After learning more about the assassination of Franz Ferdinand I wondered, what would have happened, if he never had been shot. Similar to the man in the high castle, I want to explore an alternative present, in which someone traveled back in time (or by some other means) and distracted Gavrilo Princip, so that the assassination had been planned, and the bomb had still gone of, but Franz Ferdinand would not have died.
there still would have been an assassination attempt. Could this still be linked back to Serbia the nation, or would this be enough to avoid war?
If there was no war because of this specific event, would war still have been inevitable, because the assassination was mostly a pretense?
What effects would this have on the broader world, in say 1950. Would there still be a monarchy in Germany and Austria Hungary? Would Austria Hungary survive? Who would be the technological superpowers at this time? Would we be more behind because of all the technology developed in the war?
What are the consequences for other political movements? Presumably, there would be no Nazis despite the antisemitism of the time, because there would still be the empire, and there would not be the treaty of Versailles and hyperinflation etc. What about Marxism?
