Maria Mstislavna of Kiev
Her marriage was arranged in 1116 to facilitate better relations between her father and spouse, who were long standing enemies. During the reign of her spouse, she was known for her diplomatic ability, and often asked to mediate between her husband and brothers. She is believed to be one of the founders of St. Cyril's Monastery.
