Both ancient and modern.
The last time every European country was occupied
Very subjective topic. For example Turkey was conquered by the Ottomans from the Byzantine Empire, which was previously the Roman Empire and the Romans took it from the Greeks, who took it from the Persians and on and on... The UK was taken by the Normans in 1066. Prior to that the Danes and Saxons fought over it after taking it from the Celtic Britons, who almost certain took it from someone else that no one remembers. It's all in your perspective.
Europe Suicide rate. This map intrigues me because I cannot figure the demographics that determine whether or why a particular country has a low or high rate. Clearly there are a number of different influences factoring into each country's rate. I would imagine the following factors influence the numbers: Economic status, Alcoholism, Climate, Religion and Culture. But even considering all of these, I am still left puzzling over some of the results. Would be an interesting study.
