After returning from his pilgrimage he had the idea of founding a monastery of regular canons in Prague, which would materialize as Strahov Monastery. Zdík had the support of the bishops of Prague, the Duke of Bohemia Soběslav I, and — after his death — Vladislav II. After Zdík's first unsuccessful attempt to found a Czech variant of the canons' order at the place called Strahov in 1140, an invitation was issued to the Premonstratensians, whose first representatives arrived from Steinfeld in the Rhine valley (Germany).
