Abstract
What role does the international system play in amplifying the impact of domestic social movements on social change? The Argentine human rights movement reached the international system through the projection of cognitive and affective information—persuasion. International response was facilitated by the international human rights regime, and transnational nongovernmental organizations (NGOs) played a critical role. This challenge from above and below did have a clear impact on the target government and the development of broader mechanisms for the protection of human rights—even under the most severe conditions of repression and powerlessness.
