Yevdokiya Borisovna Yusupova (; May 5 (NS: May 16) 1743, Moscow – July 19 (NS: July 8) 1780, Saint Petersburg), was a Duchess consort of Courland. She married the Duke of Courland, Peter von Biron, on March 6, 1774 in Mitau. She had no issue. Biography Yevdokiya Yusupova was the eldest daughter of Prince Boris Grigoryevich Yusupov and Irina Mikhaylovna Zinovyeva. The marriage was arranged by empress Catherine II of Russia to secure a good relationship between Russia and Courland. Courland Duke Peter was described as wild, and Yevdokiya Yusupova was regarded as a beauty with spiritual qualities. She became popular among the nobility in Courland and did succeed in her task to recruit Pro-Russians among the Courland nobility. Initially, she also managed to wield some influence over Duke Peter. The relationship between Yusupova and Peter soon deteriorated, however, and she wished to be freed from the abuse he is reported to have treated her with.
