Modern Thai constitutionalism, though often meaningful and rich in form and substance, has experienced great volatility since its inception in 1932. At the same time, behind the twenty constitutions that have emerged since then, some recurring ideal-typical figurations that have dominated certain periods of constitutional politics in Thailand can be observed. These historically derived ideal-typical notions of constitutional politics mostly represent inherently hegemonic conceptions. They are defined for instance by how they conceive western and autochthonous elements of constitutionalism, majoritarian electoral politics and the monarchy, the rule of law and authoritarian governance by men. This chapter explores some of the most significant historical experiences and ensuing figurations of Thai constitutionalism that together form a rich reservoir of different, sometimes diverging notions to understand and practice constitutional governance in Thailand.
