Indian Territory and the Indian Territories are terms that generally described an evolving land area set aside by the United States government for the relocation of Native Americans who held original Indian title to their land as an independent nation. The concept of an Indian territory was an outcome of the U.S. federal government's 18th- and 19th-century policy of Indian removal. After the American Civil War (1861–1865), the policy of the U.S. government was one of assimilation.

Indian Territory later came to refer to an unorganized territory whose general borders were initially set by the Nonintercourse Act of 1834, and was the successor to the remainder of the Missouri Territory after Missouri received statehood. The borders of Indian Territory were reduced in size as various Organic Acts were passed by Congress to create organized territories of the United States. The 1906 Oklahoma Enabling Act created the single state of Oklahoma by combining Oklahoma Territory and Indian Territory, ending the existence of an unorganized independent Indian Territory as such, and formally incorporating the tribes and residents into the United States.

Before Oklahoma statehood, Indian Territory from 1890 onward comprised the territorial holdings of the Cherokee, Choctaw, Chickasaw, Creek, Seminole, and other displaced Eastern American tribes. Indian reservations remain within the boundaries of U.S. states, but are largely exempt from state jurisdiction. The term "Indian country" today is used to signify lands under the control of Native nations, including Indian reservations, trust lands on Oklahoma Tribal Statistical Area, or, more casually, to describe anywhere large numbers of Native Americans live.

Description and geography

Indian Territory, also known as the Indian Territories and the Indian Country, was land in the United States reserved for the forced resettlement of Native Americans. As such, it was not a traditional territory for the tribes settled upon it.Everett, Dianna. "Indian Territory ," Encyclopedia of Oklahoma History and Culture, published by the Oklahoma Historical Society (accessed October 17, 2013). The general borders were set by the Indian Intercourse Act of 1834. The territory was located in the Central United States.

While Congress passed several Organic Acts that provided a path for statehood for much of the original Indian Country, Congress never passed an Organic Act for the Indian Territory. Indian Territory was never an organized territory of the United States. In general, tribes could not sell land to non-Indians (Johnson v. McIntosh). Treaties with the tribes restricted entry of non-Indians into tribal areas; Indian tribes were largely self-governing, were suzerain nations, with established tribal governments and well established cultures. The region never had a formal government until after the American Civil War.

After the Civil War, the Southern Treaty Commission re-wrote treaties with tribes that sided with the Confederacy, reducing the territory of the Five Civilized Tribes and providing land to resettle Plains Indians and tribes of the Midwestern United States.Pennington, William D. Encyclopedia of Oklahoma History and Culture. "Reconstruction Treaties." Retrieved February 16, 2012. These re-written treaties included provisions for a territorial legislature with proportional representation from various tribes.

In time, the Indian Territory was reduced to what is now Oklahoma. The Organic Act of 1890 reduced Indian Territory to the lands occupied by the Five Civilized Tribes and the Tribes of the Quapaw Indian Agency (at the borders of Kansas and Missouri). The remaining western portion of the former Indian Territory became the Oklahoma Territory.

The Oklahoma Organic Act applied the laws of Nebraska to the organized Oklahoma Territory, and the laws of Arkansas to the still unorganized Indian Territory, since for years the federal U.S. District Court on the eastern borderline in Ft. Smith, Arkansas had criminal and civil jurisdiction over the territory.

History Indian Reserve and the Louisiana Purchase

The concept of an Indian territory is the successor to the British Indian Reserve, a British American territory established by the Royal Proclamation of 1763 that set aside land for use by the Native American tribes. The proclamation limited the settlement of Europeans to lands east of the Appalachian Mountains. The territory remained active until the Treaty of Paris that ended the American Revolutionary War, and the land was ceded to the United States. The Indian Reserve was slowly reduced in size via treaties with the American colonists, and after the British defeat in the Revolutionary War, the Reserve was ignored by European American settlers who slowly expanded westward.

At the time of the American Revolutionary War, many Native American tribes had long-standing relationships with the British, and were loyal to Great Britain, but they had a less-developed relationship with the American colonists. After the defeat of the British in the war, the Americans twice invaded the Ohio Country and were twice defeated. They finally defeated the Indian Western Confederacy at the Battle of Fallen Timbers in 1794, and imposed the Treaty of Greenville, which ceded most of what is now Ohio, part of present-day Indiana, and the lands that include present-day Chicago and Detroit, to the United States federal government.

The period after the American Revolutionary War was one of rapid western expansion. The areas occupied by Native Americans in the United States were called Indian country. They were distinguished from "unorganized territory" because the areas were established by treaty.

In 1803, the United States agreed to purchase France's claim to French Louisiana for a total of $15 million (less than 3 cents per acre).

