The text1 discusses the history of day care centers in Amazonas under the Projeto Casulo of Legiao Brasileira de Assistencia (LBA) between 1979, when the first daycare center opened, and 1990, the year in which the LBA reached 61 municipalities in the state. We assume that these day care centers emerged in a context of mass projects for children up to the age of six, implemented at a low cost, in collaboration with multilateral organizations, meeting Unicef requirements, such as the reduction of needs in material and cultural spheres, through the proliferation of these institutions throughout the country. We use the historical method with a social and cultural approach, having as procedures and instruments: documentary research, through journals, official and non-official documents, interviews, and oral reports. The findings reveal that the expansion of the day care centers occurred directly through operational units of direct execution, managed by the LBA, and indirectly through accredited operational units, in accordance with the National Security Doctrine -DSN.
