This is, first of all, a study on how Thai modern system of education with lt new outlook,: model, and management of state school network developed during the years 1868 – 1932. It is, secondly, an attempt to study how such a system affected the structure of the Thai society and, how it helped bringing about the abolition of the form of the very governmentwhich it was originally supposed to serve. The basic premise of this study is that the main. function of any education system is to socialize its people to prepare them to live according to the established norms of the society. When Thailand faced With the threat of' colonialism from the West, went through its course of political and administrative reform; the traditional education system had to give way to the new one. Through the new education system and school network, the government of King Rame V consciously tried to instill among the people the sense of nationhood and the spirit of citizenship, with' the monarchy as the unifying point; The new system of higher education which aimed primarily at training civil bureaucrats to man the newly’ found civil service was. highly successful. But in so doing the expansion of vocational education with 1.its possible link to future economic development was unfortunately neglected. With the rapid growth of' the bureaucratic system, the civil bureaucrats developed into a distinctive social class, and had become increasingly restive. When socio-economic problems later hit Thailand, the conflict between the new bureaucrats and the royal power became inevitable. In 1932 the new class of civil bureaucrats turned into some sort of a new political force with the young leaders as its spearhead. The result was-the revolution which once and for all overthrew, the absolute monarchy and started Thailand on its new course of political development.
