The Baltic Finnic or Balto-Finnic peoples, also referred to as the Baltic Sea Finns, Baltic Finns, sometimes Western Finnic and often simply as the Finnic peoples, are the peoples inhabiting the Baltic Sea region in Northern and Eastern Europe who speak Finnic languages. They include the Finns, Estonians (including Võros and Setos), Karelians (including Ludes and Livvi), Veps, Izhorians, Votes, and Livonians. In some cases the Kvens, Ingrians, Tornedalians and speakers of Meänkieli are considered separate from the Finns.
The bulk of the Finnic peoples (more than 98%) are ethnic Finns and Estonians, who reside in the only two independent Finnic nation states—Finland and Estonia.
Finnic peoples are also significant minority groups in neighbouring countries of Sweden, Norway and especially Russia.
According to the "Migration Theory" that was based primarily on comparative linguistics, the proto-Finns migrated from an ancient homeland somewhere in north-western Siberia or western Russia to the shores of the Baltic Sea around 1000 BC, at which time Finns and Estonians separated. The Migration Theory has been called into question since 1980 based on genealogy, craniometry and archaeology. Recently, a modified form of the Migration Theory has gained new support among the younger generation of linguists, who consider that archaeology, genes and craniometric data cannot supply evidence of prehistoric languages.
During the last 30 years, scientific research in physical anthropology, craniometric analyses, and mitochondrial and Y-chromosomal DNA frequencies have reduced the likelihood of the Migration Theory—a major westward migration as recently as 3,000 years ago. The Settlement Continuity Theory asserts that at least the genetic ancestors of the Finnic peoples were among the earliest indigenous peoples of Europe.
The origin of the people who lived around the Baltic Sea area during the Mesolithic Era continues to be debated by scientists.
