Czechoslovakia was an independent country in 1938. It was formed in 1918 after the First World War with international agreement. Hitler wanted "Lebensraum" (meaning "living space"), which would have all Germans in Czechoslovakia united with Germany. As most German-speakers in Czechoslovakia were in the Sudetenland, Hitler set his sights there first. He knew that most of the industrial strength of Czechoslovakia would be lost with the Sudetenland leaving Czechoslovakia. Britain, France and the Soviet Union had all agreed to support Czechoslovakia if it was invaded.
