Sayf al-Din Barquq
Barquq (c.1336–1399) was a Circassian brought to Egypt in 1364 as a mamluk of the amir Yalbugha al-Umari. Rising through the army, in 1382 he deposed the child sultan al-Salih Hajji and founded the Burji Mamluk dynasty.
Ousted in a revolt that restored Hajji in 1389, he retook the throne in 1390 and replaced almost all governors and senior officials with members of his own household.
After Timur took Baghdad in 1393 he allied with the Ottomans against him. He died in 1399, leaving the throne to his son Faraj.
