Royal Biography His Majesty King Prajadhipok (Rama VII)

His Majesty King Prajadhipok (Rama VII) was the seventh monarch of the Chakri Dynasty and played a significant role in the political and constitutional history of Thailand. He was the last monarch under the absolute monarchy and the first constitutional monarch.

His former title was His Royal Highness Prince Prajadhipok Sakdidejana, Prince of Sukhothai. He was the 76th son of His Majesty King Chulalongkorn and the ninth son of Her Majesty Queen Saovabha Phongsri. He was born on 8 November 1893 at the Sutthasri Apirom Throne Hall in the Grand Palace.

During his childhood, His Majesty received an education according to the traditions of the Royal Court before continuing his studies in England at Eton College and the Royal Military Academy, Woolwich, where he studied artillery. His experience of studying and living abroad provided him with an opportunity to learn about Western political systems, public administration, and democratic ideas, which later influenced his vision for the development of the country.

After completing his studies, His Majesty served in the British Army and was stationed at Aldershot. During this period, World War I broke out. He wished to join his British military classmates in battle on the Continent. However, King George V did not grant permission as he was a younger brother of His Majesty King Vajiravudh (Rama VI), and Siam was maintaining neutrality at the time. He was instructed to return to Siam.

Upon his return to Bangkok, His Majesty entered service in the Royal Thai Army as a Second Lieutenant. By 1917, he had attained the rank of Major and served as Commandant of the Junior Army Cadet School. Throughout his service, His Majesty carried out his duties with dedication and diligence and maintained a strong interest in the development of the country’s military affairs.

In 1917, His Majesty took leave from official duties to enter the monkhood at Wat Phra Si Rattana Satsadaram, taking the monastic name “Pachathipo.” He then resided for one Buddhist Lent at Wat Bowonniwet Vihara. This was in accordance with traditional royal customs and reflected his exemplary conduct and devotion.

On 26 August 1918, His Majesty married Her Serene Highness Rambhai Barni Svasti in a royal ceremony at Bang Pa-In Palace. They were the first couple in Siam to officially register their marriage. His consort was the daughter of His Royal Highness Prince Svasti, and Her Royal Highness Princess Abha Barni (née Gagananga). She was later elevated to the title of Her Majesty Queen Rambhai Barni. The royal couple carried out their royal duties together for the benefit and well-being of the people and the nation.

Following his accession to the throne on 26 November 1925, His Majesty faced challenges in both the economic and administrative affairs of the country during a period of rapid global change. Although he reigned under an absolute monarchy, His Majesty sought to gradually develop the system of public administration and promote greater public participation. He laid foundations for local administration, modern public administration, and preparations for a transition to constitutional government.

When the change in government took place on 24 June 1932, His Majesty chose a peaceful approach in order to maintain peace and stability in the country. On 10 December 1932, he granted the first permanent constitution to the Thai people, marking an important milestone in the development of Thailand’s democratic system.

Although differences later arose regarding the direction of the country’s administration, His Majesty remained committed to the fundamental principles of governance that respected the rights, freedoms, and equality of the people. This ultimately led to his decision to abdicate the throne on 2 March 1934. In his royal letter of abdication, he stated:

“I am willing to relinquish the powers which I formerly exercised to the people as a whole. However, I do not consent to surrender all my powers to any individual or any particular group, to exercise those powers absolutely and without heeding the true voice of the people.”

Following his abdication, His Majesty resided in England and passed away on 30 May 1941 at Compton House, Virginia Water, Surrey, England, from heart failure, at the age of 47.

Throughout his life, His Majesty King Prajadhipok devoted himself to the benefit of the nation and played an important role in laying the foundations for Thailand’s transition toward constitutional government. His royal contributions continue to have a lasting significance for the development of Thailand and Thai society to the present day.
