  • The April 1933 Siamese coup d'état was an enforced change of government on 1 April 1933 by conservative and monarchist elites, led by Phraya Manopakorn Nititada (Phraya Mano), after the Draft National Economic Plan proposed by Pridi Banomyong, Khana Ratsadon's progressive leader, was deemed a communist threat by King Prajadhipok and Mano. It is considered to be the first coup in Thailand's history, followed by the first military coup two months later by Khana Ratsadon's army officer, Phraya Phahonphonphayuhasena.
