Bhumibol Adulyadej (Thai: ภูมิพลอดุลยเดช; RTGS: Phumiphon Adunyadet; pronounced [pʰuːmípʰōn ʔàdūnjādèːt] ; see full title below; born 5 December 1927) is the reigning King of Thailand. He is known as Rama IX. Having reigned since 9 June 1946, he is the world's longest-serving current head of state and the longest-reigning monarch in Thai history, having served for 700168000000000000068 years, 700151000000000000051 days.King Bhumibol is respected and revered by many Thais. The King is legally considered "inviolable", and lèse majesté, that is, offence against the dignity of the monarch may be punished. In 1957, the overthrow of the government was justified with allegations of lèse majesté. Although Bhumibol invited public criticism in a 2005 speech, politicians and individuals are still being arrested, though most are pardoned.Bhumibol is credited with a social-economic theory of self-sufficiency. Forbes estimated Bhumibol's personal fortune, including property and investments—managed by the Crown Property Bureau (CPB), a unique body that is neither private nor government-owned—to be US$30 billion in 2010, and he was the leader of the magazine's list of "The World's Richest Royals" from 2008 to 2013. This estimation includes land ownership that the royal family says it does not own and royal courtiers insist that the CPB's assets are not the personal property of the king and belong to the crown.The Crown Property Bureau spends money on public welfare such as youth development, however it does not pay taxes and its finances are reported only to Bhumibol. Bhumibol himself has made donations to numerous development projects in Thailand, in areas including agriculture, environment, public health, occupational promotion, water resources, communications and public welfare. Commemorations of Bhumibol's contributions to Thailand are ubiquitous in the Thai media.
