The Warmiak are a Polish ethnic group from Warmia who are mostly Roman Catholics. Between the 14th and 17th centuries, settlers from northern Mazovia moved to former territories of Old Prussians, following conquests by the Teutonic Order, and the erection of the Monastic state of the Teutonic Knights. The bishopric of Warmia became in 1466 an autonomous part of Royal Prussia, which soon led to a conflict with Poland. While Mazurs in the neighboring Ducal Prussia became Protestants when that Duchy adopted Lutheranism in the 16th century, most Warmiaks, populating the areas around Allenstein (Olsztyn), remained Catholics.
