Meaning of 'ISA IBN MUSA in English

'ISA IBN MUSA

died 784 nephew of the first two 'Abbasid caliphs, military leader, and at one time presumptive heir to the caliphate. The caliph as-Saffah nominated his brother al-Mansur and, after him, 'Isa, as heirs. On the accession of al-Mansur, 'Isa was governor of Kufah. The new caliph sent him to lead an army against an 'Alid revolt in Medina, apparently with the hope that he might be killed. In a series of battles, 'Isa secured al-Mansur's rule but was forced by intimidation to renounce his rights of succession to al-Mansur's son Muhammad al-Mahdi. On al-Mansur's death, 'Isa again pressed his claim and was defeated in favor of al-Mahdi's son Musa al-Hadi.
