What is Alternative History? Simply put, alternate history is the exercise of looking at the past and asking “what if”? What if some major historical event had gone differently? How might the world have been changed immediately, and in the long term? Popular “what if” questions include “what if the Nazis had won WW2?” and “what if the South had won the US Civil War?” Wiki: https://www.alternatehistory.com/wiki/doku.php?id=alternate_history%3Aalternate_history_faq
