Boworadet Rebellion The Boworadet Rebellion ( Thai : กบฎบวรเดช ; RTGS : Kabot Boworadet ) was a Thai rebellion ( or unsuccessful " coup d ' état " ) led by royalist Prince Boworadet in 1933 , in consequence of the conflicts between the previous royalist regime and the succeeding constitutional regime following the Revolution in 1932 . The Boworadet revolt was eventually defeated by the Siamese Government . As a historical event it was cataclysmic in the transformation of Thai politics and government . Background . In March 1933 , Pridi Phanomyong , a Minister of State and a member of the People ' s Party , was attacked verbally by the constitutional monarch King Prajadhipok ( or King Rama VII ) as a communist following the proposal of the Draft National Economic Development Plan , or the " Yellow Cover Dossier " , to the National Assembly . The Yellow Paper was a plan to arrange and provide State welfare , to distribute all land to the rural poor , to interfere in economic affairs of the private sectors and to provide rural farmers more economic subsidies . These concepts were deemed communistic ( or at least socialistic ) by the Monarch . This led Thawan Ritthidet ( Thai : ถวัลย์ ฤทธิเดช ) , a private citizen , to file a lawsuit against the King , accusing him of intervention in political , state and economic affairs . The fallout over Pridi ' s plan divided the Cabinet and led the Prime Minister , Phraya Manopakorn Nititada , to dissolve the National Assembly on the 1 April and use emergency decrees ( such as the Anti - Communist Act ) to govern . Pridi was immediately exiled to France . On the 20 June , a senior Army Officer and member of the Khana Ratsadorn or the People ' s Party , General Phraya Phahon Phon Phayuhasena ( Thai : พลเอก พระยาพหลพลพยุหเสนา ( พจน์ พหลโยธิน ) ) , seized power in a coup d ' état , overthrowing the Government of Phraya Manopakorn . The coup leader appointed himself the second Prime Minister of Thailand , declared Pridi Phanomyong not guilty and allowed him to returned . Prince Boworadet . Prince Boworadet ( Thai : พระเจ้าบรมวงศ์เ้ธอ พระองค์เจ้าบวรเดช ) , a German - educated minor member of the Royal Family , had been Minister of Defense and the Siamese Ambassador to France . He lost his positions following the Revolution of 1932 . An ardent royalist , he was furious that anyone was allowed to sue the King . This added to his discontent of Phraya Phahon Phon Phayuhasena ' s coup against Phraya Manopakorn and his support of Pridi against the monarch . Prince Boworadej secretly plotted with Colonel Phraya Sri Sitthi Songkhram ( Thai : พระยาศรีสิทธิ์สงคราม ) , commander of the Armed Forces of Bangkok , and other senior military officers to stage a coup d ' état to unseat the government and replace it with a more traditional one . When the Khana Ratsadon ( People ' s Party ) took over , the older right - wing military officers had been unceremoniously pushed out and replaced by younger coup members . On 11 October 1933 , Prince Boworadet led royalist forces from the Eastern Region of the Country , consisting of the Korat , Phetchaburi , and Udon Regiments , together with a cavalry unit and several artillery batteries . They reached the capital to find that the military units in Bangkok supported the government . He nevertheless continued the attempt . Suppression of the Rebellion . The first clash occurred on 11 October 1933 at Amphoe Pak Chong , in Nakhon Ratchasima Province . The government forces were defeated and several members of the government were captured . The rebels then marched to Bangkok ' s Khet Don Mueang , calling themselves the " National Rescue Council " ( Thai : คณะกู้บ้านเมือง ; RTGS : Khana Ku Ban Mueang ) and their attempt the " Deer Plan " ( Thai : แผนล้อมกวาง ; RTGS : Phaen Lom Kwang ) . Prince Boworadet tried to persuade other forces to join him , including the Royal Thai Navy , which instead declared itself neutral and sailed for bases in the South . The ' royal ' government as it declared appointed Lieutenant Colonel Luang Phibulsonggram , one of the 1932 coup makers , to command the Bangkok forces . These were supported by an armoured car and a tank commanded by Pibun ' s friend , Lieutenant Colonel ' Luang Amnuai Songkhram ( Thom Kesakomon ) ( Thai : หลวงอำนวยสงคราม ( ถม เกษะโกมล ) ) , who would later be killed in combat . After a day of fierce fighting on 12 October , the rebels were able to capture Don Muang on the outskirts of the city . Major Luang Seri Somroeng Rit ( Thai : พันตรีหลวงเสรีเริงฤทธิ์ ) was appointed ( under truce ) to ask the rebels to surrender , under a government offer of amnesty . However , the Major was seized and made a hostage . The rebels presented the following demands : 1 ) the Country shall