“Between 1714 and 1830, every king of England was named George. They were all members of the House of Hanover, which is in Germany. It rather embarrassed the English to have to import their royal family from Germany, but they didn’t have much choice. They’d more or less run out of Stewarts. (Well, no entirely, but that’s another story.) Anyway, the first four Hanoverians were all called George. To make them easier to tell apart, they were numbered, with typical Germanic efficiency, George I, George II, George III, and George IV.”
