Step-by-step explanation:
The Indian Removal Act of 1830 was an example of manifest destiny because it was a policy that reflected the belief in the expansion of the United States from coast to coast. The act forced the relocation of Native American tribes from their ancestral lands to areas west of the Mississippi River. This expansionist policy was driven by the idea that it was the destiny of the United States to occupy and control the entire North American continent.
