Present-day political systems in the nation states of Southeast Asia can be classified in accordance with various criteria; they can, for example, be politically grouped on a spectrum ranging from parliamentary democracy to totalitarian dictatorship. The focus of the present inquiry is the sociology of political elites rather than the forms of polity which these elites have created or helped to create. It deals exclusively with the ruling “national” elites, leaving out of consideration secondary groups, such as territorially- or ethnicallybased local and regional elites, religious leaders, and other traditional elites. Two kinds of “national” elite can be discerned in contemporary Southeast Asia, which we shall call “intelligentsia elites” and “modernizing traditional elites”. Disregarding for the time being the constitutional frameworks and the degree of popular participation of each individual state, it may be said that both elites are in many respects oligarchies.
