President Andrew Jackson forced Natives to leave their lands. He passed the  Indian Removal Act of 1830. This led to the Trail of Tears. Americans justified this removal. This was called Manifest Destiny. In 1851, the Indian Appropriations Act set up preservations for Natives. Natives resisted in the Indian Wars. There was also the Dakota War, Great Sioux War, Snake War, Colorado War, and Texas-Indian Wars. In the Wounded Knee Massacre, the US army killed many Natives.
