This article features the museums of Oaxaca, the place where the community museum movement in Mexico got started. Oaxaca has the largest Indigenous population in Mexico, with about 36.6% of the population over five years old, or about 1.027 million people, speaking an Indigenous language. Tourists spend large amounts on group or personalized tours and flock to it to try to get a closer look at the "real" Oaxaca and to experience the richness of Mexico's Indigenous cultures, layered together from the present day back to pre-Columbian times. Community museums have proved to be a way for the towns to construct and transmit their identities through the choice of themes important to the communities, in which archaeology is chosen as one of the themes of their museum. In Oaxaca the museums have been a way for the small communities to assume control of the stewardship of the archaeological treasures found: they stay in the community because they are culturally meaningful for that population, and in addition, their display in museums in the community raises funds for the community, albeit a small amount. Here, the author discusses the creation of community museums in Mexico and the decolonizing mission of these museums, and describes how community museums can have a great impact on the decolonization of a region in a way that is inspiring and instructive.
