What’s in a name? Well, when you’re the future King of England, kind of a lot as it turns out! According to royal historian Robert Lacey, writing in People, when William eventually becomes king he’ll be known as King William IV, which Princess Diana suggested as a nod to a different famed English king. But Prince Charles originally proposed a very different name for his firstborn.
Lacey says that though Diana got her way when William was born in June 1982, Prince Charles had suggested calling their son Arthur—after the storied king and knight of the Round Table in British legend. However, "Diana, Princess of Wales proposed a more robust name — William, as in 'William the Conqueror,' victor of the famed Battle of Hastings in 1066,” Lacey said. Arthur would have been a very different vibe for William, though we must admit we like the sound of King Arthur II too.

But Charles’s suggestion wasn’t totally vetoed, either. The Duke of Cambridge’s full name is Prince William Arthur Philip Louis. Diana’s pick of William got the lead, Charles’s selection of Arthur came in second, a tribute to William’s grandfather Prince Philip is third, and Louis—a family name—rounds out the fourth place.
When you’re a royal you’re supposed to have a lot of names apparently, and it’s notable that Prince William and Kate Middleton gave their second-born son the name Louis, too—and his middle name is even Arthur. Those are some big names to live up to!

But Lacey writes that Diana knew even early on that William would be up to the task:
It’s hard to imagine Prince William as anything else, so it’s probably for the best that Diana got her way on the name selection.
