This article examines the relationship between collective memory and individual second-language (L2) learning motivation as articulated in a qualitative research study with language revitalization practitioners. These practitioners learn and teach their languages and engage in other activities in order to bring Indigenous or ancestral languages into new use following a period of loss. In this study, 28 revitalization practitioners from eight language communities were interviewed about why they choose to learn their languages, what challenges they face, and what supports them in their practice. Interviews were first analyzed using inductive thematic analysis and were subsequently analyzed deductively to engage with research on the functions of autobiographical memory. Findings show how collective memories are made salient in the language revitalization experience, how individuals grapple with painful memories of what their communities and families endured as a result of colonization, and how these collective memories impact individual L2 motivation. These findings illustrate the importance of collective memory in theorizing L2 motivation in order to enhance understanding of context, dismantle overly individualistic interpretations of L2 motivation models, and open avenues for critically engaging with historical trauma and resistance.
