<P> The Five "Civilized" Tribes were indigenous peoples of the Americas who lived in the Southeastern United States . Most were descendants of what is now called the Mississippian culture, an agrarian culture that grew crops of corn and beans, with hereditary religious and political elites . The Mississippian Culture flourished in what is now the Midwestern, Eastern, and Southeastern United States from 800 to 1500 . Before European contact these tribes were generally matrilineal societies . Agriculture was the primary economic pursuit . The bulk of the tribes lived in towns (some covering hundreds of acres and populated with thousands of people). These communities regulated their space with planned streets, subdivided into residential and public areas . Their system of government was hereditary . Chiefdoms were of varying size and complexity, with high levels of military organization . </P> <P> George Washington and Henry Knox pursued an agenda of cultural transformation in relation to Native Americans . The Cherokee and Choctaw tended, in turn, to adopt and appropriate certain cultural aspects of the federation of colonies . At the time of the Declaration of Independence, the culture of the United States as a nation was, itself, emergent . Many of the cultural practices appropriated by The Five Tribes were ones that they found useful . </P> <P> In the early part of the 19th century, the U.S. government initiated a displacement of the existing societies living east of the Mississippi River, including The Five Tribes, to lands west of the river . This displacement initiative was dubbed the Indian Removal . The Indian Removal forced a significant number of the Five Tribes to Indian Territory in other parts of the North American continent . A significant number were displaced to the area that would, in future, become the state of Oklahoma . At the time of their removal, the tribes were suzerain nations . </P> <P> The federally legislated displacement of the tribes from their homes east of the Mississippi River took place over several decades during the series of removals, which is also known as the Trail of Tears . The territory to which they were displaced was, at the time, called Indian Territory, currently eastern Oklahoma . The most infamous removal was the Cherokee Trail of Tears of 1838, when President Martin Van Buren enforced the contentious Treaty of New Echota with the Cherokee Nation . One point of contention regarding the treaty is whether it is an instrument of mass displacement in violation of the human rights on which the new republic had been established, or a legal exchange of territory for land further west . </P>
