German Dienstpost cover with Scott Nos. 180 and N1 cancelled in Luxemburg on
1 October 1940, the first day of validity for the German issued stamps of occupied Luxembourg, now known as Luxemburg. The stamps of Luxembourg remained valid for postage until 2 October 1940. Officially permitted mixed-postages of stamps from Luxembourg and Germany, on one cover, were possible on these two days only and are extremely scarce.
The people of Luxembourg are of French and German ethnicity, a majority of whom speak Letzeburgesch (Luxeinburgian), a Germanic tongue. French and German are used for the most part for administrative purposes. The population is predominantly Roman Catholic, with some Protestants (mostly Lutherans) and a small Jewish minority. The bulk of the population is concentrated in Luxemburg city and in the smaller cities of the southwest, which has been the grand duchy’s industrial heartland since the late 19"' century.
