The name Cumania originated as the Latin exonym for the Cuman-Kipchak confederation, which was a Turkic confederation in the western part of the Eurasian Steppe, between the 10th and 13th centuries. The confederation was dominated by two Turkic nomadic tribes: the Cumans (also known as the Polovtsians or Folban) and the Kipchaks. Cumania was known in Islamic sources as Desht-i Qipchaq, which means "Steppe of the Kipchaks"; or "foreign land sheltering the Kipchaks", in the Turkic languages. Some Russian sources have referred to Cumania as the "Polovtsian Steppe" (Poloveckaja Step), or the "Polovcian Plain" (Pole Poloveckoe).
