In the case of Henry III and Władysław, the cooperation between the brothers was a mutual agreement with few opportunities to frictions, as Władysław mainly stayed in the Bohemian capital Prague at the court of his maternal cousin King Ottokar II. His role in the undivided Duchy of Wrocław was limited to receive his rents; Henry III took under his hands all the government. Nevertheless, Władysław too issued numerous deeds and in 1261 he and his brother jointly vested the Wrocław citizens with Magdeburg rights. With the support of the Bohemian king, Władysław continued his spiritual career: about 1255 he became a provost at the cathedral chapter of the St Peter and Paul collegiate church in Vyšehrad (today a part of Prague) and thus was appointed Bohemian Royal Chancellor, a post exclusively reserved for the Vyšehrad provosts. The close alliance between the Silesian Piasts and the Přemyslid dynasty strengthened the ties between the lands of Silesia and Bohemia.
