Muhammad I of Granada

Muhammad ibn Yusuf ibn Nasr (c. 1195–1273), called Ibn al-Ahmar, was founder of the Nasrid dynasty and first emir of Granada, the last independent Muslim state on the Iberian Peninsula. He seized his native Arjona in 1232 and entered Granada in 1237.

In 1246 he surrendered Jaén to Ferdinand III of Castile and became his vassal, even aiding the Christian capture of Seville in 1248. In 1264 he turned against Castile and supported an unsuccessful Muslim rebellion; two years later his former allies rebelled against him. He began building the Alhambra. He died in 1273 after a fall from his horse.
