Euphrosyne Yaroslavna

Euphrosyne Yaroslavna was a Galician princess, the daughter of Prince Yaroslav Osmomysl of Halych and Olga Yurievna of Suzdal. Her personal name is absent from the chronicles and the attribution remains uncertain. Around 1169 she married Prince Igor Svyatoslavich of Novgorod-Seversk and bore him six children.

She is famous as the Yaroslavna of The Lay of Igor's Campaign, about Igor's failed 1185 raid against the Polovtsians; her Yaroslavna's Lament, in which she pleads with the Dnieper for her husband's return, is one of the poem's most celebrated passages and made her the emblem of the faithful wife.
