Uralic languages impetus from the fact that these languages, unlike most of the other languages spoken in Europe, are not part of what is now known as the Indo-European family. In 1717, Swedish professor Olof Rudbeck proposed about 100 etymologies connecting Finnish and Hungarian, of which about 40 are still considered valid. Several early reports comparing Finnish or Hungarian with Mordvin, Mari or Khanty were additionally collected by Leibniz and edited by his assistant Johann Georg von Eckhart. In 1730, Philip Johan von Strahlenberg published his book ("The North and East Parts of Europe and Asia"), surveying the geography, peoples and languages
Indo-Uralic languages borrowed between them, most often from Indo-European languages into Uralic ones. An example of a Uralic word that cannot be original is Finno-Ugric *"śata" "hundred". The Proto-Indo-European form of this word was *"ḱm̥tóm" (compare Latin "centum"), which became *"ćatám" in early Indo-Iranian (reanalyzed as the neuter nominative–accusative singular of an "a" stem > Sanskrit "śatá-", Avestan "sata-"). This is evidence that the word was borrowed into Finno-Ugric from Indo-Iranian or Indo-Aryan. This borrowing may have occurred in the region north of the Pontic-Caspian steppes around 2100–1800 BC, the approximate floruit of Indo-Iranian (Anthony 2007:371–411). It provides linguistic evidence for the
