On March 15, 1939, German troops moved into the remaining parts of Bohemia and Moravia, effectively completing the annexation of Czechoslovakia by Nazi Germany. This event marked a significant escalation toward World War II, as it demonstrated that Adolf Hitler's territorial ambitions extended beyond ethnic German regions.
The occupation followed the earlier Munich Agreement, which had already ceded the Sudetenland to Germany. By seizing the rest of the country, Hitler violated previous international guarantees and signaled the end of the policy of appeasement by Western powers.
