Kunság (German: Kumanien; Latin: Cumania), later also known as Jászkunság or Jászkun kerület (lit. "Jassic–Cuman District"), is a historical, ethnographic and geographical region in Hungary, corresponding to a former political entity created by and for the Cumans or Kuns. It is currently divided between the counties of Bács-Kiskun and Jász-Nagykun-Szolnok; these correspond roughly to two distinct traditional entities, Little Cumania and Greater Cumania, which are longitudinally separated by the Tisza. Kunság and its subdivisions were first organized by the Kingdom of Hungary to accommodate semi-nomadic Cumans escaping from the Mongol Empire. The Cuman enclaves were sometimes incorporated with Jazygia, which was similarly set up and named for Ossetian nomads.
Kunság was the result of a second and final Cuman colonization in Hungary; while not the only Cuman-inhabited area, it remained the only centre of Cuman self-rule after the end of Arpadian Hungary. Tradition dates its emergence to 1279, when Ladislaus IV, a half-Cuman King of Hungary, granted its first set of fiscal and judicial privileges. These were confirmed in the 15th century, when Cumans began organizing themselves into "seats" overseen by a Palatine of the Kingdom. However, the consolidation of feudalism created dissatisfaction across the region, leading to its participation in György Dózsa's uprising of 1514.
