The Fall of Tlemcen occurred in 1517, when the Ottoman admiral Oruç Barbarossa captured the city of Tlemcen from its sultan, Abu Zayan, the last member of the Banu Zayan lineage. The fall of Tlemcen followed the capture of Ténès, also by Oruç and his brother, Hayreddin. The Sultan of Tlemcen then fled to Fez in Morocco. Oruç crowned himself king of Tlemcen. The only survivor of Abu Zayan's dynasty was Sheikh Buhammud, who escaped to Oran and called for Spain's assistance. Soon however, the king of Morocco raised a considerable army and marched on Tlemcen, expelling the Spanish.
