Margaret was the second daughter of the Elector
Frederick II of Brandenburg (1413–1471) from his marriage to
Catherine (1421–1476), daughter of the Elector
Frederick I of Saxony. Only two of Frederick's four children survived him: Margaret and her older sister
Dorothea. She married on 20 September 1477 in
Prenzlau with Duke
Bogislaw X of Pomerania (1454–1523). In 1474, Brandenburg had begun a war against Pomerania, because Bogislaw refused to pay
homage to Frederick II. On 1 May 1476, during the peace negotiations, it had been decided that Bogislaw would marry Margaret. The marriage was burdensome on Bogislaw. A very low
dower had been agreed; even so, it was never paid. A year after the marriage, Bogislaw's uncle
Wartislaw X died, making Bogislaw the sole ruler of Pomerania in about 200 years. In 1479, Bogislaw concluded the
Peace of Prenzlau with his wife's uncle
Albert III Achilles, recognizing the Elector of Brandenburg as his
liege lord. Margaret's marriage was childless and her husband accused her of infidelity and disowned her. This led to political tensions with the
Electorate of Brandenburg. The elector demanded that her
dowry be returned. Bogislaw, in turn, alleged that the House of Hohenzollern had given him a barren princess for a wife, so as they would get to inherit Pomerania. During the 1479 peace negotiations, Bogislaw finally signed away his wife's dower. ==Ancestors==
