Albert III, Duke of Bavaria

Albert was first engaged in 1429 to Elisabeth, the daughter of Eberhard III, Count of Württemberg, but she eloped and married Count John IV of Werdenberg, who had been a page at her father's court.

In 1432, while Albert was administrator on behalf of his father Ernest, Duke of Bavaria-Munich in the former duchy of Bavaria-Straubing, he secretly married Agnes Bernauer, a maid from Augsburg. His father was against this marriage. In 1435, when Agnes lived in Straubing, Duke Ernest ordered her to be murdered. She was accused of witchcraft, thrown into the Danube River and drowned while Albert was away hunting. After his first wife's death, Albert remained with Louis VII, Duke of Bavaria-Ingolstadt at Ingolstadt, but he reconciled with his father that November.

After reconciliation with his father, Albert married princess Anna of Brunswick-Grubenhagen-Einbeck as his second wife and had ten children with her.[2]

In 1438, Albert succeeded his father as duke of Bavaria-Munich. Around 1438-39, he built Blutenburg Castle between two arms of the River Würm into a hunting lodge. The castle was later extended by his third son Sigismund. In 1440, Albert refused the offered Bohemian crown. In 1442, he expelled the Jews from all Upper Bavarian territories. It was not until 250 years later that Jewish settlement was allowed again. In 1444 and 1445, he initiated two campaigns against the Robber barons. After the extinction of the dukes of Bavaria-Ingolstadt, Albert released this duchy to his father's cousin Henry XVI of Bavaria-Landshut in 1447.

In 1455, Albert founded the Benedictine monastery in Andechs. He died in Munich in 1460 and was buried in Andechs.

On 22 January 1437, in Munich, Albert married Anna of Brunswick-Grubenhagen-Einbeck,[1] daughter of Duke Eric I of Brunswick-Grubenhagen and Elisabeth of Brunswick-Göttingen and they had the following children:

1. John IV, Duke of Bavaria (4 October 1437, Munich–18 November 1463, Haidhausen).
2. Ernest (26 August 1438, Munich–29 February 1460, Straubing).
