I'll start with my own. I am not 100% sure this is true, but one of my European history teacher once told us that Napoléon Bonaparte was in fact the average height of a french man in his time, and that the idea of him being small was a form of ''propaganda'' by the British to hinder his prestige.

I'm sorry, but we do not allow questions like these in our sub. The reason for this is the fact that this falls under our 'trivia question ban'. Since your question is so unspecific (and broad), it would unfortunately invite bad answers.
