The Protectorate of Bohemia and Moravia was a partially-annexed territory of Nazi Germany that was established on 16 March 1939 after the German occupation of the Czech lands. The protectorate's population was mostly ethnic Czechs.
After the Munich Agreement of September 1938, the Third Reich had annexed the German-majority Sudetenland to Germany from Czechoslovakia in October 1938. Following the establishment of the independent Slovak Republic on 14 March 1939, and the German occupation of the Czech rump state the next day, German leader Adolf Hitler established the protectorate on 16 March 1939, issuing a proclamation from Prague Castle. The creation of the protectorate violated the Munich Agreement.
The protectorate remained nominally autonomous and had a dual system of government, with German law applying to ethnic Germans while other residents had the legal status of Protectorate subjects and were governed by a puppet Czech administration. During World War II (1939–1945), the well-trained Czech workforce and developed industry were forced to make a major contribution to the German war economy. Since the Protectorate was just out of the reach of Allied bombers based in Britain, the Czech economy was able to work almost undisturbed until the end of the war. The Protectorate administration became deeply involved in the Holocaust in Bohemia and Moravia.
The state's existence came to an end with the surrender of Germany to the Allies in May 1945. After the war, some Protectorate officials were charged with collaborationism, but according to the prevailing belief in Czech society, the Protectorate was not entirely rejected as a collaborationist entity.
