Elizabeth the Cuman
Elizabeth the Cuman (1240–1290/1295) was queen consort of Stephen V of Hungary and regent for her son Ladislaus IV. A Cuman chieftain's daughter, traditionally held to be Khan Köten, she was betrothed to Stephen, eldest son of Béla IV, sealing an agreement that gave the Cumans asylum in return for conversion and loyalty.
When Stephen V died in 1272, she ruled Hungary as regent during Ladislaus IV's minority until 1277. Her daughters Anna and Maria married Andronikos II and Charles II of Naples.
