German Revolution of 1918: Kaiser Wilhelm II, ruler of Germany, abdicates, leading to the formation of the Weimar Republic in the wake of World War I. Popular uprisings during the first week of November have already led to relatively bloodless seizures of power by workers' and soldiers' councils in cities all around Germany.
Traditionalist and conservative elements of German society will never entirely accept the Republic or democracy, a fact which Adolf Hitler will later use to great effect. The grandmaster of the Thule Society of Munich, addressing his organization, is reported to say:
"Yesterday we experienced the collapse of everything which was familiar, dear and valuable to us. In the place of our princes of Germanic blood rules our deadly enemy: Judah.
What will come of this chaos, we do not know yet. But we can guess. A time will come of struggle, the most bitter need, a time of danger."
This is exactly the attitude which will drive the popularity of the Nazi Party two decades from now, and it's an attitude that will be common among conservatives and nationalists, even those not especially fond of the Nazis.
