Muhammad IV of Granada
Muhammad IV (1315–1333), son of Ismail I and Alwa, became sixth Nasrid sultan of Granada in 1325 after his father's assassination. Civil war followed between vizier Ibn al-Mahruq and Uthman ibn Abi al-Ula, who with Castilian backing proclaimed his uncle sultan.
He ceded Ronda, Marbella and Algeciras to the Marinids, probably in exchange for their aid, then in 1328 took power, reconciling Uthman and killing the vizier. In 1333 he helped the Marinids capture Gibraltar and made peace with Castile; the day after the truce he was assassinated on the orders of Uthman's sons, and his brother Yusuf I succeeded.
