Wratislaus of Brno (Czech: Vratislav Brněnský, German: Wratislaus von Brünn, Latin: Wratislaus Brunensis; died August/September 1156) was the Duke of Moravia from 1125 to 1129 and from 1130 to 1156. He was the first son and successor of Ulrich I, Duke of Brno (died 1092) and an unknown princess (probably of Slavic origin). He did not succeed as half monarch of Moravia (diarch), for all half of Moravia (the west one) as his father Ulrich I, but Brno was already divided into two parts (Brno and Znojmo) and his father Ulrich was co-monarch with his uncle Luitpold of Znojmo in this part.[1] [2] Both brothers together later established a Benedictine monastery and its St. Procopius Basilica in Třebíč and prepared as mausoleum for the Brno-Znojmo branch House of Přemyslid. Wratislaus himself probably initiated the establishment of the Royal cathedral chapter of St. Peter and Paul in Brno, formally created later in 1292.He reigned over Moravia (as diarch in Brno), once interrupted (1128–1130) by an illegitimate regency of Soběslav I). By his marriage in 1132 to a Russian princess, he probably had two or possibly three children:
He was succeeded legitimately as prince of Brno by his son Spitihněv of Brno (1146).
Wratislaus initially ruled in the Brno part (the western one) of the duchy of Moravia, until 1129 when they were evicted illegitimately by Bretislaus II. Later (1130) they enforced a return of the Brno part of the Moravian duchy - 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 union. In 1104 his father and uncle together founded a Benedictine abbey in Třebíč whose convent church of St. Procopius was intended as their own dynastic mausoleum where they were both buried.
Moravian lines of Přemysl dynasty as a whole were systematically associated with dynastic marriages with princesses of major royal and ducal dynasties, members of Brno line were associated Rurik dynasty, specially Wratislaus was 1132 spoused with princess of House of Rurik 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.
