Luxembourgers

Luxembourgers ( , , ) are a Germanic ethnic group and nation 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.
Luxembourgers were, much like Austrians, historically considered to be a regional subgroup 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".
Location.
Most ethnic Luxembourgers live in the Grand Duchy of Luxembourg, a small country in Europe between Germany, France, and Belgium, and are of Celtic/Gallo-Roman and Germanic (Frankish) origin. Most speak Luxembourgish, as their native language, in addition to French and German. Despite the rather small number of Luxembourgers, there is a relatively large diaspora, in Europe and elsewhere. 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.
There are also significant populations in the Americas, with the largest contingent being in the United States. However, many people of Luxembourgish descent also live in Canada and Brazil, to which large waves of Luxembourgers emigrated in the nineteenth century, as did Germans at the same time. Others migrated to Hungary along with Germans during the first phase of German eastward settlement in the 12th century. Transylvanian Saxons and Banat Swabians are the descendants of these settlers.
