The Kipchak (also spelled Qipchaq, Kypchak, Kupchak or Kipçak) were a Turkic nomadic people. Originating in the Kimek Khanate, they conquered large parts of the Eurasian steppe during the Turkic expansion of the 11th and 12th centuries together with the Cumans, and were in turn conquered by the Mongol invasions of the early 13th century. The Cuman-Kipchak confederation was a predecessor of the Kazakh Khanate and, later, modern-day Kazakhstan.
