The British monarchy practically oozes pomp, pageantry, and glamour. It also beats with a strong pulse of history, and nothing proves that more than the list of rules that members of the family must adhere to (seriously, it’s like a Walgreens receipt).

We’ve rounded up 10 of them that may come as a surprise. Scroll through to see them now, then find out which rules you have to follow should you be in the presence of royalty.
