Baltic

Despite the three nations' similarities in culture and history, their languages belong to two distinct language families. The Latvian and Lithuanian languages make up the group of Baltic languages which belongs to the Indo-European language family. The Estonian language, on the other hand, is a non-Indo-European language and instead belongs to the Baltic-Finnic subgroup of the Finno-Ugric languages, sharing close cultural and historical ties with the Finnish language and culture.

The peoples of the Baltic countries also belong to different Christian denominations. Believers in Latvia and Estonia are mostly Lutheran (except for Eastern part of Latvia, which is Catholic). Lithuania is principally Catholic.
