with Bavaria. Salzburg was integrated into the Province of Salzach and Salzburgerland was ruled from Linz. In 1850, Salzburg's status was restored as the capital of the Duchy of Salzburg, a crownland of the Austrian Empire. The city became part of Austria-Hungary in 1866 as the capital of a crownland of the Austrian Empire. The nostalgia of the Romantic Era led to increased tourism. In 1892, a funicular was installed to facilitate tourism to Hohensalzburg Fortress. 20th century First Republic Following World War I and the dissolution of the Austro-Hungarian Empire, Salzburg, as the capital of one of the Austro-Hungarian territories, became part of the new German Austria. In 1918, it represented the residual German-speaking territories of the Austrian heartlands. This was replaced by the First Austrian Republic in 1919, after the Treaty of Saint-Germain-en-Laye (1919). Annexation by the Third Reich The Anschluss (the occupation and annexation of Austria, including Salzburg, into the Third Reich) took place on 12 March 1938, one day before a scheduled referendum on Austria's independence. German troops moved into the city. Political opponents, Jewish citizens and other minorities were subsequently arrested and deported to concentration camps. The synagogue was destroyed. After Germany invaded the Soviet Union, several POW camps for prisoners from the Soviet Union and other enemy nations were organized in the city. During the Nazi occupation, a Romani camp was built in Salzburg-Maxglan. It was an Arbeitserziehungslager (work 'education' camp), which provided slave labor to local industry. It also operated as a Zwischenlager (transit camp), holding Roma before their deportation to German camps or ghettos in German-occupied territories in eastern Europe. World War II Allied bombing destroyed 7,600 houses and killed 550 inhabitants. Fifteen air strikes destroyed 46 percent of the city's buildings, especially those around Salzburg railway station. Although the town's bridges and the dome of the cathedral were destroyed, much of its Baroque architecture remained intact. As a result, Salzburg is one of the few remaining examples of a town of its style. American troops entered the city on 5 May 1945 and it became the centre of the American-occupied area in Austria. Several displaced persons camps were established in Salzburgamong them Riedenburg, Camp Herzl (Franz-Josefs-Kaserne), Camp Mülln, Bet Bialik, Bet Trumpeldor, and New Palestine. Today After World War II, Salzburg became the capital city of the Federal State of Salzburg (Land Salzburg) and saw the Americans leave the area once
