Suleiman II (15 April 1642 – 22 June 1691) ( "Süleymān-i sānī") was the Sultan of the Ottoman Empire from 1687 to 1691. After being brought to the throne by an armed mutiny, Suleiman and his grand vizier Fazıl Mustafa Pasha were successfully able to turn the tide of the War of the Holy League, reconquering Belgrade in 1690, as well as carrying out significant fiscal and military reforms.
