The daughter of a Byzantine Emperor – the wife of a Galician-Volhynian Prince
The daughter of a Byzantine Emperor – the wife of a Galician-Volhynian Prince

Summary/Abstract: The military aid that Galician-Volhynian prince Roman Mstislavich rendered to Byzantine Emperor Alexios III was guaranteed by Roman’s marriage to the niece of Alexios III, the elder daughter of the overthrown emperor Isaak II. She became Roman’s second wife and for years played the key role in the political life of Southern Rus’. The chronicle did not preserve the name of the princess who is called by her husband’s name only as “Roman’s Grand Princess”. However, this gap can be filled. Irene, the junior sister of the Galician-Volhynian princess, who became the consort of the German King Philip, entered her sister’s name into the commemoration book of the Speyer Cathedral. Among Queen Irene’s other Greek relatives, the book mentions the name of her elder sister Euphrosyne.
