Together with his cousin Albert IV of Bavaria-Munich George tried to extend his influence in Further Austria, but in 1489 he abandoned these plans to settle the difference with Frederick III, Holy Roman Emperor.

[3] George later became a strong ally of Emperor Maximilian I and supported his campaigns in Swabia, Switzerland, Geldern and Hungary.

[5] However, none of their sons survived until George's death, and per the restrictions of the Salic law practiced in medieval Germany, their daughters could not inherit the duchy.

Only the new duchy of Palatinate-Neuburg passed to Ruprecht's sons Otto-Henry, Elector Palatine (Ottheinrich) and Philip.

The most southern districts of Bavaria-Landshut Kufstein, Kitzbühel and Rattenberg passed to Emperor Maximilian and were united with Tyrol.
