"The Globalization of Indigenous Women's Movements and The United Nations System (1992-2012)" is a comprehensive study of the globalization of indigenous women's movements that materialized in the early 1990s. These movements flourished parallel to other transnational social movements, such as International Zapatismo, the World Social Forum, and Gender as Human Rights Movement, yet they are omitted and remain invisible within transnational and global social movement literature. This study is an inscription of these processes, through the construct of a textual space that exposes a global decolonial feminist imaginary grounded in the oral histories of thirty-one international indigenous women leaders. The primary site for this study is the United Nations Permanent Forum on Indigenous Issues (UNPFII), a venue where contact amongst indigenous women worldwide occurs annually at the United Nations (UN) Headquarters in New York City. This qualitative study uses decolonial and feminist methodology to examine in-depth semi-structured interviews, transcriptions of key speeches, plenaries and interventions made by indigenous women at the United Nations Permanent Forum on Indigenous Issues and other relevant international forums, and field notes compiled from my full-participant and participant-observation in international forums. My dissertation makes two claims. First, I argue that indigenous women have made formal gains within the UN System via an unprecedented process of simultaneously accepting, contesting and altering the structural opportunities and constraints present within the UN. These processes made it possible for UNPFII's actors and their key claims to be effectively integrated within the multiple agencies that make up the UN. I identify key Indigenous actors and trace their claims for social justice, which have transcended the domestic sphere to the global political arena. Second, I argue that, globalization has reconfigured transnational political spaces for indigenous women activists and that these UN advocates frame their claims for rights in a unique way, in a process that combines individual human rights as well as collective indigenous peoples rights.