be headed by the King forever ; 2 ) all State affairs must be carried out in accordance with the Constitution , especially the appointment and removal of a member of the Council of Ministers , which can only be made by a majority of votes ; 3 ) Permanent public officials , both civil and military , shall not intervene in politics ; 4 ) The appointment of public officials shall be made with regard qualifications , without political partiality ; 5 ) The second type ( non - elected ) of the people ' s representatives shall be appointed by the King ( as opposed to the Prime Minister ) ; 6 ) Armaments for the Army shall be provided everywhere , not gathered in any specific area ; 7 ) Amnesty shall be granted to the National Rescue Council and all its supporters . The official ' Royal Siamese Government ' in Bangkok refused to comply with the their demands , and the rebel forces advanced further to the capital , seizing the area around Bang Khen . The rebels set up a stronghold near the Lak Si train station , using machine guns and cavalry . The government was able to drive the rebels with the help of the Nakhon Sawan Regiment and a declaration of the Prachinburi Regiment in support of the government and join the fight . This broke of the rebels ' morale , and on 14 October they began to retreat . The next day the government with superior forces ( heavy artillery having been moved in by rail ) was able to attack the rebel stronghold . Running out of ammunition and supplies , the rebels broke . Government forces pursued and advanced to the rebel base in Nakhon Ratchasima . On 23 October , with the possibility of further reinforcement by other provincial garrisons and the death in action of Boworadet ' s second - in - command , Phaya Sri Sitthi Songkram , the rebels were badly defeated . The remnants dispersed , and the revolt was over . Aftermath . Much destruction was done to the infrastructure of Bangkok ( railways and bridges ) and the surrounding area , including the Don Mueang Aerodome , from artillery bombardment , bombings and fire . On 25 October Prince Boworadet and his wife boarded an aeroplane and left Siam for Vietnam ( then part of French Indochina ) . Many other leaders were arrested or surrendered , including Prince Boworadet ' s younger brother , Prince Sinthiphorn Kadakorn ( Thai : หม่อมเจ้าสิทธิพร กฤดากร ) . The rest were eventually suppressed and were tried by a special court . Many received life sentences , but none were executed . Most sentences were later reduced and many were pardoned completely . Prince Boworadet received asylum in Cambodia , where he lived until 1948 . He then returned home to Thailand , dying in 1953 at the age of 76 . Legacy . As the victorious faction Phraya Phahol ' s Government was able to further cement their grip on power , moving ever closer to a dictatorship using the military as a tool . Even though there is no evidence that Prajadhipok ever supported the rebellion , the result was nevertheless a blow to the King , as his prestige was greatly diminished and his power severely weakened . The King ' s lack of leadership and indecisiveness showed when he only released a telegram saying that he regretted the strife and civil disturbances that occurred , he and the Queen then left the capital for Songkla leaving the Government to deal with the rebellion . During this time he also failed to support his constitutional Government morally , which undermined his credibility and his perceived commitment to democracy and the constitutional system . This gave Phraya Phahol and the King ' s opponents reason to point that the monarch has failed to do his duty . The series of events following the rebellion eventually led to the King ' s abdication in 1935 . The rebellion also led to the estrangement of the aristocratic factions and families , which has served the Kingdom for centuries . They were viewed with distrust and would never again regained their power and position in Thai politics . The rebellion was also seen as a beginning of the meteoric rise of the two key players in the rebellion : Pridi and Phibul . Pridi , eventually became leader of the civilian faction within the Government and later Regent for King Ananda Mahidol ( or Rama VIII ) from 1944 – 1946 and then eventually Prime Minister in 1946 . Phibul became the new leader and hero of the military faction and replacing Phraya Phahol as Prime Minister from 1938 – 1944 and then later 1948 – 1957 , and eventually de facto dictator of Thailand ( to date the longest serving Prime Minister in Thai history ) . The " Rebellion Suppression Monument " was established at Khet Lak Si , Bangkok , as a commemoration of this event , and later renamed as the " Constitution Defense Monument " .
