Muhammad VIII (Arabic: محمد الثامن; 1411–1431), known as "the left handed", was the fourteenth Nasrid ruler of the Islamic Emirate of Granada in Al-Andalus on the Iberian Peninsula.
He, as eldest son, became Sultan after the death of his father Yusuf III.[1] His first reign lasted from 1417 to 1419, and his second from 1427 to 1429.[2] Immediately after coming to the throne, Muhammad renewed the treaties between Granada, Castile and the Marinids, and sent troops to help the Marinids in the Siege of Ceuta in 1418.
