The Cuman entered the steppes of modern-day Kazakhstan around the early 11th century, where they later joined with the Kipchak and established the vast Cuman-Kipchak confederation. While ancient cities Taraz (Aulie-Ata) and Hazrat-e Turkestan had long served as important way-stations along the Silk Road connecting Asia and Europe, true political consolidation began only with the Mongol rule of the early 13th century. Under the Mongol Empire, first strictly structured administrative districts (Ulus) were established.
