Divorce and second marriage of Knyaz Roman Mstislavich

The paper focuses on a family conflict at the turn of XIIXIII centuries between the Kievan Knyaz Rurik Rostislavich and the Galician Knyaz Roman Mstislavich, who married Ruriks daughter Predslava. In historiography the problem is one of the most controversial, since it is directly related to the dating of the second marriage and the origin of the second wife of Roman Mstislavich. The author, on the basis of available data, tried to determine the chronology of events, as well as to show close family relations between the knyazes of Rurik dynasty and the policy. The political conflict between Roman and his father-in-law Rurik Rostislavich, together with other reasons, led to the termination of his family relations with his daughter. The key topic in the paper is the probable mechanism of Galician knyaz second marriage legitimation, which allowed him to divorce his first wife and get married for the second time. According to the author, divorce from Predslava was not a one-time act for Roman Mstislavich. Despite the church divorce received from the Patriarch of Constantinople, the Galician knyaz went to the violent tonsure of his first wife to finally legitimize his new family life and children from his second marriage.
