Bhumibol Adulyadej

Bhumibol Adulyadej (December 5, 1927 – October 13, 2016) was Thailand's ninth king, designated Rama IX, and was given the title King Bhumibol the Great in 1987 (formally awarded by King Vajiralongkorn in 2019). He was the world's longest-reigning current head of state from the death of Emperor Hirohito of Japan in 1989 until his own death in 2016, and he reigned for 70 years and 126 days, making him the second-longest reigning monarch for which specific dates are available. He was serviced by 30 prime ministers during his tenure, starting with Pridi Banomyong and ending with Prayut Chan-o-cha.

The royal household's and the Crown Property Bureau's (CPB) post-devaluation fortune is estimated to be worth between $10 and $20 billion. Forbes issued its 2008 edition of The World's Richest Royals in August 2008, and King Bhumibol was placed first, with a net worth of US$35 billion. A few days later, Thailand's Ministry of Foreign Affairs released a statement claiming that the Forbes story wrongly confused the CPB's and Bhumibol's fortune. The Thai government's complaints were noted in the 2009 Forbes list, but Forbes defended the inclusion of the CPB's holdings by claiming that the bureau is accountable for the Crown's property and interests. Due to decreases in real estate and equities, the 2009 estimate was cut to US$30 billion, and this amount was also reported in April 2014 by Business Spectator, which also verified that the CPB is the entity in charge of the Crown's wealth management.
