Who is the richest King in the world? Top 10 world’s richest monarchs

Ever wondered what it's like to have generational wealth taken to the absolute extreme? While we're out here celebrating our first car purchase or saving up for a house deposit, there's a whole category of people whose bank accounts would make Elon Musk do a double-take. We're talking about the world's richest kings and queens – and trust me, their level of wealth is absolutely mind-blowing.

Here's something that might surprise you: over 40 countries around the world still have kings, queens, sultans, and other monarchs running things. Now, before you start thinking these are just ceremonial positions where people wave from balconies, think again. Some of these royal figures are sitting on personal fortunes that would fund entire countries' budgets. We're talking about wealth that makes our richest celebrities and business moguls look like they're operating small corner shops.

Picture this: while most of us dream of owning one nice car, these monarchs are out here with collections of over 300 luxury vehicles. While we're excited about booking that one vacation flight, they're choosing between 38 different private jets. Their property portfolios are equally insane – thousands of buildings in major cities, stakes in the biggest companies, and wealth that's been building up for literally centuries. The numbers we're about to share will definitely make you question what rich really means.
