called Windish, from the Austrian German term Windisch 'Wend'. The largest group of Slovenes in the United States eventually settled in Cleveland, Ohio, and the surrounding area. The second-largest group settled in Chicago, principally on the Lower West Side. The American Slovenian Catholic Union (Ameriško slovenska katoliška enota) was founded as an organization to protect Slovene-American rights in Joliet, Illinois, southwest of Chicago, and in Cleveland. Today there are KSKJ branches all over the country offering life insurance and other services to Slovene-Americans. Freethinkers were centered around 18th and Racine Ave. in Chicago, where they founded the Slovene National Benefit Society; other Slovene immigrants went to southwestern Pennsylvania, southeastern Ohio and the state of West Virginia to work in the coal mines and lumber industry. Some Slovenes also went to the Pittsburgh or Youngstown, Ohio, areas, to work in the steel mills, as well as Minnesota's Iron Range, to work in the iron mines and also to Copper Country on the Keweenaw Peninsula of Michigan for copper mining. Many also went west to Rock Springs in Wyoming to work in the coal mines that supported the Union Pacific Railway. World War I There were more than 30,000 casualties among ethnic Slovenes during World War I because they were and still are inhabiting the territory where the Isonzo Front was fought. While the majority of them were drafted in the Austro-Hungarian Army, also Slovene civil inhabitants from the Gorizia and Gradisca region suffered in hundreds of thousands because they were resettled in refugee camps where, however, Slovene refugees were treated as state enemies by Italians and several thousands died of malnutrition in Italian refugee camps. Fascist Italianization of Littoral Slovenes After the First World War (1914–1918), the majority of Slovenes joined other South Slavs in the State of Slovenes, Croats and Serbs, followed by the Kingdom of Serbs, Croats and Slovenes, and finally the Kingdom of Yugoslavia. In the new system of banovinas (since 1929), Slovenes formed a majority in the Drava Banovina. In the ex-Austrian Empire area given to Italy in exchange for joining Great Britain in World War I, the forced Fascist Italianization of Slovene minority in Italy (1920–1947) was under no international restraint especially after Benito Mussolini came to power in 1922. Already during the period of Italian occupation, between the years 1918 and 1920, all Slovene cultural associations (Sokol, "reading rooms" etc.) had been forbidden Fascist Italy
