Around 5000 BC the Indoeuropeans all spoke one single language.
By 1000 AD there were dozens of languages in Europe and who knows how many dilects.
What if there would have been only like 6 languages in Europe?
One Germanic spoken in central Europe, Scandinavia and Britain.
One Romanic spoken in Spain, France, Portugal and Italy.
One Slavic spoken from Kiev to Bohemia
A Finno-Baltic one and Hngarian and Greek.
Would Europe have been more united- at least the regions with the same language??