President Thomas Jefferson doubted the legality of the purchase. Robert R. Livingston, the chief negotiator of the purchase, however, believed that the 3rd article of the treaty of the Louisiana Purchase would be acceptable to Congress. The 3rd article stated, in part:

This committed the U.S. government to "the ultimate, but not to the immediate, admission" of the territory as multiple states, and "postponed its incorporation into the Union to the pleasure of Congress".

After the Louisiana Purchase in 1803, President Thomas Jefferson and his successors viewed much of the land west of the Mississippi River as a place to resettle the Native Americans, so that white settlers would be free to live in the lands east of the river. Indian removal became the official policy of the United States government with the passage of the 1830 Indian Removal Act, formulated by President Andrew Jackson.

When Louisiana became a state in 1812, the remaining territory was renamed Missouri Territory to avoid confusion. Arkansaw Territory, which included the present State of Arkansas plus much of the state of Oklahoma, was created out of the southern part of Missouri Territory in 1819. During negotiations with the Choctaw in 1820 for the Treaty of Doak's Stand, Andrew Jackson ceded more of Arkansas Territory to the Choctaw than he realized, from what is now Oklahoma into Arkansas, east of Ft. Smith, Arkansas. The General Survey Act of 1824 allowed a survey that established the western border of Arkansas Territory 45 miles west of Ft. Smith. But this was part of the negotiated lands of Lovely's Purchase where the Cherokee, Choctaw, Creek and other tribes had been settling, and these Indian nations objected strongly. In 1828 a new survey redefined the western Arkansas border just west of Ft. Smith. After these redefinitions, the "Indian zone" would cover the present states of Oklahoma, Kansas, Nebraska and part of Iowa.

Relocation and treaties

Before the 1871 Indian Appropriations Act, much of what was called Indian Territory was a large area in the central part of the United States whose boundaries were set by treaties between the US Government and various indigenous tribes. After 1871, the Federal Government dealt with Indian Tribes through statute; the 1871 Indian Appropriations Act also stated that "hereafter no Indian nation or tribe within the territory of the United States shall be acknowledged or recognized as an independent nation, tribe, or power with whom the United States may contract by treaty: Provided, further, That nothing herein contained shall be construed to invalidate or impair the obligation of any treaty heretofore lawfully made and ratified with any such Indian nation or tribe".25 U.S.C. § 71. Indian Appropriation Act of March 3, 1871, 16 Stat. 544, 566Congress' plenary authority to "override treaty provisions and legislate for the protection of the Native Americans." United States v. City of McAlester, 604 F.2d 42, 47 (10th Cir. 1979)United States v. Blackfeet Tribe of Blackfeet Indian Reservation, 364 F.Supp. 192, 194 (D.Mont. 1973) ("[A]n Indian tribe is sovereign to the extent that the United States permits it to be sovereign – neither more nor less.")

The Indian Appropriations Act also made it a federal crime to commit murder, manslaughter, rape, assault with intent to kill, arson, burglary, or larceny within any Territory of the United States. The Supreme Court affirmed the action in 1886 in United States v. Kagama, which affirmed that the U.S. government has plenary power over Native American tribes within its borders using the rationalization that "The power of the general government over these remnants of a race once powerful ... is necessary to their protection as well as to the safety of those among whom they dwell". While the federal government of the United States had previously recognized the Indian Tribes as semi-independent, "it has the right and authority, instead of controlling them by treaties, to govern them by acts of Congress, they being within the geographical limit of the United States ... The Indians [Native Americans] owe no allegiance to a State within which their reservation may be established, and the State gives them no protection."

Reductions of area

White settlers continued to flood into Indian country. As the population increased, the homesteaders could petition Congress for creation of a territory. This would initiate an Organic Act, which established a three-part territorial government. The governor and judiciary were appointed by the President of the United States, while the legislature was elected by citizens residing in the territory. One non-voting representative was allowed a seat in the U.S. House of Representatives. The federal government took responsibility for territorial affairs. Later, the inhabitants of the territory could apply for admission as a full state. No such action was taken for the so-called Indian Territory, so that area was not treated as a legal territory.

The reduction of the land area of Indian Territory (or Indian Country, as defined in the Indian Intercourse Act of 1834), the successor of Missouri Territory began almost immediately after its creation with: Wisconsin Territory formed in 1836 from lands east of the Mississippi and between the Mississippi and Missouri rivers. Wisconsin became a state in 1848 Iowa Territory (land between the Mississippi and Missouri Rivers) was split from Wisconsin Territory in 1838 and became a state in 1846. Minnesota Territory was split from Iowa Territory in 1849 and part of the Minnesota Territory became the state of Minnesota in 1858 Dakota Territory was organized in 1861 from the northern part of Indian Country and Minnesota Territory. The name refers to the Dakota branch of the Sioux tribes. North Dakota and South Dakota became separate states simultaneously in 1889. Present-day states of Montana and Wyoming were also part of the original Dakota Territory
