Louis invaded the imperial free cities of Dinkelsbühl and Donauwörth in 1458, and disputed with Frederick III, Holy Roman Emperor until peace was made in Prague in 1463.

In 1475 he organized the Landshut Wedding of his son George with the princess Hedwig Jagiellon, a daughter of King Casimir IV of Poland.
