The sources record the only mention of this princess: in 1297 she was married to the son of Daniil Alexandrovich, Yuri Danilovich [I, cl. 484; 5, p. 128]. Apparently, the marriage was concluded when Yuri himself was at most 14 years old [2, p. 46]. Probably, his wife was of the same age or slightly younger. Such a hasty marriage of the eldest son, who had barely reached the age of majority, is explained by the intense struggle between the sons of Alexander Yaroslavich Nevsky, the middle Andrei Alexandrovich and the younger Daniil. For Daniil Alexandrovich, the search for allies was especially relevant, since Andrei was supported by Khan Toqta [1, p. 24-28]. Anna's father, Prince Konstantin Borisovich of Rostov, had also previously sided with Andrei and in the early 1280s took part in the Tatars' campaigns against Murom and Pereyaslavl [ibid.], supported by Daniil Alexandrovich. Apparently, Yuri's marriage was supposed to consolidate this union. It is known about one daughter of the prince, the wife of Konstantin Mikhailovich of Tver [II, cl. 41; 3, p. 10; 4, p. 128]. The fate of the princess is unknown. In 1317, Prince Yuri Danilovich remarried to Konchaka, the daughter of the Tatar Khan [6, p. 63]. It can be assumed that by 1317 Anna was no longer alive.
