Question

how did the British royalty become “ royal”. What started this 1000 years ago?

In: 1643

Answer 1

If you invade a place, you get to make yourself ruler of it. The current royal family is descended from people that invaded England and proclaimed themselves rulers of it (namely William the Conqueror in 1066, but it’s a complicated ancestry compared to, say, Denmark, where it’s a straight line).
