Map of known Paleo-European languages, including substrate languages.
The Paleo-European languages are the mostly unknown languages that were spoken in Europe prior to the spread of the Indo-European and Uralic families caused by the Bronze Age invasion from the Eurasian steppe of pastoralists whose descendant languages dominate the continent today. Today, the vast majority of European populations speak Indo-European languages, but until the Bronze Age, it was the opposite, with Paleo-European languages of non-Indo-European affiliation dominating the linguistic landscape of Europe.
