More plots on war and culture

Oh this is fun. National identity.

English vs. British:

The two spikes in the 19th century are 1837 and 1859. 1837 is the coronation of Queen Victoria, I suppose. 1859 I'm not sure about.

German:

 

Here the world war spikes are obvious. Also interesting is the sustained rise from the postwar low. Quite a contrast with both British and English. 

France and America are quite similar. France has huge spikes for the two world wars, and earlier for 1813-15

America has little spikes for the world wars, and possibly a high for Vietnam (1964-1975) though I could not tell you if it would pass statistical significance. (I thought that after Vietnam there would be a postwar low as for Germany. But apparently Vietnam was a tie.)
