Conquests

The Cumans entered the grasslands of the present-day southern Russian steppe in the 11th century AD and went on to assault the Byzantine Empire, the Kingdom of Hungary, the Principality of Pereyaslavl and Kievan Rus'. The Cumans' entry into the area pressed the Oghuz Turks to shift west, which in turn caused the Pechenegs to move to the west of the Dnieper River. Cuman and Rus' attacks contributed to the departure of the Oghuz from the steppes north of the Black Sea. Mahmud al-Kashgari, writing in 1076, says that in the east Cuman territory bordered a town near Talas. The Cumans first entered the Bugeac (Bessarabia) at some point around 1068–1078. They launched a joint expedition with the Pechenegs against Adrianople in 1078. During that same year the Cumans were also fighting the Rus'. The Russian Primary Chronicle mentions Yemek Cumans who were active in the region of Volga Bulgaria.
