Kunigunda of Halych

Kunigunda Rostislavna was Queen consort of Bohemia and its Regent from 1278 until her death. She was a member of the House of Chernigov, and a daughter of Rostislav Mikhailovich.

She was presumably born in Ruthenia, in the domains of her paternal grandfather Michael of Chernigov. Her grandfather was the last Grand Prince of Kiev, who was deposed not by a more powerful prince but by the Mongol Empire. Her parents were Rostislav Mikhailovich, future ruler of Belgrade and Slavonia, and his wife Anna of Hungary. After the death of her fathers father, Kunigundas family relocated to Hungary, where her mothers father, Bela IV of Hungary, made her father governor of certain Serbianspeaking regions in the Danube Valley. Her father proclaimed himself Emperor of Bulgaria in 1256 but did not stay there to defend his title.
