Wratislaus of Brno information

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^{[clarification needed]} of Moravia (the west one) as his father Ulrich I^{[clarification needed]}, 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^{[clarification needed]} part.^[1][2] Both brothers^[who?] 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:

• Spytihněv of Brno (or)^{[clarification needed]}, Duke of Moravia from 1125 to 1129 and from 1130 to his death in 1146
• Svatopluk of Brno (?),(or) Prince of Jemnice (?)
• Agnes (?) 1197

He was succeeded legitimately as prince of Brno by his son Spitihněv of Brno (1146).
