The Boldt Decision refers to a landmark federal court ruling made in 1974 that affirmed the treaty rights of Native American tribes in Washington State to fish in their traditional waters. This ruling emphasized that tribes have the right to harvest fish at levels sufficient to meet their cultural and subsistence needs, and it mandated that the state of Washington share the fishing resources with these tribes. This decision played a crucial role in the Red Power movement by validating tribal sovereignty and igniting broader activism among Native American communities.
