I know the mongols raped and pillaged across asia and europe, but wouldn't Alexander's army have done the exact same thing? Barbaric violence was common, so why view Alexander as great and Genghis evil when he accomplished more? I've heard some people say it's due to racist portrayals of asian peoples compared to western europeans.
Greetings. Not to discourage further responses, but do check these older answers while you wait :
Why is Alexander the Great remembered in history as a great general and valient leader while other conquerors in history like Ghengis Khan are demonized? by u/Iphikrates and u/lcnielsen
Hope this helps.
