Does the United States still make treaties with Indian tribes?
No. Congress ended treaty-making with Indian tribes in 1871. Since then, relations with Indian groups have been formalized and/or codified by Congressional acts, Executive Orders, and Executive Agreements. Between 1778, when the first treaty was made with the Delawares, to 1871, when Congress ended the treaty-making period, the United States Senate ratified 370 treaties. At least 45 others were negotiated with tribes but were never ratified by the Senate. The treaties that were made often contain commitments that have either been fulfilled or subsequently superseded by Congressional legislation.
