On July 7, 1929, the First Brazilian Eugenics Congress concluded in Rio de Janeiro. The congress brought together physicians, scientists, and intellectuals to discuss heredity, public health, and social improvement. It reflected the influence of international eugenics movements on Brazilian scientific and political thought at the time. Participants debated immigration policies, family structures, and national identity. Although the ideas promoted are now widely rejected, the event had a lasting impact on social policy discussions in Brazil.
