The Battle of Alcácer Quibir (also known as "Battle of Three Kings" (Arabic: معركة الملوك الثلاثة) or "Battle of Wadi al-Makhazin" (Arabic: معركة وادي المخازن) in Morocco) was fought in northern Morocco, near the town of Ksar-el-Kebir (variant spellings: Ksar El Kebir, Alcácer-Quivir, Alcazarquivir, Alcassar, etc.) and Larache, on 4 August 1578. A Moroccan victory, the battle has been described as "the greatest military disaster the Portuguese ever suffered in the course of their overseas expansion." It marked an end to Portuguese attempts to reconquer territories it had lost in Morocco. The combatants were the army of the deposed Moroccan Sultan Abu Abdallah Mohammed II, with his ally, the King of Portugal Sebastian I, against a large Moroccan army under the new Sultan of Morocco (and uncle of Abu Abdallah Mohammed II) Abd Al-Malik I. The Christian king Sebastian I had planned a crusade after Abu Abdallah asked him to help recover his throne. Abu Abdallah's uncle, Abd Al-Malik, had taken it from him with Ottoman support.
