Anna was one of the six daughters of the Hungarian king Bela IV [5, p. 128]. The exact year of her birth is unknown, but researchers propose 1226 as a possible date. During the struggle between Daniil Romanovich and Rostislav Mikhailovich, the son of Mikhail Vsevolodovich of Chernigov, Rostislav wooed Anna several times at the Halych court [3, p. 388]. Expelled to Hungary by the troops of Daniil of Halych, the prince hoped through this matrimonial union to enshure the support of the king to continue the struggle [2, p. 10]. Bela IV eventually agreed, and around 1244 Rostislav and Anna were married. Probably, the wedding itself, or rather the incident that occurred at that time, caused Rostislav to break up with his father Mikhail Vsevolodovich. The latter was not allowed to the feast by the army of Bela IV and, returning to Chernigov, disowned his son.
At first, Bela IV supported his son-in-law in his confrontation with Daniil, but after the latter returned from the Golden Horde as a fiefdom, the situation changed dramatically. As a guarantee of allied relations between Bela and Daniil, another daughter of King Constance and the son of the prince of Halych Lev Danilovich ware married [1, p. 49–55]. After this marriage, it is not possible tosuggest a full-scale Hungarian support for Rostislav. Rostislav received from his father-in-law the Bereg County and the Fuser castle, then the Banat of Slavonia. Anna became the baness of Slavonia and Masco. In a marriage with Rostislav, she had two sons and three daughters, who were later married to the Bulgarian and Bohemian kings. After Rostislav's death in 1262, Anna lived at her father's court. After the death of Bela IV, together with her daughter Kunigunda (Kunguta) and son-in-law Ottokar II, she was forced to flee to Bohemia to avoid the persecution of Istvan (later Istvan V) who claimed the Hungarian throne.
She died after 1274, the exact data on the last years of the princess's life have not been attested [4; 6].
There is a legend that after fleeing Hungary, Anna took to Bohemia part of the Hungarian treasury including the crown of St.Istvan.
