47. Maha Vajiralongkorn – $30 billion
Maha Vajiralongkorn is the richest monarch.
Vajiralongkorn succeeded to the throne of Thailand as the tenth king of the Chakri Dynasty following the death of his father in 2016. His patience was put to quite a test. Named crown prince at the tender age of 20, he had to wait until turning 64 to see his dream come true.
Despite Thailand having a strict law forbidding any form of criticism directed at the royal family, some couldn’t keep their mouths shut. Vajiralongkorn often made bizarre public appearances wearing a crop top and revealing the vast collection of tattoos on his body.
