The Indian Claims Commission (ICC) was a judicial relations arbiter between the United States federal government and Native American tribes. It was established under the Indian Claims Act of 1946 by the United States Congress to hear any longstanding claims of Indigenous tribes against the United States. The Commission created a process for tribes to address their grievances against the United States, and offered monetary compensation for territory lost as a result of broken federal treaties. Its purpose was to serve as a tribunal for hearing claims against the United States arising prior to that date by any Native American tribe or other identifiable group of Indigenous people living in the United States.
