Because of historical amnesia reinforced through schooling, peoples who are marginalized on the basis of race, ethnicity, and immigration have often learned to accept rather than challenge that marginalization. This chapter shows how ethnic studies in U.S. elementary and secondary schools attempts to combat the historical amnesia schooling perpetuates regarding colonialism and racism. The chapter reviews processes that diluted how many people understand multicultural education, and how that diluted understanding is reflected in white-dominant curricula. After discussing ethnic studies as a decolonial project, the chapter presents two examples, highlighting their impact on students. The chapter concludes with implications.
