LECCIONES (PRELIMINARES) DE CIENCIA CONSTITUCIONAL. INSUMOS PARA EL ESTUDIO DE LA OBRA DE JUAN FÉLIX DE LEÓN, DENTRO DEL CONSTITUCIONALISMO COLOMBIANO DE FINALES DEL SIGLO XIX^*/**

In 1877, Professor Juan Félix De León published the work Lecciones de Ciencia Constitucional (Lessons in Constitutional Science), which studies the constitutional law of the 19th century. Based on it, this article proposes, from a genealogical methodology, a historical-interpretative reconstruction of the Constitution of the United States of Colombia (1863) regarding the issues of carrying and trading of weapons and constitutional reform. To this end, it contains a study of the context in which the work was published, the professional life of Professor De León and the contents of the book Lecciones de Ciencia Constitucional.
