This article analyses a complex period in Colombian history, from the electoral victory of the Liberal Party in 1930 to the end of the Frente Nacional (National Front) in 1974, from the perspective of constitutional politics and constitutional theory. During this period, Colombia transited from democracy to dictatorship (civilian and military) and back to democracy. We therefore divide the period according to changes in regime type and also to changes in the degree of institutional constraints on power. We show that, due to combinations of regime type and constraints on power, under the same Constitution of 1886 three different constitutionalisms ensued: abusive, window-dressing, and authoritarian constitutionalism. Our analysis on Colombia highlights the role of powerful actors, such as the armed forces and the Catholic Church, that breathed life back into key constitutional provisions when these served as focal points for coordinating their actions even under an authoritarian regime.
