The Yenish (German: Jenische; French: Yéniche) are an itinerant group in Western Europe who live mostly in Germany, Austria, Switzerland, Luxembourg, Belgium, and parts of France, roughly centred on the Rhineland. A number of theories for the group's origins have been proposed, including that the Yenish descended from members of the marginalized and vagrant poor classes of society of the early modern period, before emerging as a distinct group by the early 19th century. Most of the Yenish became sedentary in the course of the mid-19th to 20th centuries. Name The Yenish people as a distinct group, as opposed to the generic class of vagrants of the early modern period, emerged towards the end of the 18th century. The adjective jenisch is first recorded in the early 18th century in the sense of "cant, argot". A self-designation Jauner is recorded in 1793. Jenisch remains strictly an adjective that refers to the language, not the people, until the first half of the 19th century. Jean Paul (1801) glosses jänische Sprache ("Yenish language") with so nennt man in Schwaben die aus fast allen Sprachen zusammengeschleppte Spitzbubensprache ("this is the term used in Swabia for an argot used by young rogues which has been conflated from all sorts of languages"). An anonymous author in 1810 argues that Jauner is a deprecating term, equivalent to "cardsharp", and that the proper designation for the people should be jenische Gasche. Germany Many Yenish people in Germany became sedentary in the second half of the 19th century. The Kingdom of Prussia in 1842 introduced a law forcing municipalities to provide social welfare to permanent residents without citizenship. As a consequence, there were attempts to prevent Yenish people from taking permanent residence. Recently established settlements of Yenish, Sinti, and Roma, dubbed "gypsy colonies" (Zigeunerkolonien), were discouraged and attempts were made to incite the settlers to move away, in the form of various forms of harassment, and in some cases physical attacks. By the late 19th century, many recently sedentary Yenish were nevertheless integrated into local populations, gradually moving away from their tradition of endogamy thus being absorbed into the general German population. Those Yenish who did not become sedentary by the late 19th century took to living in trailers. The persecution of Romani people under Nazi Germany beginning in 1933 was directed not exclusively against the Romani people but also targeted "vagrants who travel around after the manner
