When Luxembourg was invaded and annexed by Nazi Germany in 1940, a national consciousness started to emerge. From 1941 onwards, the first resistance groups formed in secret, operating underground and in defiance of the German occupation. Their covert activities included aiding political refugees and those evading conscription into the German forces, as well as disseminating patriotic leaflets to bolster the Luxembourgish population's spirits.

Volksdeutsche Bewegung was a Nazi movement in Luxembourg that flourished under the German-occupied Luxembourg during World War II.
