In her book, "The Uralic language family: facts, myths, and statistics", linguist Angela Marcantonio argues against the existence of the Uralic family, claiming that the languages are no more closely related to each other than they are to various other Eurasian languages.

Up to the beginning of the 19th century, knowledge on the Uralic languages spoken in Russia had remained restricted to scanty observations by travelers. Already Finnish historian Henrik Gabriel Porthan had stressed that further progress would require dedicated field missions.

Still more extensive were the field research expeditions made in the 1840s by Matthias Castrén (1813–1852) and Antal Reguly (1819–1858), who
