Geographica: Europe
What am I supposed to do about the United Kingdom? Do I count England, Scotland, Wales, and Northern Ireland as "countries"? None is itself a sovereign state, but then again there is no doubt I'll count Monaco, which isn't exactly entirely sovereign itself. Bugger it. Also, I am not counting Russia or Turkey. Both have toeholds in Europe, but the majority of their lands are in the vastness of Asia.

Cyprus is another tricky one. The island is closer to the Asia Minor part of Turkey, clearly establish above as being part of Asia rather than Europe, then Greece. But, the majority population is Greek and Cyprus has been admitted into the European Union, to which Turkey is an candidate, but, let's be honest, Turkey will only ever accede to the EU over France's dead body.

Tomorrow: Asia.
