The Uralic languages are a family of languages spoken predominantly in Europe and North Asia. The three with the most native speakers are Hungarian, Finnish, and Estonian. Other members include Erzya, Moksha, Mari, Udmurt, and Komi in European Russia, as well as Sami languages of northern Fennoscandia, Mansi and Khanty in Western Siberia, and the Samoyedic languages.
The exact homeland of the Uralic languages is disputed. The name derives from a hypothesized original homeland near the Ural Mountains, first proposed by Julius Klaproth in 1823. Competing proposals place the homeland between the Volga and Kama Rivers, in the Ob-Yenisei drainage basin of Central Siberia, or, according to a 2025 genetic study by Zeng and colleagues, connected to ancient populations in Northeastern Siberia around 4,500 years ago.
The affinity of Hungarian and Finnish was first proposed in the late 17th century by three scholars: the German scholar who commissioned an unpublished comparative study through Cosimo III of Tuscany, the Swedish scholar Georg Stiernhielm, and the Swedish courtier Bengt Skytte. In 1717, Olof Rudbeck proposed about 100 etymologies connecting Finnish and Hungarian, of which roughly 40 are still considered valid.
A computational phylogenetic study by Honkola and colleagues in 2013 estimated the divergence of the entire Uralic family at approximately 5,300 years before the present. Within the family, Finno-Ugric diverged around 3,900 years ago, and the Ugric branch split roughly 3,300 years ago.
Uralic languages are agglutinative, building words by stringing morphemes together. They typically have large numbers of grammatical cases, ranging from 6 in Northern Sami to 27 in some Komi dialects, with Finnish having 15 and Hungarian 18. They also lack grammatical gender, using a single pronoun for both he and she, and use postpositions rather than prepositions.
The Finno-Ugrian Society was founded in Helsinki in 1883 on the proposal of Otto Donner. It hired scholars to survey the less-known Uralic languages during the late 19th and early 20th century, and its expeditions collected vast amounts of data that provided over a century's worth of editing work for later generations of Finnish researchers.
