By the later half of the nineteenth century native American Indians were pushed off to the Great American Desert. Americans wanted to reach manifest destiny and hence moved westward which made the native Americans to forcefully move out of their lands and paved way for American Indian wars.
Step-by-step explanation:
The western lands belonged to the Indians and they felt they were being forcefully displaced from their lands. Americans also wanted to constructed railroads across the country and unfortunately these weer on the lands occupied by the native Americans.
The Trail of Tears was when the United States government forced Native Americans to move from their homelands in the Southern United States to Indian Territory in Oklahoma. Peoples from the Cherokee, Muscogee, Chickasaw, Choctaw, and Seminole tribes were marched at gunpoint across hundreds of miles to reservation lands.
The Indian Removal Act was passed by Congress in 1830. The actual removal of the Native American tribes from the South took several years. It began with the removal of the Choctaw in 1831 and ended with the removal of the Cherokee in 1838.
