Bretislaus II, who in 1092 had succeeded his uncle Conrad I as Duke of Bohemia, is a major enemy of paganism who works for the destruction of the old Slavic culture.

In 1097, he expels the Slavonic monks of the monastery in Sazava, founded in 1033 by Procopius.

Bretislaus also wishes to end the elective principle of succession and replace it with a type of seniorate as conceptualized by Bretislaus I: the eldest prince of the reigning family will hold Bohemia as sovereign over the entire state while the younger scions of the dynasty will rule as territorial dukes over the regions of Moravia.

This is to the benefit of his half-brother Borivoj II.

He invests Borivoj as duke of Brno in 1097, thus removing the sons of Conrad I from the succession.
