Pripyat Marshland is often labeled homeland of original Slavs in literature.  People living the region are known as Poleshuks in Belarus. Poleshuks of Belarus wanted to gain independence in the 90s. Authorities of Belarus and the Belarusians said Poleshuks are Belarusians! That was the end of the story.

Belarusians (Poleshuks and maybe the original Slavs) of south-western Belaurs.
