capital was frequently beset by palace coups and troop riots. Al-Mutawakkil's son al-Muntasir (r. 861–862) abandoned al-Ja'fari and moved back to the Jawsaq palace, which remained the residence of his successors. Al-Musta'in (r. 862–866), finding it impossible to control the Samarran regiments, left the city and attempted to establish himself in Baghdad in 865, but the Turks and other troops responded by deposing him and besieging Baghdad until the caliph agreed to abdicate. His two successors, al-Mu'tazz (r. 866–869) and al-Muhtadi (r. 869–870), were similarly overthrown by the army.
