King Bhumibol Adulyadej is famous for being the long-time ruler of Thailand. He is the ninth king of the Chakri dynasty and may also be referred to by his dynastic title, Rama IX. His rule began in 1946.
As of 2014, King Bhumibol Adulyadej is the longest currently reigning monarch. Born in Cambridge, Mass. on Dec. 5th, 1927, Adulyadej was not originally expected to ever be considered for the throne. A series of internal struggles within the royal family led to several other candidates being passed over in favor of Adulyadej's older brother in 1945. His brother was assassinated under mysterious circumstances in 1946, and Adulyadej assumed the throne. Despite subsequent coups and political upheaval, Adulyadej has remained one of the wealthiest living rulers.
