The group originates from the north west Masovia, located within borders of the Masovian Voivodeship, Poland. Historically, that area was part of the region known as the Duchy of Łowicz, a private estate of the Roman Catholic Archdiocese of Gniezno. The group had enjoyed more freedoms than the neighboring people, and as such, which contributed to them developing a separate identity. They also were freed from the Serfdom much earlier than other groups in the region, further building their cultural identity separate from the other groups.[2][3]
