Indigenismo is a Latin American nationalist political ideology that began in the late nineteenth century and persisted throughout the twentieth that attempted to construct the role of Indigenous populations in the nation-state. The ideology was particularly influential in Mexico where it shaped the majority of Indigenous-state relations since its incorporation into the Constitution in 1917. While the perspectives and methods of Indigenistas changed and adapted over time, the defining features of Mexican Indigenismo are the implementation by primarily non-Indigenous actors, the celebration of Indigenous culture as a part of the nation's history, and the attempt to integrate Indigenous populations under the authority of the nation-state. The ideology was enacted by a number of policies, institutions, governmental programs, and through artistic expression. These included education programs, land reform, political reform, and economic development as well as national displays of Indigenous heritage. Although generally viewed as beneficial for creating a platform to discussing Indigenous issues, Indigenismo has been criticized as still operating under colonial paradigms of racial hierarchy and often helped to solidify some stereotypes of Indigenous peoples even while trying to break down others.
