Abu Yaqub Yusuf an-Nasr
Abu Yaqub Yusuf an-Nasr (c. 1230–13 May 1307) succeeded his father as Marinid sultan in 1286, and faced revolts including from his own son Abu Amir. After Castile took Tarifa in 1292 he failed to recover it, and in 1295 ceded Algeciras to Granada, abandoning Spain.
He then turned on Tlemcen, besieging it from 1299 at al-Mansura. On 13 May 1307, as the city neared surrender, a eunuch killed him in his camp, and the siege ended under his successor Abu Thabit.
