Instead, Luitpold ruled in half of Moravia (the western part) as had his father Conrad I, though again the territory was divided into two principalities: Brno and Znojmo.

Luitpold ruled over southern Moravia as diarch in Znojmo for 20 years, only once interrupted by the illegitimate regency of Duke Bretislav II in 1099–1100, when he and Ulrich were evicted.

He had Ulrich captured and arrested in Kladsko, while Luitpold fought against the forces of Bořivoj's father-in-law, the Babenberg margrave Leopold II of Austria.

Henry IV gave Ulrich insignia of rank and banner (vexillum) for their reign as Moravian dukes, while Luitpold's brother officially renounced all claims to the Prague throne.

About 1101, Luitpold and Ulrich together established the Benedictine abbey of Třebíč and prepared its St. Procopius Church as a mausoleum for the Brno-Znojmo branch of the Přemyslid dynasty, where they were both later buried.
