The Slavic peoples used to worship pagan gods like Perun, Svarog and Veles. In this video we look at a group of Polish pagans called GROMADA BIAŁOŻAR during their May day rite. I also discuss the genetic origins of the Slavs, the Slavic expansions into the Balkans in the migration era, the conversion of slavs to Christianity and the linguistic origin of Proto-Slavic language.
