If you can see the outcome of just one historical event going differently up to the present-day, which one would you choose? As for me, it would be Gavrilo Princip failing to shoot Franz Ferdinand and his wife Sophie. I'd like to see if World War I would have ever occurred later on in such a scenario as well as how such a world would have looked like right now.
If I could choose a second event as well, I would choose Tsar Peter III of Russia not making peace with Prussia in 1762 and instead fighting the Seven Years' War up to the very end, destroying Prussia as a military power in the process and seizing East Prussia from Frederick the Great and giving it to the PLC in exchange for Courland while Austria gets Silesia back. I'd certainly like to see how that world would have turned out by the present-day.
