Battle of Marj Dabiq
The Ottoman Empire captured Gaziantep after the Battle of Marj Dabiq in 1516, under the reign of Sultan Selim I. In the Ottoman period, Aintab was a sanjak centered initially in the Dulkadir Eyalet (1516–1818), and later in the Aleppo vilayet (1908–1918). It was also a kaza in the Aleppo vilayet (1818–1908). The city established itself as a centre for commerce due to its location straddling trade routes.
