"Westphalia or Westfalia (/wstfeli/; German: Westfalen pronounced [vstfaln], Westphalian: Wäästfaln, Westfaoln) is a region in northwestern Germany, centered on the cities of Dortmund, Bielefeld, Münster and the town of Arnsberg. It is one of the three historic parts of the state of North Rhine-Westphalia. Westphalia is roughly the region in between the rivers Rhine and Weser, located both north and south of the Ruhr River. Although today Westphalia is almost exclusively referred to as the Westphalian (non-Rhenish) part of North Rhine-Westphalia, the term was applied to several different entities in history. Modern Westphalia consists of the Governmental Districts of Arnsberg and Münster and the Governmental District of Detmold with exception of the District of Lippe. The region has 20,208 km2 (7,802 sq mi) in land area, and 7.8 million inhabitants. The term Westphalia contrasts with the much less used term Eastphalia, which roughly covers the southeastern part of the present-day state of Lower Saxony, eastern Saxony-Anhalt and northern Thuringia. Westphalia's north is a part of the North German Plain. Its south has hills and mountains. Historically it was a Province of Prussia and was ruled by its Kings who were also the German Emperors until the abolition of monarchy in 1918. In 1946 it joined the newly created state of North Rhine-Westphalia together with the north of the former Prussian Rhine Province and with Lippe which used to be a separate Principality within Germany. A linguistic definition of Westphalia (see Westphalian language) excludes Siegen-Wittgenstein but includes Lippe, the County of Bentheim, the Osnabrück Land and the southern territories of the Oldenburg Münsterland and the Emsland. Westphalia is known for the 1648 Peace of Westphalia which ended the Thirty Years' War, as the two treaties were signed in Münster and Osnabrück. The region is also home to the headquarters of Westfalia-Werke, the contractor that built the Volkswagen Westfalia Campers."
