What was the annexation of Czechoslovakia?
In September 1938 the German chancellor Adolf Hitler had already united Austria to Germany and wanted to bring the Sudeten Germans under his rule. The mountains surrounding Bohemia (the Czech part of Czechoslovakia) were populated by ethnic Germans but the boundary was drawn in favor of the Czechs for defensive purposes. The British and French premiers met Hitler in Munich and agreed to the change of boundary, and the Sudetenland was annexed to Germany. But in March 1939 Hitler then occupied Bohemia and Moravia as a protectorate (not annexed), Slovakia was nominally made independent but its government was protected by Germany, and Ruthenia, the easternmost part of Czechoslovakia, was annexed to Hungary.
