These essays take a much-needed look at the course of human rights strategies rooted in the last century's struggles against brutally repressive dictators. Those struggles continue today across Latin America. Augmented by the pursuit of broader political, cultural, labor, and environmental rights, they hold accountable a much wider cast of national governments, local governments, international agencies, and multinational corporations. In "Sustaining Human Rights in the Twenty-first Century", some of the Western Hemisphere's leading human rights experts shape and bolster new approaches, from the concepts of rights to transnational efforts, by placing the struggle for rights in historical and comparative perspective. The contributors provide an historical framework, describe formal and legal institutions, and discuss the citizens' movements and conceptions of citizenship that produce distinct kinds of political identities and struggles.
