Ulrich I, Duke of Brno (, , ; 11th century â 5 January 1113) was the Duke of Moravia for twenty one years - between 1092 and 1113. He was the first son and successor of Conrad I, Duke of Bohemia (died 1092) and Wirpirk of Tengling. He did not succeed as half ruler of Moravia (diarch), for all half of Moravia (the west one) as his father Conrad I, but Brno was divided into two parts: Brno and Znojmo and Ulrich was co-ruler in this part with his brother Luitpold of Znojmo. Both brothers together established a benedictine cloister and its St. Procopius Basilica in Tà ÂebÃÂàand prepared as mausoleum for Brno-Znojmo branch House of Pà Âemyslid.
He had long ruled over Moravia (as diarch in Brno) for 21 years, once interrupted by illegitimate regency: (1099âÂÂ1100 by Bretislaus II)
By his marriage to an unknown princess, he probably had two children:
He was succeeded legitimately as prince of Brno by his son Wratislaus of Brno.
Ulrich and Luitpold initially ruled in the Brno part (the western one) of the duchy of Moravia, until 1099 when they were evicted illegitimately by Bretislaus II. Later they enforced a return of the Brno part of the Moravian duchy - with the help of the Bavarian armed troops as well as indirect support by Emperor Henry IV (whom he visited in early February 1101 in Frankfurt), according to the principles of agnatic seniority. After they returned to the duchy of Brno, the brothers divided it into two subparts named Brno (principality) and Znojmo (principality), where they continued to reign in certain local territorial unions. In 1104 they together founded a Benedictine abbey in TÃ ÂebÃÂÃÂ whose convent church of St. Procopius was intended as their own dynastic mausoleum where they were both buried.
Emperor Henry IV gave Ulrich insignia of rank and banner (vexillum) for their reign in the duchy.
All the Moravian lines of Pà Âemysl dynasty as a whole were systematically associated with dynastic marriages with princesses of major royal and ducal dynasties, especially ÃÂrpád dynasty, Rurik dynasty, Piast dynasty, Nemanjiàdynasty-senior line Vukanoviàand houses of bavarian monarchs, as it was the other way around (vice versa). Members of the Moravian dynasty were fully predisposed to take over the central throne (for both countries - Bohemia and Moravia) in Prague, under the principles of agnatic seniority.
