Abu Said Uthman III (Arabic: عثمان الثاني المريني) (Abu Said Uthman ibn Abi l-Abbas ibn Abi Salim), (1383 – 21 October 1420) was Marinid ruler of Morocco from 19 March 1398 to 1420, the last effective ruler of that dynasty. He ascended to the throne at the age of sixteen.[1] He succeeded his brother, Abu Amir Abdallah ibn Ahmad. His forces were involved in an unsuccessful attempt to acquire Gibraltar from the Emirate of Granada in 1410. In 1415 the Portuguese seized the port of Ceuta. Abu Said Uthman III failed in an attempt to recover Ceuta, and was shortly after assassinated. His vizier gained control of the kingdom, establishing the Wattasid dynasty of rulers of Morocco.
