The Dughlat clan (Kazakh: Дулат, Dulat, lit. 'ruthless or fierce warrior'; Mongolian: Dolood/sevens, Doloo/seven; Middle Mongolian: Doluga, Dolugad; Dulğat; Chinese: 杜格拉特) was a Mongol (later Turko-Mongol) clan that served the Chagatai khans as hereditary vassal rulers of several cities in western Tarim Basin, in modern Xinjiang, from the 14th century until the 16th century. The most famous member of the clan, Mirza Muhammad Haidar, was a military adventurer, historian, and the ruler of Kashmir (1541–1551). His historical work, the Tarikh-i Rashidi, provides much of the information known about the family.
