Vlax Romani people
Wallachian Roma or Vlax Roma is the generic term for various Romani groups in Southeastern Europe who speak one of the Vlax Romani dialects. Many migrated from present-day Romania to the United States in the 18th and 19th centuries to escape slavery. The Vlax Roma claim to retain Romani culture, language, and social structure despite discrimination they have faced.
In Hungary, Slovakia, and the Czech Republic, they migrated from Romania as part of the Kalderash migration wave and are subdivided into the Lovara and other groups. They are far smaller than the Hungarian Roma, who mainly speak Hungarian and integrated into Hungarian society. In Serbia, they migrated from Romania.
