In the premiere episode of "The Sentinel," the National Congress of American Indians (NCAI) invites you along on a journey through time, exploring the pivotal moments that have shaped the exercise of tribal sovereignty. First, travel back to NCAI's inception in 1944 and witness the ever-evolving needs of Tribal Nations in the face of mounting threats to tribal self-determination. Next, join us as we delve into the historical significance of the first NCAI Mid Year Conference held in Albuquerque, New Mexico, in 1977. Hear firsthand from tribal leaders as they shed light on the profound importance of that first Mid Year convening, where Tribal Nations united to combat anti-Indian rhetoric and protect tribal sovereignty. Then, fast forward 46 years to the 2023 Mid Year Convention & Marketplace as NCAI assembles Tribal Nations on the homelands of the Shakopee Mdewakanton Sioux Community in Minnesota, to address pressing issues surrounding environmental sustainability and climate resilience.  Stay tuned as the episode closes with a powerful tribute to the life and legacy of Head Councilman Joe Garcia (Ohkay Owingeh), a former two-time NCAI President and champion of Indian Country.
