معركة مرج دابق
After the conquest of Egypt in 1517, the Ottoman Sultan Selim I left the country. Grand Vizier Yunus Pasha was awarded the governorship of Egypt. However, the sultan soon discovered that Yunus Pasha had created an extortion and bribery syndicate, and gave the office to Hayır Bey, the former Mamluk governor of Aleppo, who had contributed to the Ottoman victory at the Battle of Marj Dabiq.
