How was Czechoslovakia different from Austria when Hitler threatened Annexation?

Less than half a year after it was signed, Nazi Germany broke the Munich Pact. Germany invaded the Czech provinces of Bohemia and Moravia on the 15 March 1939.

Unlike with the Sudetenland, these provinces were not incorporated directly into the German Reich. They instead became known as the Protectorate of Bohemia and Moravia, and were placed under Nazi rule.

Following Nazi Germany’s move, Hungary soon made territorial claims on the south of what was formerly Czechoslovakia.

Slovakia, a province of Czechoslovakia, just above the Hungarian annexed zone, became an independent Catholic state with close links to Nazi Germany.

By the end of 1939, Czechoslovakia had completely disappeared from the map.

Despite breaking the Munich Pact almost immediately, Hitler did not face a military response from the Allies.
