We don’t know-how familiar you will be with cultural communities in Eastern Europe and the Balkans. By the video game reveals I have come across Stateside (which are far more than individuals should see), no too familiar. Essentially, Slavs are the biggest ‘tribe’.
Slavs become an Indo-European ethno-linguistic people, whom speak different Slavic languages on the Balto-Slavic language party.
That will be from Wikipedia. They initially appeared in created background across 6th century. They most likely originated from somewhere in Eastern Europe/Western Asia.
We just learned about all of them whenever Germanic tribes started migrating. Slavs decided at those deserted countries fleeing the Huns as well as their partners.
