Born in 1925 in Heidelberg, Germany, Ananda Mahidol became the first Thai monarch to enter the world outside his home country. In March 1935, at age nine, the National Assembly recognized him as the eighth king of the Chakri dynasty, known as Rama VIII, while he resided in Switzerland for his education.
Early Life and Succession
The son of Prince Mahidol Adulyadej and Mom Sangwan, Ananda Mahidol returned to Thailand in 1928 following his father's medical studies at Harvard. After his father died in 1929, he attended schools including Debsirin and Mater Dei. Concerns regarding his safety after the 1932 revolution prompted his return to Switzerland in 1933. Following the 1935 abdication of his uncle, King Prajadhipok, the cabinet and National Assembly favored Ananda Mahidol's selection as monarch, viewing his youth and overseas residence as practical for the new constitutional government.

Return and Unexpected Death
Ananda Mahidol returned to Thailand in December 1945. His reign ended abruptly on 9 June 1946 when he was discovered shot dead in his bed at the Boromphiman Residential Hall.
