The Masurians or Mazurs (Polish: Mazurzy; German: Masuren; Masurian: Mazurÿ), historically also known as Prussian Masurians (Polish: Mazurzy pruscy), are a Polish ethnic group originating from the region of Masuria, within the modern-day Warmian-Masurian Voivodeship, Poland. They number around 5,000 to 15,000 people. In the 2011 Polish census, 1,376 individuals declared themselves to be Masurian as either a first or a secondary identification. Before World War II and its post-war expulsions, Masurians used to be a more numerous ethnic group found in the southern parts of East Prussia for centuries. Today, most Masurians live in what is now modern-day Germany and elsewhere.
Masurians are mostly descendants of colonists from Mazovia who moved north. Some research also indicate the admixture of the remains of the Old Prussians. These settlers moved during the State of the Teutonic Order and the Duchy of Prussia in the midst of the Protestant Reformation. They spoke the Masurian dialects. Since the mid-19th century, High German was increasingly used among Masurians as opposed to Low German used by most of East Prussia's German population. Many Masurians were often bilingual in German and Polish languages. In the 19th century, the Masuria region of East Prussia was named after the Masurians.
Like most of the East Prussian population, they favored Protestantism and adopted Lutheranism in 1525 when Albert, Duke of Prussia secularized the duchy and converted. Roman Catholic Warmiaks and the original Masovians were not affected, as they inhabited parts that formally belonged to the Kingdom of Poland. After World War II, many Masurians were classified as "Germans" and therefore mostly expelled along with them or emigrated after 1956 from what was now Poland to post-war Germany. Although most of them left for the West, some also ended up in East Germany. Conclusion of the war and ensuing resettlements also saw an ethnic conflict between leaving Masurians and incoming Kurpie mainly on religious (Protestant–Catholic) grounds.
