The Investiture Controversy impending, Pope Victor II sought the alliance of the Bohemian duke. Thus, Rome granted the right to Spytihnev of wearing the mitre and tunic of a bishop for the annual sum of 100 marks. His brothers having inherited Moravia, Spytihnev tried to reduce their authority by arresting 300 Moravian magnates and stripping his brothers of their rights in the province. Thus, Vratislaus of Olomouc fled to Hungary in 1058.
Spytihnev was succeeded by Vratislaus, who in turn entrusted Moravia to his brother Conrad. His son Swatobor entered the church and became Patriarch of Aquileia.
