or Pogórzanie

Pogórzanie (Polish Uplanders), also known as Western Pogorzans and Eastern Pogorzans, are a distinctive subethnic group of Poles that mostly live in the Central Beskidian Range of the Podkarpacie highlands. The Pogorzans inhabited the central and the southern half of the Beskids in Poland, including the Ciężkowickie, Strzyżowskie and Dynowskie Plateau as well as Doły Jasielsko Sanockie, from the White River (Biała) in the west to the San River in the east.
