What’s a historical fact that would shock most people to find out?

Just how much food Henry the 8th would eat each day. What the Apaches like to do to their enemies or that Japanese expirement unit during WW2, the one that did tests on people. How badly they messed up any form Indian relief during the many famines in India during British rule. British and Indian local rule alike. The plauge of Justinian. The Taiping rebellion, that was a laugh for all involved. How many Christian saints there are and all the stupid stories behind how they became saints. What a jerk Charley Chaplin was.
