The Vlaxika or Olaši represent the Vlax group within Bohemia and Slovakia. Generally they have preserved a lot of older Romani traditions and until recently have been itinerant. The prototype profession is trading and peddling, in the past also with horses. The gender roles are clearly defined and strictly separated. The internal rules of the community are regulated by the society as a whole and by a self-governmental body, kris. Family ceremonies are very formalised and solemn.
