Bavaria-Munich () was a duchy that was a constituent state of the Holy Roman Empire from 1392 to 1505, ruled by the Wittelsbach dynasty. It was created after the division of the Bavarian inheritance in 1392, and was re-unified at the end of the War of the Succession of Landshut after the defeat of George the Rich. The dukes of the realm held court in Munich. It existed concurrently with Bavaria-Landshut and Bavaria-Ingolstadt.
After the death of Stephen II in 1375, his sons Stephen III, Frederick, and John II jointly ruled Bavaria-Landshut. After seventeen years, the brothers decided to formally divide their inheritance. John received Bavaria-Munich, Stephen received Bavaria-Ingolstadt, while Frederick kept what remained of Bavaria-Landshut.
During the Great War of the Lords, Munich-Bavaria was able to take Markt Schwaben and Ebersberg from Bavaria-Ingolstadt. In the Bratislava Award, the Straubing Lands were also granted to the duchy. As a result, large swathes of the Bavarian Forest were granted to the duchy.
After the death of the last duke of Bavaria-Ingolstadt in 1447, Bayern-Landshut took control of the territory, with Bayern-Munich receiving very little. The ruler of Bavaria-Landshut, George the Rich, had no male heir, and thus designated his daughter Elizabeth as his heir. However, this was in contravention of both Wittelsbach and Imperial succession law, and so Albert IV began the War of the Succession of Landshut. After Duke Albert's victory, the realm was once again referred to simply as the Duchy of Bavaria.
The next decade was characterised by conflict between Frederick's son Henry and Stephen's son Louis. Ludwig believed, like his father, that he had been disadvantaged by the inheritance, which eventually culminated in the Great War of the Lords. Ludwig hoped that he could use his military might in order to be duly compensated for the indignity his father had suffered at his allegedly meagre inheritance. Ernest and Wilhelm desperately sought to mediate between the two dukes, but eventually sided with the Landshuters in a settlement in 1410, which imposed a forced alliance between the two. However, they eventually shifted their support to Henry after he had been assaulted by Louis at the Council of Constance.
The Munich dukes won the confidence of Emperor Sigismund after William was appointed the protector of the Council of Basel. As a result, they successfully received territories in Lower Bavaria from the Bratislava Award of 1429. When William died, his son Adolf was merely a child, and thus the succession of Bavaria-Munich depended entirely upon Duke Albert of Bavaria-Munich. Albert's illegitimate liasons with the commoner Agnes Bernauer further complicated the issue, and so his father Ernest ordered her to be drowned in the Danube. This briefly caused Albert to side with Ludwig, although Albert later reconciled with his father, and married Anna of Brunswick-Grubenhagen.
