Demographic history of Poland

The Poleshuks, or Polishchuks, also known as Polesians (, , , ) are the indigenous population of Polesia (also known as Polesie and Polissia). Their native speech forms a dialect continuum between the Belarusian and Ukrainian languages and includes recently codified West Polesian, as well as many local variations and sub-dialects.

Tutejszy was a self-identification of Eastern European rural populations, who did not have a clear national identity. The term means "from here", "local" or "natives". Linguistically, the term is closely associated with speakers of the so-called prostaya mova ('simple speech'), an uncodified vernacular based on Belarusian dialects with influences from Polish, Russian, and Lithuanian.
