Groupings by compass directions are the hardest to define in Europe, since there are a few calculations of the midpoint of Europe (among other issues), and the pure geographical criteria of "east" and "west" are often confused with the political meaning these words acquired during the Cold War Era.
Central Europe
Eastern Europe
Northern Europe
Southern Europe
Western Europe
There are also physical geographic regions, such as the central up-lands and the European plain.
The geographic scheme in use by the United Nations created for internal use by the statistics division includes all of the above divisions, save Central Europe.
Europe can be divided along many differing historical lines, normally corresponding to those parts that were inside or outside a particular cultural phenomenon, empire or political division. The areas varied at different times, and so it is arguable as to which were part of some common historical entity (e.g., were Germany or Britain part of Roman Europe as they were only partly and relatively briefly part of the Empire—or were the countries of the former communist Yugoslavia part of the Eastern Bloc, since it was not in the Warsaw Pact).
Roman and Non-Roman Europe: those parts that were inside or outside the Roman Empire.
Greek Europe and Latin Europe: those parts that fell into the eastern (Byzantine) and western Roman Empires.
Monotheistic Christian and polytheistic Pagan Europe: those lands that did and did not observe Christianity in the Middle Ages.
Catholic and Orthodox Europe: those parts on either side of the Great Schism.
After Reformation: countries of Western Christianity (Catholic and Protestant Churches) and Eastern Christianity (Eastern Orthodox Church, Assyrian Church of the East, Oriental Orthodox churches and the Eastern Catholic Churches)
Protestant and Catholic Europe: those parts that, in the main, left the Catholic Church during the Reformation contrasted with those that did not.
Communist Europe (Eastern Bloc), Capitalist Europe (Western Bloc) - those parts on either side of the Iron Curtain and third world countries (neutral and non-aligned during the Cold War).
