On 24 June 1932, a group calling themselves the Khana Ratsadon (or People's Party), together with the military, seized power in Bangkok. They abolished the system of absolute monarchy, changing Siam into a parliamentary constitutional monarchy and demanding of Prajadhipok a constitution for the people of Siam. The king granted them a "temporary" constitution in the same month and a permanent one in December. The Khana Ratsadon, once in power, abolished the Supreme Council and the Privy Council. They replaced the Council of Secretaries with the People's Committee of Siam.
