The Bahri Mamluks, sometimes referred to as the Bahri dynasty, were the rulers of the Mamluk Sultanate of Egypt from 1250 to 1382, following the Ayyubid dynasty. The members of the Mamluk ruling class were purchased as slaves (mamluks) and manumitted, with the most powerful among them taking the role of sultan in Cairo. While several Bahri Mamluk sultans tried to establish hereditary dynasties through their sons, these attempts were ultimately unsuccessful, with the role of sultan often passing on to another powerful Mamluk.
