No previous monarch of Siam had ever spoken in such terms. Many interpreted the speech not as Prajadhipok apparently intended, namely as a frank appeal for understanding and cooperation. They saw it as a sign of his weakness and evidence that a system which perpetuated the rule of fallible autocrats should be abolished. Serious political disturbances were threatened in the capital, and in April the king agreed to introduce a constitution under which he would share power with a prime minister. This was not enough for the radical elements in the army, however. On 24 June 1932, while the king was at the seaside, the Bangkok garrison mutinied and seized power, led by a group of 49 officers known as "Khana Ratsadon". Thus ended 800 years of absolute monarchy.
