Berziti
The Berziti ( Bulgarian, Macedonian, , ) were a South Slavic tribe that settled in Byzantine Macedonia in the 7th century AD with the Slavic invasion of the Balkans. The Berziti settled in the vicinity of Lychnidos ( Ohrid). One part of the same tribe settled in Brest, Belarus, while another, also known as Brsjaci, moved south into the Balkans.
