What are the limits of Europe? Is it a geographical unit, a continent, a geopolitical space, or a cultural unit? Is it possible to conceive of a united Europe from the Atlantic to the Urals? More than 40 million inhabitants live in Siberia, of which 95% are ethnically and culturally equal to the inhabitants of St. Petersburg or Moscow. Are the Siberian Russians and Europeans who live west of the Urals Asian? Is Turkey a European country? Is it Georgia, which is part of the Council of Europe and has applied to join NATO? Europe is a historically constructed cultural concept and its limits have been changing over time.
