'What is a German's fatherland?', asked Ernst Moritz Arndt at the
beginning of the nineteenth century. This has arguably been the central
question of modern German history. Germans did not have a united
fatherland until 1871, and, thereafter, major political events in 1918,
1933, 1945, 1968 and 1989 ensured that the answers to Arndt's question
proliferated and diverged with breath-taking speed.
