Germans in Czechoslovakia (1918–1938)

The German-speaking population in the interwar Czechoslovak Republic, 23.6% of the population at the 1921 census, usually refers to the Sudeten Germans, although there were other German ethno-linguistic enclaves elsewhere in Czechoslovakia (e.g. Hauerland or Zips) inhabited by Carpathian Germans (including Zipser Germans or Zipser Saxons), and among the German-speaking urban dwellers there were ethnic Germans and/or Austrians as well as German-speaking Jews.
