Institute for Transborder Indigenous Nations (ITIN)

What is ITIN?

ITIN is a community of scholars, public intellectuals, and Indigenous community members working on behalf of the interests of Indigenous peoples impacted by the US-Mexico Border. As such, we represent one of many regions around the world in which Indigenous nations intersect with non-Indigenous settler-colonial nation states. Each region is home to a diversity of languages, cultures, histories, nations and bioregions. In the case of the US-Mexico Transborder region, which stretches for nearly two thousand miles, from the Pacific Ocean to the Gulf of Mexico, there are twenty-nine Indigenous communities along the international divide. As an institute housed in ASU’s School of Transborder Studies, our primary focus is the Arizona-Sonora border.
