Hypothetically, if governments wordwide just suddenly became authoritarian and deleted all records of history, you and some survivors escape to a remote area outside of government control, they all can’t remember much from history (either didn’t pay attwntion in class, or suffers memory loss from the governemtn attacks) and so you are designated as this community’s official historian. How much can you remember? What’s gonna be the official narrative of your little rebel community?
There were Romans (basically Greek cosplayers), some dude with elephants who may or may not have been a cannibal. Then some dude got nailed to some lumber for trying to tell people to chill and love eachother. A few thousand years of fighting about that. Columbo sailed to India but found Aztecs instead. The cubs finally won… And that about brings us up to date.
