This article explores the racial prerequisite cases, which were dubious court decisions that attempted to rationalize pseudo-"scientific evidence" and "common knowledge" as reasons for who could and could not be considered for, and who was ultimately denied, U.S. citizenship. These cases are historical antecedents of the current anti-Asian racism that has become even more pronounced as a result of COVID-19. Social studies educators can leverage these court cases to teach about controversial and relevant issues that connect to current immigration and citizenship policies, as well as provide historical context for contemporary discussions about race and racism.
