Ursula of Brandenburg, Duchess of Münsterberg-Oels

Ursula of Brandenburg (25 September 1450 – 25 November 1508, Breslau) was a princess of Brandenburg by birth and by marriage Duchess of Münsterberg and Oels and Countess of Glatz.

Life
Ursula was the eldest child of the Elector Albrecht Achilles of Brandenburg (1414–1486) from his first marriage to Margarete of Baden (1431–1457). The princess was considered a favorite child of her father and one of the most prominent victims of the marriage of convenience in the 15th century. First, she had been promised to Duke Albert the Brave of Saxony. When he broke off the engagement, she was passed on to his older brother, Ernest. When this engagement was also dissolved, the next marriage candidate was Duke Henry the Elder of Münsterberg-Oels (1448–1498), son of the Bohemian king George of Poděbrady. In 1466 Pope Paul II disapproved of the engagement as a "blasphemous connection with a heretic", and Ursula and her father were excommunicated. The relations between Brandenburg and Emperor Frederick III also worsened due to the engagement. George of Poděbrady and Abrecht Achilles created a defensive alliance against all the opponents of the marriage.

Without telling her father, Ursula secretly became engaged to Count Rudolph III of Sulz, Landgrave in Klettgau. The pope dissolved this engagement, and she eventually married in Cheb (Eger), on 9 February 1467, Duke Henry the Elder of Münsterberg. The ban imposed on Ursula and her father was lifted in 1471.
