This article aims to propose a reflection on the representations of masculinity circulating in Bogotá during the first half of the 20th century and its articulation with the national project and the model for family intended to be imposed. In that sense, the study addresses the research question, which were the representations of masculinity circulating in Bogotá during the first half of the 20th century and their influence on family and nation? To answer it, a first objective is to approach the analysis of the concept of masculinities, highlighting that this term was coined after the studied period of time, but that nevertheless is useful as an element of analysis in order to understand the different gender roles society assigns in each era. A second objective is to review the State-Nation project intended to be developed since the 19th century and the revitalization such a project had during the first half of the 20th century; this with the goal of a consolidation of a national identity. The third objective addresses the family typologies and their legal representations, developed from rites as the Catholic and civil marriage-institutions that, in addition, were mandatory, hegemonic, hetero centered, and andro-centered. In order to fulfill these objectives, a documental research methodology was implemented, trawling through different written documents available in archives and libraries in the city. Secondly, the information was systematized using an indexing technique, where a specific nomenclature for the analysis and assessing of texts was proposed. Then, the written version of the research started to be developed, one that allowed important findings when examining how these different elements were articulated, reproducing a discourse of gender differentiation and some masculine roles associated with the ideas of strength, heroism, and virility, where these features had to represent, furthermore, the ideal of the nation.
