King Harald v of Norway
So, what was King Harald V like as a young whippersnapper? Well, he was educated in the ways of warfare and politics at the Norwegian Military Academy, which is like the Hogwarts of Norway, but instead of magic wands, they use skis and hiking boots. He also studied economics at the University of Oslo, because even royals need to know how to balance a budget.
But it wasn't all books and lectures for King Harald V. He was also a bit of a rebel, and was known to sneak out of the palace to go snowboarding (okay, maybe not snowboarding, but he did like to get out and have some fun). And fun fact: he's a descendant of Viking kings, which means he's got some serious Norse cred.
