Life.
Frederick was the only son of the Wettin margrave Theodoric of Landsberg and Helene, a daughter of Margrave John I of
. However, Albert's sons Frederick the Bitten and Theodoric IV disputed this arrangement and Frederick's rule in Lusatia within short time was contested by his cousin Theodoric IV.
