absolute monarchy and bring a constitutional government to the kingdom. Their efforts culminated in an almost bloodless "revolution" on the morning of 24 June 1932 by the self-proclaimed Khana Ratsadon (People's Party; คณะราษฎร). While Prajadhipok was away at Klai Kangwon Palace in Hua Hin, the plotters took control of the Ananda Samakhom Throne Hall in Bangkok and arrested key officials (mainly princes and relatives of the king). The People's Party demanded Prajadhipok become a constitutional monarch and grant Thai people a constitution. In the event of a negative response, they reserved the right to declare Siam a republic. The king immediately accepted the People's Party's request and the first "permanent" constitution of Siam was promulgated on 10 December. Prajadhipok returned to Bangkok on 26 June and received the coup plotters in a royal audience. As they entered the room, Prajadhipok greeted them, saying "I rise in honour of the Khana Ratsadorn." It was a significant gesture because, according to previous royal rituals, monarchs were to remain seated while their subjects made obeisance, this showed that Prajadhipok was acknowledging the changed circumstances. First constitutional monarch In the early stages of the constitutional monarchy, the King and the royalists seemed to be able to compromise with Khana Ratsadon. The constitutional bill which was drafted by Pridi Banomyong and intended to be a permanent one was made temporary. The new constitution restored some of the monarch's lost power and status. Among them were introduction of unelected half of the House of Representatives and royal veto power. The country's first prime minister Phraya Manopakorn Nititada was a conservative and royalist nobleman. The compromise broke down quickly. He did not contest when his interpretation of Pridi's economic plan, which also aim on land reform and seizure of royal land, was released with his signature. The king played a role in the coup d'état of April 1933 where the House was ordered to close by the Prime Minister. He signed an order to execute Khana Ratsadon leaders. But Khana Ratsadon's military wing leader Phraya Phahol Phonphayuhasena ousted the government and restored its power. He played an active role in an anti-revolutionary network, which also aimed to assassinate Khana Ratsadon's leaders. In October 1933, the maverick Prince Boworadej, a former minister of defence, led an armed revolt against the government. In the Boworadet Rebellion, he mobilised several provincial garrisons and marched on Bangkok, occupying the Don Muang
