Luxembourgers (ˈlʌksəmbɜːrɡərz ; Lëtzebuerger ˈlətsəbuəjɐ) are an ethnic group native to their nation state of Luxembourg, where they make up around half of the population. They share the culture of Luxembourg and speak Luxembourgish, a West Germanic language.
Luxembourgers were, much like Austrians, historically considered to be a regional sub-group of ethnic Germans and viewed themselves as such until the collapse of the German Confederation. Luxembourg became independent, while remaining in personal union with the Netherlands, after the signing of the Treaty of London in 1839. The personal union proved short-lived as it was bilaterally and amicably dissolved in 1890.
Legally, all citizens of the Grand Duchy of Luxembourg are considered to be Luxembourgers per Luxembourgish law, although a distinct Germanic ethnolinguistic identification is vocally espoused and promoted. The corresponding adjective is "Luxembourgish".
Most ethnic Luxembourgers live in the Grand Duchy of Luxembourg (Lëtzebuerg), a small landlocked country in Western Europe, situated between Germany, France, and Belgium, and are of Celtic/Gallo-Roman and Germanic (Frankish) origin. Luxembourgish is the only native language of Luxembourgers (as taught by parents), although nearly all of them learn French and German in school and are able to communicate in these two languages as well from an early age on. Despite the rather small number of Luxembourgers, there is a relatively large diaspora of their people, both in Europe and elsewhere, most notably overseas in North America. Particularly, there are populations in the surrounding countries of Belgium, France, and Germany. For the most part, this is due to historic reasons, especially the three Partitions of Luxembourg, which led to former territories of Luxembourg being incorporated into each of the three surrounding countries.
As previously mentioned, there are also significant populations of Luxembourgers in the Americas, with the largest contingent being in the United States.
