Information: - As general terms, Indian Territory, the Indian Territories, or Indian country describe an evolving land area set aside by the United States Government for the relocation of Native Americans who held aboriginal title to their land. In general, the tribes ceded land they occupied in exchange for land grants in an area purchased by the United States federal government from Napoleonic France, the Louisiana Purchase. The concept of an Indian Territory was an outcome of the 18th- and 19th-century policy of Indian removal. After the Civil War, the policy of the government was one of assimilation. - The Louisiana Purchase ("Sale of Louisiana") was the acquisition of the Louisiana territory (828,000 square miles = 2.14 million km) by the United States from France in 1803. The U.S. paid fifty million francs ($11,250,000 USD) and a cancellation of debts worth eighteen million francs ($3,750,000 USD) for a total of sixty-eight million francs ($15,000,000 USD, or around a quarter of a billion in 2016 dollars). The Louisiana territory included land from fifteen present U.S. states and two Canadian provinces. The territory contained land that forms Arkansas, Missouri, Iowa, Oklahoma, Kansas, and Nebraska; the portion of Minnesota west of the Mississippi River; a large portion of North Dakota; a large portion of South Dakota; the northeastern section of New Mexico; the northern portion of Texas; the area of Montana, Wyoming, and Colorado east of the Continental Divide; Louisiana west of the Mississippi River (plus New Orleans); and small portions of land within the present Canadian provinces of Alberta and Saskatchewan. Its population was around 60,000 inhabitants, of whom half were African slaves. - Oklahoma (Cherokee: "Asgaya gigageyi" / ; or transliterated from English as ("oalahoma"), Pawnee: "Uukuhuuwa", Cayuga: "Gahnawiyogeh") is a state located in the South Central United States. Oklahoma is the 20th-most extensive and the 28th-most populous of the 50 United States. The state's name is derived from the Choctaw words "okla" and "humma", meaning "red people". It is also known informally by its nickname, "The Sooner State", in reference to the non-Native settlers who staked their claims on the choicest pieces of land before the official opening date, and the Indian Appropriations Act of 1889, which opened the door for white settlement in America's Indian Territory. The name was settled upon statehood, Oklahoma Territory and Indian Territory were merged and Indian was dropped from the name. On November 16, 1907, Oklahoma became the 46th state to enter the union. Its residents are known as "Oklahomans", or informally "Okies", and its capital and largest city is Oklahoma City. - Fort Gibson is now located adjacent to the present day city of "Fort Gibson," in Muskogee County Oklahoma. It is designated the Fort Gibson Historical Site. It guarded the American frontier in Indian Territory from 1824 until 1888. When constructed, the fort lay farther west than any other military post in the United States; it formed part of the northsouth chain of forts intended to maintain peace on the frontier of the American West and to protect the southwestern border of the Louisiana Purchase. The fort succeeded in its peacekeeping mission for more than 50 years, as no massacres or battles occurred there. - Commandant 's Quarters of Fort Gibson was built in 1868 . The building was listed on the National Register of Historic Places in 1985 . The larger Fort Gibson , which may include this building , was declared a National Historic Landmark in 1960 .
