At the beginning of the thirteenth century, the attempts to the Christianization of Prussia were resumed. The greatest and lasting results brought the Cistercian mission, led by the missionary bishop, Christian. The arrival of the Teutonic and DominicanOrders to Prussia changed the political, social and religious situation in this area dramatically. The Teutonic Order in the thirteenth century was dealing with creating their statehood and with the military conquest of the land. In converting the pagans, they were very glad to count on the assistance of the Dominican Order. The Dominican merits in the evangelism were so large that the Holy See was entrusting the priests from this Order with the most important ecclesiastical offices. By the end of the thirteenth century the Dominican Order gained in Prussia and also abroad the universal acclaim and respect, which raised objections and concerns of the Teutonic Order.
