Prajadhipok

Prajadhipok, also known as Rama VII (8 November 1893 – 30 May 1941) was the seventh monarch of the Chakri dynasty and the last king of Siam under the absolute monarchy. He ascended the throne in 1925 and reigned until his abdication in 1935 during his self-imposed exile following his fallout with the new democratic government after the 1932 Siamese Revolution, which brought an end to the country’s absolute monarchy.

Born during the reign of King Chulalongkorn, Prajadhipok was the youngest son of Chulalongkorn and Queen Saovabha Phongsri. He succeeded his brother, King Vajiravudh, and pursued significant reforms, including establishing the Privy Council, modernizing financial and public-utility regulations, advancing municipal administration, founding the National Library, expanding university education, establishing the Royal Institute, and commissioning the complete Thai-script edition of the Tripitaka. However, his rule was also marked by weak political leadership and turbulent economy due to the Great Depression, leading to the revolution in 1932. After a failed royalist reactionary revolt in 1933, he went into a self-imposed exile in Britain and later abdicated.

Following his abdication, Prajadhipok and Queen Rambai Barni settled in England and never returned to Siam. As he left no heirs, the cabinet and parliament invited his young nephew Prince Ananda Mahidol to become king at age nine, marking the rise of the Mahidol branch. After Ananda's death in 1946, his brother Bhumibol Adulyadej (Rama IX) succeeded him.

UNESCO has acknowledged the historical importance of documents and artifacts related to King Prajadhipok's reign. His personal collection of photographs and films documented Siam's transition. Additionally, "The Minute Books of the Council of State of Siam (1893–1932)", which include records from his time, are listed on the UNESCO Memory of the World Register. UNESCO has also recognized him as a "great personality" in commemorations.
