Content:   According to the 2007 Constitution, the cabinet instructed the president of the National Assembly to invite Crown Prince Vajiralongkorn to the throne. He became the first monarch to be born in Thailand since his great-uncle Prajadhipok. After his father, Bhumibol Adulyadej, died on 13 October 2016, Vajiralongkorn was expected to succeed to the throne of Thailand but asked for time to mourn before taking the throne. On the night of 1 December 2016, the fiftieth day after the death of Bhumibol, Regent Prem Tinsulanonda led the heads of the country's three branches of government to an audience with Vajiralongkorn to invite him to ascend to the throne as the tenth king of the Chakri dynasty. Vajiralongkorn accepted the invitation, saying in a televised statement: "I would like to accept in order to fulfill his majesty's wishes and for the benefit of all Thais." The government retroactively declared his reign to have begun upon his father's death, but it would not crown him formally until after the cremation of his father. The remains were then cremated on 26 October 2017. Currently, his main residence is Amphorn Sathan Residential Hall, with the king having moved from Nonthaburi Palace in 2011.

Content:  Vajiralongkorn married for a third time on 10 February 2001, to Srirasmi Suwadee (royal name: Akharaphongpreecha), a commoner of modest background who had been in his service since 1992. The marriage was not disclosed to the public until early 2005. She gave birth to a son, Prince Dipangkorn Rasmijoti, on 29 April 2005 and was then elevated to the rank of princess. Her son was immediately elevated to the rank of prince. In a magazine interview shortly after that, Vajiralongkorn stated his intention to settle down. In November 2014, however, Vajiralongkorn sent a letter to the interior ministry asking for Princess Srirasmi's family to be stripped of the royal name Akharaphongpreecha awarded to her, following allegations of corruption against seven of her relatives. The following month, Srirasmi relinquished her royal titles and the royal name and was officially divorced from Vajiralongkorn. She received 200 million baht (US$5.5 million) as a settlement. They had been married for 13 years.

Content:  On 3 January 1977, Vajiralongkorn married Princess Soamsawali Kitiyakara (born 1957), a first cousin on his mother's side. They had one daughter, Princess Bajrakitiyabha, born in 1978. Crown Prince Vajiralongkorn started living with actress Yuvadhida Polpraserth in the late 1970s and had five children with her. Although Princess Soamsawali had refused divorce for many years, Vajiralongkorn was finally able to sue for divorce in the Family Court in January 1993. In the court proceedings, Vajiralongkorn accused Princess Soamsawali of being completely at fault for the failed relationship. She was not able to refute the charges due to the prohibition against lèse majesté. The divorce was finalized in July 1993. Princess Soamsawali and her daughter continue to play a significant role in royal ceremonies.

Content:  Most of the time, Vajiralongkorn lives in Bavaria in Germany, where he has spent a significant amount of his adulthood. His 15-year-old son, Dipangkorn Rasmijoti, goes to school in the area. The King requested and received changes to the constitution to end the requirement that he appoint a regent when he is away from Thailand. In comparison, his father often made state visits early during his reign, but he left the country only once after the 1960s—an overnight stay in neighboring Laos. He has also received visits from Thai officials and dignitaries in Germany. According to the German foreign ministry, the Thai ambassador has been told multiple times that Germany opposes "having guests in our country who run their state affairs from here." Thai officials have told Germany that Prime Minister Prayut is responsible for government matters, while the King is in Germany for personal reasons.
