Al-Ashraf Sayf-ad-Din Barsbay was the ninth Burji Mamluk sultan of Egypt from AD 1422 to 1438. He was Circassian by birth and a former slave of the first Burji Sultan, Barquq.
He was responsible for a number of administrative reforms in the Mamluk state, including the consolidation of the sultanate as a military magistrature and securing for Egypt exclusive rights over the Red Sea trade between Yemen and Europe.
His Red Sea activity included the final destruction in 1426 of ‘Aydhab, a once important port which had been in decline in the previous century.
In 1426-1427 he reconquested Cyprus.
In 1430 Egypt was severely struck by famine and plague.
His mausoleum, which included a madrasa and khanqah, was built in Cairo's Northern Cemetery, and has survived to this day.
