List of campaigns of Suleiman the Magnificent
The imperial campaigns (, "sefer-i humāyūn") of Suleiman the Magnificent were a series of campaigns led by Suleiman, who was the tenth and longest-reigning Sultan of the Ottoman Empire. He is known in the Western world as "Suleiman the Magnificent", and in the East as "the Lawgiver" (), for his complete reconstruction of the Ottoman legal system. During his reign from 1520 to his death in 1566, the Ottoman Empire became the most powerful state in the world. At its height, the Empire stretched from Hungary to Yemen.
Selim I
Selim then conquered the Mamluk Sultanate of Egypt, defeating the Mamluk Egyptians first at the Battle of Marj Dabiq, and then at the Battle of Ridanieh. This led to the Ottoman annexation of the entire sultanate, from Syria and Palestine in Sham, to Hejaz and Tihamah in the Arabian Peninsula, and ultimately Egypt itself. This permitted him to extend Ottoman power to the Muslim holy cities of Mecca and Medina, hitherto under Egyptian rule. Rather than style himself the "Ḥākimü'l-Ḥaremeyn", or "The Ruler of The Two Holy Cities", he accepted the more pious title "Ḫādimü'l-Ḥaremeyn", or "The Servant of The Two Holy Cities".
