Before the war, Luxembourg had pursued a policy of neutrality and only became an Allied member after being invaded by Germany on 10 May 1940. The government in exile fled, winding up in England. It made Luxembourgish language broadcasts to the occupied country on BBC radio. In 1944, the government in exile signed a treaty with the Belgian and Dutch governments, creating the Benelux Economic Union and also signed into the Bretton Woods system.
