Wie trouwde met Maria of Masovia?

Maria of Masovia (pl: Maria mazowiecka; 1408/15–14 February 1454) was a Duchess of Pomerania by marriage to Bogislaw IX, Duke of Pomerania, and regent of Pomerania from 1446 to 1449.

Bogislav IX (German: Bogislaw IX., Polish: Bogusław IX; 1407/1410 – 7 December 1446), was a duke of Pomerania in Pomerania-Stolp, whose residence was Stargard. In 1439 his first cousin Eric of Pomerania tried in vain to have him recognised as Erik's heir to the Kalmar Union.

Bogislav was the son of Bogislav VIII, Duke of Pomerania, and Sophia of Holstein. On 24 June 1432, in Poznan, he married Maria of Masovia, daughter of Siemowit IV, Duke of Masovia and Alexandra of Lithuania. They had daughters, Sophia, who married Eric II, Duke of Pomerania, and Alexandra, and at least one of unknown name.

During the Polish–Teutonic War (1431–1435), Bogislav opposed the Teutonic Knights and supported the Kingdom of Poland. He was later involved in struggles related to Pomeranian bishops.

Upon his death in 1446, Bogislav IX was succeeded in Pomerania-Stolp by Eric of Pomerania, who ruled as "Erik I".
