The German occupation of Czechoslovakia (1938 -- 1945) began with the German annexation of Czechoslovakia 's northern and western border regions, formerly being part of German - Austria known collectively as the Sudetenland, under terms outlined by the Munich Agreement. German leader Adolf Hitler 's pretext for this action was the alleged privations suffered by the ethnic German population living in those regions. New and extensive Czechoslovak border fortifications were also located in the same area.
