Anarchists' pursuit of indigenous emancipation in Peru has been obfuscated and largely erased in Peruvian historiography. This is attributable in part to a concerted effort by Marxists and national populists (Apristas) to minimise anarchist influence and to arrogate to themselves the role of true defenders and revolutionary allies of Peru's indigenous peoples This article examines the way anarchists understood the nature of Peru's system of domination and the multifarious ways it oppressed, exploited, and marginalised indigenous peoples. They recognised the imperative to overcome urban-rural and coastal-sierra divisions to empower indigenous workers and peasants and to forge multi-ethnic alliances. In doing so, they fostered indigenous syndical organisations, encouraged the formation of indigenous intellectuals and activists, promoted bilingual education, and established study centres and rural schools. They defended indigenous and multi-ethnic communities' rights to land and resources and supported their demands for self-governance. That they were unsuccessful in achieving indigenous emancipation does not negate the important legacy of solidarity and struggle they bequeathed to Peru's current anarchist movement.
