Historically, the tribe were the protectors of the sacred Pipestone Quarry for the Oceti Sakowin.

The tribe maintains a free-ranging bison herd.[5]

Lewis & ClarkEdit

According to local legend, when Meriwether Lewis learned that a male child had been born near the expedition's encampment in what is today southeastern South Dakota, he sent for the child and wrapped the new born baby boy in an American flag during the council at Calumet Bluff in late August 1804. Lewis declared the baby an American. This boy grew up to become a headman (chief) of the Ihanktonwan Dakota (Yankton Sioux), known as Struck By-the-Ree. However, the journals of the expedition make no mention of this incident.

Pressure and land cessionEdit

By the late 1850s, pressure to open up what is now southeastern South Dakota to white settlement had become very strong. Struck-by-the-Ree and several other headmen journeyed to Washington, D.C., in late 1857 to negotiate a treaty with the federal government. For more than three and a half months, they worked out the terms of a treaty of land cession. The Treaty of Washington was signed April 19, 1858.

Returning from Washington, Padaniapapi (Struck-by-The-Ree) told his people, "The white men are coming in like maggots. It is useless to resist them. They are many more than we are. We could not hope to stop them. Many of our brave warriors would be killed, our women and children left in sorrow, and still we would not stop them. We must accept it, get the best terms we can get and try to adopt their ways."

For about eleven and a half million acres, a payment of approximately $1.6 million in annuities was to paid over the next 50 years. Specific provisions of the treaty called for educating the tribe to develop skills in agriculture, industrial arts and homemaking. This treaty provided for the removal of the tribe to a 475,000-acre reservation on the north side of the Missouri River in what is now Charles Mix County. (Charles E. Mix was the commissioner who signed for the federal government.) The US Senate ratified the treaty on February 16, 1859 and President James Buchanan authorized it ten days later. On July 10, 1859, the Yankton Sioux vacated the ceded lands and moved onto the newly created reservation.


The tribe's headquarters are in Wagner, South Dakota[5] and it is governed by a democratically elected non-IRA tribal council. Its original constitution was ratified in 1891.[6]

It is the only Dakota/Lakota tribe in South Dakota without that did not agree to comply with the Indian Reorganization Act and retains its traditional government.

Officially, the Yankton Sioux Tribe is called "Ihanktonowan Dakota Oyate" in the local dialect. The Yankton Sioux, or Dakota people, adopted a unique tribal symbol on September, 24, 1975. With minor alterations this symbol serves as seal, logo and flag.

Crossing the yellow portions of the flag approximately one-third from the bottom is an undulating red line. This symbolizes a "prayer" to bind the home in love and safety. Red was chosen by designer Gladys L. Moore, a Yankton Sioux from Union Lake (Ibid), Michigan, because it is a symbol of life. The color red was painted around the lower parts of tepees to indicate that those that visited would be fed or that that particular tepee was one of several in which a feast was to be held.


The tribe's reservation is the Yankton Indian Reservation, established in 1853 in Charles Mix County, South Dakota. The tribe has a land base of 36,741 acres.[7] Most of the tribe moved onto the reservation in the 1860s.[8]

Economic developmentEdit

The tribe owns and operates the Fort Randall Casino and Hotel in Pickstown, South Dakota, and Lucky Lounge and Four Directions Restaurant.[9]

Other major employers include Indian Health Services, the tribe itself, Bureau of Indian Affairs, and Marty Indian School.[5]
