King Maha Vajiralongkorn

Thailand's King Maha Vajiralongkorn is the world's richest monarch, with an estimated net worth of up to $59 billion. The king's fortune is enormous, but people have recently been more interested in his personal life than his wallet.

During the coronavirus outbreak, Maha Vajiralongkorn reportedly booked out every single room in a hotel in Germany to self-isolate with his harem of 20 women and his staff. More recently, while visiting his mother in the hospital, he instructed residents to cover their curtains and not stare out of them.

After his father died in 2016, the 67-year-old monarch ascended to the throne. The Crown Property Bureau is in charge of his fortune. His family owns around 16,210 acres of property in Thailand, as well as 40,000 rental contracts throughout the country, including 17,000 in Bangkok. The King also has a substantial stake in the Siam Cement Group and the Siam Commercial Bank. As if that wasn't enough, the Thai monarch also owns the Golden Jubilee Diamond, which is the world's biggest cut and faceted diamond.
