What is studetenland?

Answer 1

Spelling! Sudetenland. The Sudetenland was part of Germany until 1806 and of the German Confederation between 1815 and 1866. After WWI and under the terms of the Treaty of Versailles the Sudetenland (some 11,000 square miles) became part of Czechoslovakia. As this was a German-speaking area, Hitler naturally claimed it for the Third Reich. The German annexation of the Sudetenland was what was agreed to at Munich in 1938. What Chamberlain and the Allies should have noticed was that the Sudetenland included nearly all Czechoslovakia's defensive works on the German border. Once it was occupied, the taking of the remainder of the country was a mere formality.
