During the 1960s and early 1970s, dozens of groups that lacked federal acknowledgment came forward to demand their rights as Native peoples. In the east, groups like the Mashpee Wampanoag filed suit for lands lost in preceding generations. In the west, groups sought fishing rights. In the southeast, others came to demand the government recognize them as surviving aboriginal peoples. As federal tribal status allowed groups standing to bring claims and many came to see the injustice of denying acknowledgment to indigenous peoples, many parties came to acknowledge the need for more consistent procedures for recognizing tribes left outside the circle. With tribal input, the BIA created its Federal Acknowledgment Process in 1978. Currently known as the Office of Federal Acknowledgment, this entity is the main body charged with deciding which groups are eligible to secure status.
