To what degree are nations "rewriting" citizenship by expanding discussions of human rights, diversity and cultural pluralism in modern civic education, and what explains variation between countries? This study addresses these issues by analysing the intended content of civic education in Costa Rica and Argentina. Over time, civic education in both countries has become more focused on rights and the empowerment of individuals. In addition, both countries embrace aspects of global citizenship through an affirmation of human rights. Citizenship thus expands outward and upward, incorporating more groups and people into the national polity while also broadening the concept of citizenship beyond the nation-state. Nevertheless, Costa Rica and Argentina vary in the intensity of the adoption of global citizenship, most likely a result of divergent historical experiences with state sponsored violence.
