Abstract
This article analyzes healthy child contests as a medical and socio-political strategy implemented in Latin America to protect childhood, thus ensuring the future of the "race" and the nation. These contests blended degeneration, racial theories, and state interventionism and gained momentum in the 1930s with the rise of eugenics. This article examines the contest in Colombia, which was implemented under the Liberal Republic (1930-1946); even though this competition was defined by its national context, a broader international perspective improves understanding. Questions are also raised about the efforts of the Liberal government to strengthen the idea of national identity through education and health programs.
