Step-by-step explanation:
The Trail of Tears refers to the forced removal of Native American tribes from the southeastern United States to Indian Territory, under the Indian Removal Act of 1830. This event primarily involved the Cherokee tribe and is a significant part of American history, depicting the struggles and suffering endured by Native Americans due to U.S. governmental policies.
