 The Modoc and Klamath tribes were terminated under the Indian termination policy from federal supervision by the Klamath Termination Act, or Public Law 587, enacted on August 13, 1954.At Congressional hearings during 1965, testimony showed the Modoc living in Oklahoma, Kansas, and Missouri had not been properly notified that their tribe would be terminated simultaneously with the Klamath Reservation, as none of the public notices identified that the termination included the Modoc.Several years later all tribes in the northeastern corner of Oklahoma banded together to establish the Inter-Tribal Council, Inc. of Northeastern Oklahoma.
