Background
Dorothea was a daughter of the Elector Frederick I of Brandenburg (1371–1440) from his marriage to Elisabeth (1383–1442), daughter of Duke Frederick of Bayern-Landshut.
Dorothea was a daughter of the Elector Frederick I of Brandenburg (1371–1440) from his marriage to Elisabeth (1383–1442), daughter of Duke Frederick of Bayern-Landshut.
Elizabeth"s brothers were Electors Frederick II and Albert Achilles, who successively ruled Brandenburg. In May 1432, Dorothea married Duke Henry IV of Mecklenburg (1417–1477). Margaret"s husband, Ernest Louis, however, had died shortly after the marriage.
When a dispute arose later between Brandenburg and Mecklenburg about the inheritance of the principality of Wenden, the family ties between Duke Henry and Elector Frederick made it easier to reach a settlement.
Henry IV died in 1477. After 1485 Dorothea lived, she lived as a nun in the Rehna convent.
She died in 1491 and was buried in the City Church of Saint James" Church and Saint Dionysius in Gadebusch. Her grave stone is marked with an incised drawing of the Duchess as a nun, crowned by a canopy.
