Yahya ibn Umar ibn Rahhu
Yahya ibn Umar ibn Rahhu was a Zenata Berber commander in Nasrid Granada and son-in-law of Uthman ibn Abi al-Ula, the Volunteers of the Faith's chief. In December 1326, amid civil war, the vizier named him rival commander of the Volunteers, drawing their troops from Uthman. Around 1340 Sultan Yusuf I made him chief.
After 1354 he governed for Muhammad V, maintaining peace with Castile and paying it tribute. When Ismail II seized power in 1359, Yahya stayed loyal and fled to Castile with two hundred horsemen, finding asylum in Cordoba before rejoining the exiled sultan in 1361.
