I stumbled across this fascinating map of Europe’s languages the other day - each colour represents a different language.

Russia is by far the most linguistically diverse country in Europe. As well as Russian, I counted eight different languages within the European borders of Russia - plus there are who knows how many more distinct languages spoken in Siberia and the Far East.
Few other countries seem to have more than one or two native languages - Romania heads up the rest of the pack with, by my count, six native languages.
And also Russia seems to be one of the most widespread first languages outside of its home country. From what I can tell, it has spread to seven different European countries - Kazakhstan, Ukraine, Belarus, Latvia, Estonia, Romania and Finland.
