The Indian removal was the United States government policy of ethnic cleansing through forced displacement of self-governing tribes of American Indians from their ancestral homelands in the eastern United States to lands west of the Mississippi River—specifically, to a designated Indian Territory (roughly, present-day Oklahoma), which many scholars have labeled a genocide.
The Indian Removal Act of 1830, the key law which authorized the removal of Native tribes, was signed into law by United States president Andrew Jackson on May 28, 1830.
