Vajiralongkorn, born on 28 July 1952 and also known by his regnal name Rama X, is the tenth monarch of the Chakri dynasty and the reigning King of Thailand. He is the only son of King Bhumibol Adulyadej and Queen Sirikit. He was educated in Thailand, the United Kingdom and Australia, and graduated from the Royal Military College, Duntroon.

He served as an officer in the Royal Thai Army, trained with British, Australian and United States forces, and qualified as a military fast-jet pilot and a commercial airline pilot. He also saw combat against the Communist Party of Thailand in the 1970s. He was designated crown prince in 1972.

After his father died on 13 October 2016 he succeeded to the throne; following a brief delay he was formally proclaimed on 1 December 2016, and his coronation took place in May 2019. Since taking the throne he has requested changes to the draft 2017 constitution concerning royal prerogatives, taken direct ownership of the assets managed by the Crown Property Bureau, and brought key military and security units under direct royal command, centralising royal power.
