The Golden Horde (, Altan Ordu, Зүчийн улс, Züchii-in Uls; ; ) was a Mongol and later Turkicized khanate established in the 13th century and originating as the northwestern sector of the Mongol Empire. With the fragmentation of the Mongol Empire after 1259 it became a functionally separate khanate. It is also known as the Kipchak Khanate or as the Ulus of Jochi.
