Rama IX; Bhumibol Adulyadej ; 5 December 1927 – 13 October 2016), conferred with the title King Bhumibol the Great in 1987 (officially conferred by King Vajiralongkorn in 2019),was the ninth monarch of Thailand from the Chakri dynasty, titled Rama IX. Reigning since 9 June 1946, 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 is both the second-longest reigning monarch of all time and the longest-reigning monarch to have reigned only as an adult, reigning for 70 years and 126 days. During his reign, he was served by a total of 30 prime ministers beginning with Pridi Banomyong and ending with Prayut Chan-o-cha.
After a period of deteriorating health which left him hospitalized on several occasions, Bhumibol died on 13 October 2016 in Siriraj Hospital. He was highly revered by the people in Thailand – some saw him as close to divine. Notable political activists and Thai citizens who criticized the king or the institution of monarchy were often forced into exile or to suffer frequent imprisonments. Yet many cases were dropped before being proceeded or were eventually given royal pardon. His cremation was held on 26 October 2017 at the royal crematorium at Sanam Luang. His son, Maha Vajiralongkorn, succeeded him as King.
