Abstract
Our goal is to understand the appearance and spread of forms of puerperal insanity in Argentina and Colombia in the late nineteenth and early twentieth century, as well as their decline or disappearance around the 1940s. This is a historical and hermeneutical study, which uses the concepts of “field of visibility” and “ecological niche” for a transitory disease. There was no correlation between pregnancy, childbirth and puerperium and the state of delirium that led to commitment, which was attributed to predisposing factors; furthermore, forms of puerperal insanity were nosographically distinct due to their unique etiopathogeneses. As clinical cases of puerperal insanity started to emerge, the disciplinary field of obstetrics converged with psychiatry, with the former exerting more weight.
