Luxembourgish language
The Government in Exile first fled to Paris, then after the Fall of France, to Lisbon and then the United Kingdom. While the Government established itself in Wilton Crescent in the Belgravia area of London, the Grand Duchess and her family moved to Francophone Montreal in Canada. The government in exile was vocal in stressing the Luxembourg cause in newspapers in allied countries and succeeded in obtaining 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.
