Margraviate of Meissen
When in 1221 Louis' Wettin brother-in-law, Margrave Theodoric I of Meissen died, he acted as a guardian for Theodoric's minor son Henry III. However, his attempts to occupy the Meissen and Lusatian lands were rejected by his sister Jutta. Like his father, Louis was in close contact with the Hohenstaufen emperor Frederick II, who appointed him a Marshal of the Holy Roman Empire and confirmed his rights in the Margraviate of Meissen.
