Khana Ratsadon

The promoters

In 1927, the Kingdom of Siam was under the absolutist rule of the House of Chakri, under King Prajadhipok, Rama VII. Under his reign, the nation experienced troubles stemming from an archaic government confronted with serious economic problems and threats from abroad, the British and French Empires. The country was also experiencing a dramatic social change as the urban and middle classes of Bangkok were starting to grow, slowly demanding more rights from their government, criticizing it as ineffective. These changes were mostly led by men, civilians and military, who had graduated or travelled abroad. They wanted to transform Siam into a modern country along the lines of a Western Democracy.

In February 1927, a group of seven Siamese students met at a hotel on the Rue Du Sommerard in Paris and founded what would become the Khana Ratsadon. For five days they met and proposed arguments for and against various aspects of the movement, the men were:

1. Lieutenant Prayoon Pamornmontri (Thai: ร.ท. ประยูร ภมรมนตรี), Army officer, formerly of King Vajiravudh's Royal Guards

2. Lieutenant Plaek Khittasangkha (Thai: ร.ท. แปลก ขีตตะสังคะ), later Luang Phibulsonggram, Army officer, student, School of Applied Artillery, France

3. Lieutenant Thatsanai Mitphakdi (Thai: ร.ต. ทัศนัย มิตรภักดี), Army officer, student, French Cavalry Academy

4. Tua Lophanukrom (Thai: ตั้ว ลพานุกรม), Scientist studying in Switzerland

5. Luang Siriratchamaitri (Thai: หลวงสิริราชไมตรี), Diplomat, officer at the Siamese Embassy in Paris

6. Naep Phahonyothin (Thai: แนบ พหลโยธิน), Law student studying in England

7. Pridi Banomyong (Thai: ปรีดี พนมยงค์), Law student studying at the Institut d'Études Politiques de Paris)

Six principles

A school notebook published in 1934, with illustrations of the six principles on its cover, displayed at Thai Parliament Museum, Bangkok.

The revolutionaries made Pridi Panomyong their president and termed themselves the "promoters" (Thai: ผู้ก่อการ; RTGS: Phu Ko Kan). The party determined a sixfold objective which was later called the "Six Principles" (Thai: หลักหกประการ; RTGS: Lak Hok Prakan), as follows:

1. To maintain the supreme power of the Thai people.

2. To maintain national security.

3. To maintain the economic welfare of the Thai people in accordance with the National Economic Project.

4. To protect the equality of the Thai people.

5. To maintain the people's rights and liberties, insofar as they are not inconsistent with any of the above-mentioned principles.

6. To provide public education for all citizens.

To achieve these goals, the party determined that they must overthrow, using force if necessary, the present government and the system of absolute monarchy and turn the Asian kingdom into a modern constitutional monarchy. Most of the members were students educated abroad, mostly in the United Kingdom and France.

When the group returned to Siam, they enlisted members from among the army and navy, the merchant class, civil servants and others. Their membership eventually reached 102, separated into four main branches. These included the civilians, led by Pridi Banomyong; the navy, led by Luang Sinthusongkhramchai; the junior army officers, led by Major Phibulsonggram; and finally the senior officers, led by Colonel Phot Phahonyothin
