Volhynians (Polish: Wołynianie, Ukrainian: Волиняни, Volyniany) were a north-western proto-Ukrainian tribe. They are mentioned in the Primary Chronicle. Some historians believe that the Volhynians and the Buzhans are descendants of the Dulebes. A few historians claim the name comes from Celtic tribes known as Bolihii before the arrival of Slavic tribes in the 6th century. The Volyhnians lived in the region of Volhynia that covered present-day sections of eastern Poland, western Ukraine and southern Belarus.
Note the term Volhynian was used to name the Poles or Volen, Polen or Polan, but the Poles named them Wolyn or Wolhynske in their language. The name was also used for local groups of non-Slavic peoples that lived in the historic region: Magyars as in Vaelan Hungarians, Vlachs or Volaches as in Volhynian Romanians, and Volhynian Germans as in Wolenes or Wellanes. In Yiddish, Ashkenazi Jews residing in the area were referred to as Voliners (וואָלינערס).
