In a parallel universe known as Germania LXVIII, Adolf Hitler was an International Socialist rather than a Nazi and the author of Mein Kapital. He came to power after Spartacist uprisings in 1919 and aimed to lead an international workers' revolution. To this end, Germany became allies with Russia.
After the formation of the Greater German Reich, forces from Germania I deposed the communist Hitler and put a National Socialist Hitler in his place. The native Hitler was left to roam the streets of Dresden, often being beaten up by civilians. He was eventually killed by Marcus Americanius Scriptor. (PROSE: Warlords of Utopia)
