Mamluk architecture was the architectural style that developed under the Mamluk Sultanate (1250–1517), which ruled over Egypt, the Levant, and the Hijaz from their capital, Cairo. Despite their often tumultuous internal politics, the Mamluk sultans were prolific patrons of architecture and contributed enormously to the fabric of historic Cairo. The Mamluk period, particularly in the 14th century, oversaw the peak of Cairo's power and prosperity. Their architecture also appears in cities such as Damascus, Jerusalem, Aleppo, Tripoli, and Medina.
