Maximilian I pronounced the ban of the Holy Roman Empire on the
Elector Palatine's son Rupurt for seizing Landshut. Rupert was
married to the daughter of the late Duke George of Bavaria-Landshut
had left the territory to his daughter, Rupert's wife, but this
legacy contravened a succession agreement previously made between
the duchies of Bavaria-Landshut and Bavaria-Munich. As a result,
this issue prompted military campaigns in South Germany.
