Vratislaus II of Bohemia
Conrad came to power over Moravia gradually. King Vratislaus II of Bohemia naturally did not like it and besieged Brno in 1091. But it came to rebellion in the royal army, led by King's son Břetislaus. Wirpirk, reputedly on her own initiative, went to Vratislaus camp and asked for quarter for her husband and nephew.
