Cherokee removal, part of the Trail of Tears, refers to the forced relocation between 1836 and 1839 of an estimated 16,000 members of the Cherokee Nation and 1,000–2,000 of their slaves; from their lands in Georgia, South Carolina, North Carolina, Tennessee, 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 4,000 Cherokee and unknown number of slaves, although no records of these deaths have ever materialized. Many scholars believe these Indians absconded from the removal rather than died. The Cherokee have come to call the event Nu na da ul tsun yi (the place where they cried); another term is Tlo va sa (our removal)—both phrases not used at the time, and seems to be of Choctaw origin. Removal actions (voluntary, reluctantly or forcibly) occurred to other American Indian groups in the American South, North, Midwest, Southwest, and the Plains regions. The Chickasaw, Choctaw, Muskogee (Creek), and Cherokee were removed reluctantly. The Seminole in Florida resisted removal by the United States Army for decades (1817–1850) with guerrilla warfare, part of the intermittent Native American Wars that lasted from 1540 to 1924. Some Seminole remained in their Florida home country, while others were transported to Native American Territory in shackles. The phrase "Trail of Tears" is used to refer to similar events endured by other Indian groups, especially among the "Five Civilized Tribes". The phrase originated as a description of the involuntary removal of the Choctaw Nation in 1831. In the fall of 1835, a census was taken by civilian officials of the US War Department to enumerate Cherokee residing in Alabama, Georgia, North/South Carolina, and Tennessee, with a count of 16,542 Cherokee, 201 inter-married whites, and 1592 slaves (total: 18,335 people). Tensions between the indigenous Cherokee and white settlers developed over ownership of the land rich in gold deposits and fertile soil that could be used for farming cotton.
