This article examines the process of drafting the authoritarian Portuguese Constitution of 1933, which took place during the military regime. The aim is to identify the powers involved, their objectives and the strategies they developed, and to find insights that shed light on the adoption of constitutions by authoritarianisms. The results suggest that conflict between political forces is endemic to the constitutional process, and that those who hegemonise support and aim to demilitarise the system are able to impose the new constitution even without guaranteeing the existence of democratic political parties. There is also a promising point of analysis: the emergence of an authoritarian constitution is based on path dependence, ie, it has many links with the material constitutionalism that precedes it, where there are already normalised authoritarian elements.
