Abu Sa'id Qansuh was originally a young Circassian victim of the Black Sea slave trade purchased by Sultan Qaytbay.
When Muhammad took over, the Mamluks grew discontent with the Sultan, rebelled, killed him, and elected Abu Sa'id Qansuh in his place.
Facing another similar path as Sultan, the Mamluks became discontent with Qansuh.
Qansuh tried to flee the palace disguised as a woman, but was caught and exiled to Alexandria.
Qansuh was supposedly strangled to death by the orders of the future Sultan Tuman bay I.
