The Cumans, also known as Polovtsy (Slavic for yellowish) were a nomadic West Turkic tribe living on the north of the Black Sea along the Volga. They are identified with the Western branch of the Kipchaks.
The Cumans and the Tatars were nomadic warriors of the Eurasian steppe who exerted an enduring impact on the medieval Balkans.
As a consequence, groups of the Cumans and the Tatars settled and mingled with the local population in various regions of the Balkans.
From 1091 the Cumans gained the upper hand in the Balkans, and their role in the re-establishment of the Bulgarian Empire in 1185–6 and in its eventual fate was fundamental.
Cumans, also called as Polovtsy, (Russian Половцы, from old Slavic for pale yellowish) was the European name for the Western Kipchaks, a nomadic West Turkic tribe living on the north of the Black Sea along the Volga.
Cumans having settled in Hungary had their own self-government there, and their name (kun) is still preserved in the county names Bács-Kiskun and Jász-Nagykun-Szolnok, and town names as (eg.) Kiskunhalas, Kiskunszentmiklós as well.
