Irish Travellers (an lucht siúil, meaning "the walking people"), also known as Pavees or Mincéirs (Shelta: Mincéirí), are a traditionally peripatetic indigenous ethno-cultural group originating in Ireland. They are predominantly English-speaking, though many also speak Shelta, a language of mixed English and Irish origin. The majority of Irish Travellers are Roman Catholic, the predominant religion in the Republic of Ireland. They are one of several groups identified as "Travellers" in the UK and Ireland. They are often incorrectly referred to as "Gypsies", but Irish Travellers are not genetically related to the Romani, who are of Indo-Aryan origin. Genetic analysis has shown Travellers to be of Irish extraction, and that they likely diverged from the settled Irish population in the 1600s, probably during the time of the Cromwellian conquest of Ireland. Centuries of cultural isolation have led Travellers to become genetically distinct from the settled Irish. Traveller rights groups long advocated for ethnic status from the Irish government, succeeding in 2017. Irish Traveller communities can be found in Ireland, the United Kingdom, the United States and Canada. As of 2016, there are 32,302 Travellers within Ireland. They represent 0.7% of the total population of the Republic of Ireland. There are different estimates about the size of the total population of people with Traveller ancestry, because many people of Traveller descent do not declare themselves Travellers. The United Kingdom alone is believed to be home to up to 300,000 Traveller people. Travellers refer to themselves in Gammon as minkiers or in Irish as an lucht siúil ("the walking people"). There are numerous theories and oral histories surrounding the origins of Irish Travellers as a distinct group. Research has been complicated by the fact that the group appears to have no written records of its own, with oral tradition through storytelling being the primary method through which the Traveller community disseminates its own history and culture.
