The author proposed only some hypothesis that can be regarded as starting point for further research. The creation of the bishopric of Wrocław as an administrative and organisational unit preceded and quickened consolidation of the state. It played a sigificant role in a process of integration. The structure of the bishopric corresponded with the divisions made by the state what could lead to disintegration, but it was not of such a decisive role. Bishop himself was a leading person among local dukes. He reached such a politival position that could influence events beyond the region’s borders. During the first phase he consolidated the region with the Polish authorities. During the second phase he emancipated himself as a duke. During the third phase he became a leader of local dukes and a main supporter of the Bohemian authorities. At late Middle Ages, supported by curia, he fought against the Bohemian King-heretic. Subordinating of the bishopric to metropolitan bishop in Gniezno was not followed by disintegration within the Bohemian Crown, though it was the way to balance the pressure experienced by the Silesian church hierarchy from the King of Bohemia. The church orders came to Silesia from outside and lots of them were connected with foreign centres originally and in contemporary activity. Gradually, however, they put down new roots in the region, and contributed to its territorial safety (by colonization and confirming the borders), forming its identity (by monastic historiography) and political attitudes (especially during the critical period of schism and religious wars).
