Anna (Lithuanian: Ona Vytautienė; died on 31 July 1418 in Trakai[1]) was Grand Duchess of Lithuania (1392–1418). She probably was the first wife of Vytautas the Great, Grand Duke of Lithuania. Anna was mother of Sophia of Lithuania, the wife of Vasily I of Moscow.[1] She is best remembered for helping Vytautas to escape from a prison in Kreva in 1382 and thus probably saving his life. Little is known about Anna's life and even her origins remain disputed by historians.
