By the beginning of the 17th century, some 20% of the total male population of Catalonia was made up of French immigrants.[3] In the 18th century and early 19th century, a small migration of French emigrated by official invitation of the Habsburgs to the Austro-Hungarian Empire, now the nations of Austria, Czech Republic, Hungary, Slovakia, Serbia and Romania.[4] Some of them, coming from French-speaking communes in Lorraine or being French Swiss Walsers from the Valais canton in Switzerland, maintained for some generations the French language and a specific ethnic identity, later labelled as Banat (French: Français du Banat). By 1788 there were 8 villages populated by French colonists.[5]
