Masurian (Polish: Mazurski; German: Masurisch) was a dialect group of the Polish language, spoken by Masurians in a part of East Prussia that belongs to today's Poland. Masurians are regarded as being descendants of Masovians.
Since the 14th century, some settlers from Masovia started to settle in southern Prussia, which had been devastated by the crusades of the Teutonic Knights against the native Old Prussians. According to other sources, people from Masovia did not move to southern Prussia until the time of the Protestant Reformation, Prussia having become Lutheran in 1525. The Masurians were mostly of the Protestant faith, in contrast to the neighboring Roman Catholic people of the Duchy of Masovia, which was incorporated into the Polish kingdom in 1526. A new dialect developed in Prussia, isolated from the remaining Polish language area. The Masurian dialect group has many Low Saxon, German and Old Prussian words mixed in with Polish-language endings.
Beginning in the 1870s, Imperial German officials restricted the usage of languages other than German in Prussia's eastern provinces. While in 1880 Masurians were still treated as Poles by German Empire, at the turn of century the German authorities undertook several measures to Germanise and separate them from the Polish nation by creating a separate identity. After World War I the East Prussian plebiscite was held on July 11, 1920 according to the Treaty of Versailles, in which the Masurians had to decide whether they wanted to be part of the Second Polish Republic or remain in German East Prussia; about 98% voted for Germany.
By the early 20th century, most Masurians were at least bilingual and could speak Low Saxon and German; in some areas about half of them still spoke Masurian, at least at home. In 1925, only 40,869 people gave Masurian as their native tongue, many considering German their first language, considering Masurian merely as their domestic dialect. In the early 1930s, support for the Nazi Party was high in Masuria, especially in elections in 1932 and 1933. Nazi political rallies were organized in the Masurian dialect during the campaigning.
The replacement of Masurian in favor of German was not completed by the time the Soviet Red Army conquered Masurian East Prussia in January 1945, in World War II. The territory was transferred to Poland according to the postwar Potsdam Conference. During the wartime fighting and post-war deportations in the subsequent decades, most Masurian-speakers left Masuria for western Germany, especially to post-war West Germany, where they were quickly assimilated into the German mainstream. As a result the Masurian dialect virtually died out.
