The first of the Circassian Mamluk Sultans, Barquq assumed power after a series of political intrigues that led to the downfall (and often deaths) of the Bahri (Tartar) Mamluks. Barquq (whose name means "the plum") took power in 1386 and rescued the country from the ravages of the Black Death and related famine and political unrest. His madrasa has an octagonal minaret with marble-inlaid carved stone. Notice the columns attached to the wall in the facade; one of them shows a stylized ram's head in the capital. The cruciform interior is spacious and austere, except for an ornate carved and gilded ceiling in the sanctuary (restored in modern times), and the qibla (the direction of Mecca) wall, decorated in marble dado.
