Transformation of the Ottoman Empire

The transformation of the Ottoman Empire, also known as the Era of Transformation, constitutes a period in the history of the Ottoman Empire from c. 1550 to c. 1700, spanning roughly from the end of the reign of Suleiman the Magnificent to the Treaty of Karlowitz at the conclusion of the War of the Holy League. This period was characterized by numerous dramatic political, social, and economic changes, which resulted in the empire shifting from an expansionist, patrimonial state into a bureaucratic empire based on an ideology of upholding justice and acting as the protector of Sunni Islam.
