Mamluk Sultanate

Mamluk (Arabic: مملوك mamlūk (singular), مماليك mamālīk (plural), meaning "property", also transliterated as mamlouk, mamluq, mamluke, mameluk, mameluke, mamaluke or marmeluke) is an Arabic designation for slaves. The term is most commonly used to refer to Muslim slave soldiers and Muslim rulers of slave origin.

More specifically, it refers to:

The most enduring Mamluk realm was the knightly military caste in Egypt in the Middle Ages, which developed from the ranks of slave soldiers. These were mostly enslaved Turkic peoples,Egyptian Copts,Circassians,Abkhazians, and Georgians. Many Mamluks were also of Balkan origin (Albanians, Greeks, and South Slavs). The "mamluk phenomenon", as David Ayalon dubbed the creation of the specific warrior class, was of great political importance; for one thing, it endured for nearly 1000 years, from the ninth to the nineteenth centuries.

Over time, the mamluks became a powerful military knightly caste in various societies that were controlled by Muslim rulers. Particularly in Egypt, but also in the Levant, Mesopotamia, and India, mamluks held political and military power. In some cases, they attained the rank of sultan, while in others they held regional power as emirs or beys. Most notably, mamluk factions seized the sultanate centered on Egypt and Syria, and controlled it as the Mamluk Sultanate (1250–1517). The Mamluk Sultanate famously defeated the Ilkhanate at the Battle of Ain Jalut. They had earlier fought the western European Christian Crusaders in 1154–1169 and 1213–1221, effectively driving them out of Egypt and the Levant. In 1302 the mamluks formally expelled the last Crusaders from the Levant, ending the era of the Crusades.
