Margaret of Brandenburg (1450–1489)

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.[1] 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.[2] 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.[3] During the 1479 peace negotiations, Bogislaw finally signed away his wife's dower.
