Saif ad-Din Abu-Bakr

Al-Malik al-Mansur Sayf ad-Din Abu Bakr, better known as al-Mansur Abu Bakr, was a Bahri Mamluk Sultan of Egypt in 1341. From an early age, Abu Bakr received military training in the desert town of al-Karak. His father, Sultan an-Nasir Muhammad, groomed him as a potential successor to the throne and made him an emir in 1335. He was consistently promoted in the following years, becoming the na'ib (governor) of al-Karak in 1339. In June 1341, he became sultan, the first of several sons of an-Nasir Muhammad to accede to the throne. However, his reign was short-lived; in August, Abu Bakr was deposed and arrested by his father's senior emir, Qawsun. Abu Bakr was imprisoned in the Upper Egyptian city of Qus, along with many of his brothers, and executed on Qawsun's orders two months later. He was formally succeeded by his younger half-brother, al-Ashraf Kujuk, but Qawsun was left as the strongman of the sultanate.
