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.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, Creek and (Muskogee) were removed reluctantly. The Seminole in Florida resorted to removal by the United States Army for decades (1817–1850) with guerrilla warfare. Some Seminole remained in their Florida home country, while others were transported to Indian 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 voluntary removal of the Choctaw nation in 1831.
