Siam to Thailand (1939–1946) Rise of Phibunsongkhram The military, now led by Major General Phibun as defence minister, and the civilian liberals led by Pridi as foreign minister, worked together harmoniously for several years, but when Phibun became prime minister in December 1938 this co-operation broke down, and military domination became more overt. Phibun was an admirer of Benito Mussolini, and his regime soon developed some fascist characteristics. In early 1939 forty political opponents, both monarchists and democrats, were arrested, and after rigged trials eighteen were executed, the first political executions in Siam in over a century. Many others, among them Prince Damrong and Phraya Songsuradej, were exiled. Phibun launched a demagogic campaign against the Chinese business class. Chinese schools and newspapers were closed, and taxes on Chinese businesses increased. Phibun and Luang Wichitwathakan, the government's ideological spokesman, copied the propaganda techniques used by Hitler and Mussolini to build up the cult of the leader. Aware of the power of mass media, they used the government's monopoly on radio broadcasting to shape popular support for the regime. Popular government slogans were constantly aired on the radio and plastered on newspapers and billboards. Phibun's picture was also to be seen everywhere in society, while portraits of the ex-monarch King Prajadhipok, an outspoken critic of the autocratic regime, were banned. At the same time Phibun passed a number of authoritarian laws which gave the government the power of almost unlimited arrest and complete press censorship. During the Second World War, newspapers were instructed to print only good news emanating from Axis sources, while sarcastic comments about the internal situation were banned. Fascist Thailand On 23 June 1939, Phibun changed the country's name from Siam to Prathet Thai (), or Thailand, said to mean "land of the free". This was a nationalist gesture: it implied the unity of all the Tai-speaking peoples, including the Lao and the Shan, but excluding the Chinese. The regime's slogan became "Thailand for the Thai." Cultural Revolution Modernisation was also an important theme in Phibun's new Thai nationalism. From 1939 to 1942 he issued a set of twelve Cultural Mandates. In addition to requiring that all Thais salute the flag, know the national anthem, and speak the national language, the mandates also encouraged Thais to work hard, stay informed on current events, and to dress in a Western fashion. By 1941 it became illegal, among other things, to
