The history of science is necessary for the process of doing science. The history of science is not just the result of strictly scientific processes. In this regard, our intention with this text is to look at the Association of Brazilian Geographers (AGB) and its role in professional training, its importance in the elaboration, appropriation, and dissemination of ideas of/in geographical science in Brazil, and in the definition of the agenda of struggles of the geographical community itself in Brazil. These processes are the result of what the history of geography itself has handed down to us: the great proximity between the AGB and the transformations perceived in the science of geography and Brazilian society in the years subsequent to 1934. In this regard, we discuss the ways, means, and processes which have given the AGB a prominent role within this scientific community in Brazil, and thereby attempt to understand to what extent and in what way the AGB and the movement surrounding it have been responsible for consolidating Brazilian geography, for a geography of struggle. It can also be asserted that without the existence, ideas, practices, interventions, and transformations of the AGB, since 1934, upon its creation; since 1946, with the holding of its assemblies in different parts of the country; since 1972, with the holding of its first mass event; since 1979, with its more radical and democratic transformation, the history of geography in Brazil would have been very different. The AGB, born in the previous century, is an expression of the phenomenon of the social history of geography in Brazil. Its emergence and subsequent development are the result of a specific conception of geography, of a long institutional history within Brazilian geography. The AGB is not only the bearer of a certain professional institutionality, it is a moving entity, but also a space where science is developed as knowledge in the service of the transformation of society and the geographical space, in line with the philosophy of praxis. This is why in recent years the AGB has been a growing space with an active and vibrant presence of social movements which, in dialogue with the geographies, day by day are constructing more committed geography, a geography of struggle.
