When it comes to the easiest ways to get rich, being born into a royal family must come pretty close to the top.
These fabulously wealthy individuals have huge inherited riches, often thanks to the country they rule having deposits of oil and other valuable natural resources.
Then there’s the ownership of palaces, castles, jewels and art collections.
