# Yankton Treaty

The Yankton Treaty was a treaty signed in 1858 between the United States Government and the Yankton Sioux Tribe (Western Dakota), that ceded most of eastern South Dakota (11 million acres) to the U.S. Government. The treaty was signed in April 1858, and ratified by the United States Congress on February 16, 1859.

## Background

The 1851 Treaty of Traverse des Sioux, which ceded vast tracts of Sioux land to the U.S. government, was signed only by representatives of the Sisseton and Mdewakanton bands. The Yankton and Yanktonai tribes were not consulted. Governor Ramsey used the Nicollet map of the Upper Mississippi River basin from 1840 to draw the boundaries. He saw the Big Sioux River as a geographic feature separating the Sisseton and Yankton and Yanktonai tribes. Chief Waanata 1 of the Yanktonai claimed from Granite Falls to the Missouri River. Chief Struck-by-the-Ree of the Yankton claimed the land into Minnesota to the Jeffers Petroglyphs. The Yankton made their objections known. The Government realized the Yankton claim was so strong that the Yankton treaty was drawn up. As the Government felt it did not have free and clear title to the land for the statehood of Minnesota. Paragraph 1 of the 1858 Yankton treaty addresses these claims immediately. However, Struck-by-the-Ree would not sign without a provision for the Pipestone quarry. Article 8 was added giving the Yankton a one mile square Reservation at Pipestone. Struck-by-the-Ree signed and one month later Minnesota gained statehood. The Yanktonai being more remote failed to have their objections considered. The 1858 treaty immediately opened this territory up for settlement, resulting in the establishment of an unofficial local government not recognized by Washington. The treaty also created the primary 430,000 acre Yankton Sioux Reservation, now located in Charles Mix County in South Dakota.

## Negotiations

Smutty Bear (Ma-to-sa-be-che-a), a Yankton chief, was opposed the treaty because he felt it would only bring further white intrusions as they pushed to settle the open prairie with no obvious impediments. Strike-the-Ree (Pa-le-ne-a-pa-pe, also known as "The Man that Struck the Ree"), the elder Yankton Sioux chief, also felt that too many whites were settling there, but decided that opposing them was futile, and he signed the treaty. Charles F. Picotte, speculator, entrepreneur, and translator was compensated with a 640-acre land grant in the newly incorporated territory. That parcel later became a major portion of the city of Yankton, South Dakota.

## Terms

The terms of the treaty can be summarized as follows:
