The Burji Mamluks or Circassian Mamluks, sometimes referred to as the Burji dynasty, were the rulers of the Mamluk Sultanate of Egypt from 1382 until 1517. As with the preceding Bahri Mamluks, the members of the Burji Mamluk ruling class were purchased as slaves (mamluks) and manumitted, with the most powerful among them taking the role of sultan in Cairo. During this period, the ruling Mamluks were generally of Circassian origin, drawn from the Christian population of the northern Caucasus. The name Burji, meaning 'of the tower', refers to the traditional residence of these Mamluks in the barracks of the Citadel of Cairo.

Al-Malik Az-Zahir Sayf ad-Din Barquq was the first Sultan of the Circassian Mamluk Burji dynasty of Egypt ruling from 1382 to 1389 and 1390 to 1399. Born to a Christian father in Circassia, Barquq was enslaved and later arrived in Egypt. He deposed sultan al-Salih Hajji to claim the throne for himself. Once in power, he placed many of his family members in positions of power. Rebelling governors in 1389 restored Hajji to the throne but Barquq was able to reclaim the throne shortly after and ruled until his death in 1399 and was succeeded by his son. The name Barquq is of Circassian origin and is his birth name.
