How Did Ancient Humans Invent Etiquette

Around 2400 BC, in the court of an Egyptian pharaoh named Djedkare Isesi, an aging vizier named Ptahhotep sat down to write something remarkable. He was old, tired, and preparing to hand his position to his son — and instead of leaving behind wealth or property, he left behind a set of written instructions on exactly how to behave. How to speak in front of a superior. When to stay silent. How to listen to a petitioner without cutting them off before they've finished. How to treat someone beneath your own social station. It's considered, by many historians, the oldest known writing anywhere in the world specifically devoted to the rules of proper conduct — meaning etiquette isn't simply old. It may be one of the very first things humans ever bothered to write down at all.
