King of Thailand in the context of "Prime Minister of Thailand"

Vajiralongkorn (born 28 July 1952), also known by his regnal name Rama X, is King of Thailand. He is the tenth monarch of the Chakri dynasty, the reigning dynasty of Thailand since 1782.

The only son of King Bhumibol Adulyadej (Rama IX) and Queen Sirikit, he was made crown prince by his father in 1972, at the age of 20. After his father's death on 13 October 2016, he requested that his formal accession ceremony be delayed to allow for time to mourn his father. On 1 December 2016, he formally accepted the throne, becoming the tenth Thai monarch of the Chakri dynasty and, at the age of 64, the oldest to ascend to the throne. The government retroactively declared his reign to have begun at his father's death on 13 October 2016. His coronation took place from 4 to 6 May 2019.

Bhumibol Adulyadej (5 December 1927 – 13 October 2016), titled Rama IX, was King of Thailand from 9 June 1946 until his death in 2016. His reign of 70 years and 126 days is the longest of any Thai monarch, the longest on record of any independent Asian sovereign, and the third-longest of any sovereign state.

Born in the United States, Bhumibol spent his early life in Switzerland, growing up in the aftermath of the 1932 Siamese revolution which toppled Thailand's centuries-old absolute monarchy, ruled at the time by his uncle, King Prajadhipok (Rama VII). He ascended to the throne in June 1946 succeeding his brother, King Ananda Mahidol (Rama VIII), who had died under mysterious circumstances.

Wat Phra Kaew (Thai: วัดพระแก้ว, RTGS: Wat Phra Kaeo, pronounced [wát pʰráʔ kɛ̂ːw] ), commonly known in English as the Temple of the Emerald Buddha and officially as Wat Phra Si Rattana Satsadaram, is regarded as the most sacred Buddhist temple in Thailand. The complex consists of a number of buildings within the precincts of the Grand Palace in the historical centre of Bangkok. It houses the statue of the Emerald Buddha, which is venerated as the country's palladium.

Construction of the temple began in 1783 under the orders of Rama I, the first king of the Chakri dynasty. Since then, each successive king has been personally involved in adding, restoring and embellishing the temple during their reigns as a way of making religious merit and glorifying the dynasty. Many important state and royal ceremonies are held within the temple each year, presided by the king in person and attended by government officials. This makes the temple the nation's preeminent place of worship and a national shrine for the monarchy and the state. Throughout the years, each king has donated sacred and valuable objects to the temple, making it a treasury as well.
