The  Severians (Северяне, Severyane; also called Siverians, or Severyans) were an East Slavic tribe that lived in the middle Dnieper River region during the early medieval period. They are mentioned in historical sources like the Primary Chronicle (1113) and Byzantine records.

Key Facts About the Severyane:

• They inhabited areas east of the Dnieper River, including parts of modern Ukraine, Belarus, and Russia.
• Some theories suggest their name comes from the Slavic word "sěver" (north), though they were not the northernmost Slavic tribe.
• Others propose an Iranic origin, possibly linked to the Sarmatian Seuer tribe, where "seu" meant "black".
• They were subjugated by the Khazars before becoming part of Kievan Rus in the late 9th century.
• Some Severians migrated to Bulgaria, where they were absorbed into the local Slavic population.

Their legacy lives on in the historical region of Severia, which was named after them.
