Araucanization is a process that refers to the cultural and linguistic assimilation of indigenous peoples of South America, particularly in Chile and Argentina, with the Mapuche people. There are several synonyms for Araucanization, including Mapuchization, Mapuchization process, Chileanization, and Indianization. These terms refer to the process of cultural and linguistic assimilation of indigenous peoples into the dominant culture of a region. The process has been criticized for erasing the unique cultures and languages of these indigenous peoples. However, efforts are underway to promote the preservation and revitalization of indigenous languages and cultures to prevent the disappearance of their heritage and identity.
