Papal legate
On the threshold of his reign, Bolko II fell into conflict with the Church. The continued financial difficulties of the Duke lead him to invade and steal goods from the monasteries of and Kamieniec Ząbkowicki. In 1329, the Duke attacked the suite of the Papal legate Pietro di Alverni. This action motivated the intervention of the Kings of Poland and Bohemia, with the support of almost all of the Silesian dukes. Defeated, Bolko II was excommunicated by the Bishop of Wrocław, Nanker. The excommunication was only removed after Bolko II paid large sums to both the Papal legate and the monasteries as compensation.
