This article addresses the legal and political background of the 1991 Political Constitution of Colombia, the historical context in which it arose and the changes it entailed in the constitutional order, as well as the different reforms that have been made to it during three decades of validity. The reader will be able to recognize that Colombian constitutionalism has been characterized by a recurring constitutional inflation and that the 1991 Constitution, despite having represented notable advances in the face of the consolidation of the constitutional rule of law, has not been immune to this phenomenon and almost equates in number of amendments to the 1886 Charter, which was in effect for 105 years. To achieve this, a hermeneutical method of the social, legal and political sciences is applied that allows interpreting social and political phenomena, as well as sources of law, accompanied by the use of documentary, information and discourse analysis techniques, to the processing of data obtained, mainly, from bibliographic sources and formal sources of law.
