Document 2: Indian removal: Indian removal was a policy of the United States government in the 19th century whereby Native Americans were forcibly removed from their ancestral homelands in the eastern United States to lands west of the Mississippi River, thereafter known as Indian Territory. In a matter that remains one of debate by scholars, description of the policy—which clearly contributed to devastation in numbers, freedom and prosperity for those displaced—is sometimes elevated to being one of long-term genocide of Native Americans, in any case, a consequence of actions first by European settlers to North America in the colonial period, then by the United States government and its citizens until the mid-20th century. The policy traced its direct origins to the administration of James Monroe, though it addressed conflicts between European Americans and Native Americans that had been occurring since the 17th century, and were escalating into the early 19th century as white settlers were continually pushing westward. The Indian Removal Act was the key law that forced the removal of the Indians, and was signed into law by President Andrew Jackson on May 28, 1830.
Document 3: Cherokee Nation: The Cherokee Nation (Cherokee: ᏣᎳᎩᎯ ᎠᏰᎵ, "Tsalagihi Ayeli"), also known as the Cherokee Nation of Oklahoma, is the largest of three Cherokee federally recognized tribes in the United States. It was established in the 20th century and includes people descended from members of the Old Cherokee Nation who relocated from the Southeast due to increasing pressure to Indian Territory and Cherokee who were forced to relocate on the Trail of Tears. The tribe also includes descendants of Cherokee Freedmen and Natchez Nation. Over 299,862 people are enrolled in the Cherokee Nation, with 189,228 living within the state of Oklahoma. According to Bureau of Indian Affairs (BIA) head Larry EchoHawk, the Cherokee Nation is not the historical Cherokee tribe but instead a "successor in interest."
Document 4: Choctaw Trail of Tears: The Choctaw Trail of Tears was the relocation of the Choctaw Nation from their country referred to now as the Deep South (Alabama, Arkansas, Mississippi, and Louisiana) to lands west of the Mississippi River in Indian Territory in the 1830s. A Choctaw miko (chief) was quoted by the Arkansas Gazette that the removal was a "trail of tears and death." After removal the Choctaws became three distinct groups, the Choctaw Nation of Oklahoma, Jena Band of Choctaw Indians, and the Mississippi Band of Choctaw Indians.
Document 5: Cherokee removal: Cherokee removal, part of the Trail of Tears, refers to the forced relocation between 1836 and 1839 of the Cherokee Nation from their lands in Georgia, South Carolina, North Carolina, Tennessee, Texas, and Alabama to the Indian Territory (present day Oklahoma) in the then Western United States, and the resultant deaths along the way and at the end of the movement of an estimated 4000 Cherokee.
Document 6: Chieftains Museum (Major Ridge Home): Chieftains Museum, also known as the Major Ridge Home, is a two-story white frame house built around a log house of 1792 in Cherokee country (today it is within present-day Rome, Georgia). It was the home of the Cherokee leader Major Ridge— notable for his role in negotiating and signing the Treaty of New Echota of 1835, which ceded the remainder of Cherokee lands in the Southeast to the United States. He was part of a minority group known as the Treaty Party, who believed that relocation was inevitable and wanted to negotiate the best deal with the United States for their people. The chiefs had agreed they could not go to war against the United States on the removal issue, but most other Cherokee opposed Ridge and the Treaty Party. He and some other members of the Treaty Party were murdered after removal to the Cherokee Nation in Indian Territory for having ceded the tribe's communal lands, as this was considered a capital crime.
Document 7: The Way to Rainy Mountain: The Way to Rainy Mountain (1969) is a book by Pulitzer Prize winning author N. Scott Momaday. It is about the journey of Momaday's Kiowa ancestors from their ancient beginnings in the Montana area to their final war and surrender to the United States Cavalry at Fort Sill, and subsequent resettlement near Rainy Mountain, Oklahoma.
Document 8: Dee Brown (writer): Dorris Alexander "Dee" Brown (February 29, 1908 – December 12, 2002) was an American novelist, historian, and librarian. His most famous work, "Bury My Heart at Wounded Knee" (1970) details the history of American expansionism from the point of view of the Native Americans.
Document 9: Indian Removal Act: The Indian Removal Act was signed by President Andrew Jackson on May 28, 1830. The law authorized the president to negotiate with southern Indian tribes for their removal to federal territory west of the Mississippi River in exchange for their lands. The act enjoyed strong support from the non-Indian peoples of the South, but there was a large amount of resistance from the Indian tribes. Cherokee tribes came together as an independent nation to stop this relocation, but they were unsuccessful.
Document 10: Trail of Tears (disambiguation): Trail of Tears was a series of forced relocations of Native American nations from their ancestral homelands in the Southeastern United States following the passage of the Indian Removal Act of 1830.
Document 11: Bury My Heart at Wounded Knee: Bury My Heart at Wounded Knee: An Indian History of the American West is a 1970 book by American writer Dee Brown that covers the history of Native Americans in the American West in the late nineteenth century. The book expresses details of the history of American expansionism from a point of view that is critical of its effects on the Native Americans. Brown describes Native Americans' displacement through forced relocations and years of warfare waged by the United States federal government. The government's dealings are portrayed as a continuing effort to destroy the culture, religion, and way of life of Native American peoples. Helen Hunt Jackson's "A Century of Dishonor" is often considered a nineteenth-century precursor to Dee Brown's writing.
Document 12: Indian removals in Indiana: Indian removals in Indiana followed a series of the land cession treaties made between 1785 and 1846 that led to the removal of most of the native tribes from Indiana. Some of the removals occurred prior to 1830, but most took place between 1830 and 1846. The Lenape (Delaware), Piankashaw, Kickapoo, Wea, and Shawnee were removed in the 1820s and 1830s, but the Potawatomi and Miami removals in the 1830s and 1840s were more gradual and incomplete, and not all of Indiana’s Native Americans voluntarily left the state. The most well-known resistance effort in Indiana was the forced removal of Chief Menominee and his Yellow River band of Potawatomi in what became known as the Potawatomi Trail of Death in 1838, in which 859 Potawatomi removed to Kansas and at least forty died on the journey west. The Miami were the last to remove from Indiana, but tribal leaders delayed the process until 1846. Many of the Miami were permitted to remain on land allotments guaranteed to them under the Treaty of St. Mary's (1818) and subsequent treaties.

Document 14: Trail of Tears: The Trail of Tears was a series of forced removals of Native American nations from their ancestral homelands in the Southeastern United States to an area west of the Mississippi River that had been designated as Indian Territory. The forced relocations were carried out by various government authorities following the passage of the Indian Removal Act in 1830. The relocated people suffered from exposure, disease, and starvation while en route, and more than four thousand died before reaching their various destinations. The removal included members of the Cherokee, Muscogee (Creek), Seminole, Chickasaw, and Choctaw nations. The phrase "Trail of Tears" originated from a description of the removal of the Cherokee Nation in 1838.
