Bavarians (Bavarian: Boarn, Standard German: Bayern) are an ethnographic group of Germans of the Bavaria region, a state within Germany. The group's dialect or speech is known as the Bavarian language, native to Altbayern ("Old Bavaria"), roughly the territory of the Electorate of Bavaria in the 17th century.
Like the neighboring Swabians and Austrians, Bavarians are traditionally Catholic. In much of Altbayern, membership in the Catholic church remains above 70%, and the center-right Christian Social Union in Bavaria (successor of the Bavarian People's Party of 1919–1933) has traditionally been the strongest party in the Landtag, and also the party of all Ministers-President of Bavaria since 1946, with the single exception of Wilhelm Hoegner, 1954–1957.
There is no ethno-linguistic distinction between Bavarians and Austrians. The territory of Bavaria has changed significantly over German history; in the 19th century the Kingdom of Bavaria acquired substantial territories of Franconia and Swabia, while having to return territories to Austria who had become Bavarian only a few years earlier. Thus, only three of the seven administrative regions of the state of Bavaria are culturally Bavarian: Upper Bavaria (Oberbayern), Lower Bavaria (Niederbayern) and the Upper Palatinate (Oberpfalz), to the exclusion of Bavarian Franconia (historically inhabited by Franks) and Bavarian Swabia (inhabited by Swabians).
