Muscovite–Lithuanian War in the context of "Barbara Zápolya"

Barbara Zápolya (Hungarian: Szapolyai Borbála, Lithuanian: Barbora Zapojajietė, 1495–1515) was Queen of Poland and Grand Duchess of Lithuania as the first wife of Sigismund I the Old from 1512 to 1515. Marriage to Barbara represented an alliance between Sigismund and the House of Zápolya against the Habsburgs in succession disputes over the throne to the Kingdom of Hungary. The alliance was short-lived as the renewed Muscovite–Lithuanian War forced Sigismund to look for Habsburg allies. The marriage was loving, but short. Barbara was the mother of Hedwig, Electress of Brandenburg, but died soon after the birth of her second daughter Anna.
