Alternative history is an interesting concept to think about. What if the Nazis had won WW2? Why if Duke Ferdinand hadnt been assassinated? What about Lincoln? My favorite one that I read about was a hypothetical scenario where the Romans accidentally discovered steam power 1500 years ahead of time. In present day, based on the rate of technological progression, they would control the entire Earth and planets within our solar system. Focus: What change in a historical event would have the biggest impact on how history has played out? What do you think would be different in the world today because of it?
