Career
As Bishop, he advocated extensively on behalf of the church in the political sphere. Notably, Thomas was involved for years in a violent dispute with Duke Henry IV as to the prerogatives of the Church in Silesia, and was forced to leave Wrocław in 1285 and seek refuge with Prince Mieszko in Raciborz. In 1287 a reconciliation was effected between them at Regensburg, and in 1288 the duke founded the collegiate Church of the Holy Cross at Wrocław as part of the reconciliation.
Before his death, on the Eve of Saint John in 1290, the duke confirmed the rights of the Church to sovereignty over the territories of Neisse and Otmuchów making Thomas the first Prince-Bishop in Wrocław.
