Who married Albrecht III Achilles, Elector of Brandenburg?

Albrecht III (9 November 1414 – 11 March 1486) was Elector of Brandenburg from 1471 until his death, the third from the House of Hohenzollern. A member of the Order of the Swan, he received the cognomen Achilles because of his knightly qualities and virtues. He also ruled in the Franconian principalities of Ansbach from 1440 and Kulmbach from 1464 (as Albrecht I).

Margaret of Baden (1431 – 24 October 1457) was a Margravine of Baden by birth and by marriage Margravine of Brandenburg-Ansbach and Brandenburg-Kulmbach. She was the daughter of Jacob, Margrave of Baden-Baden, and his wife Catherine of Lorraine.

In 1446, Margaret married Albert of Brandenburg, the future Albert III Achilles, Elector of Brandenburg, in Heilsbronn. Margaret died before he succeeded to the Electorate of Brandenburg, thus never served as Electress. Their marriage produced three sons and three daughters:

• Ursula (1450–1508)

married in 1467 Duke Henry I of Münsterberg-Oels (1448-1498)

• Elisabeth (1451–1524)

married in 1467 Duke Eberhard II of Württemberg (1447-1504)

• Margaret (1453–1509), abbess of the Poor Clares convent at Hof from 1476
• John Cicero (1455–1499), Elector of Brandenburg

Margaret died in Ansbach in 1457 shortly after her husband acquired the Margraviate of Brandenburg-Kulmbach.

Anna of Saxony (7 March 1437 – 31 October 1512) was a princess of Saxony by birth and an Electress of Brandenburg by her marriage to Albrecht III Achilles, Elector of Brandenburg.
