Who was the manifest destiny talking about?

Manifest Destiny was a 19th-century doctrine that justified the expansion of the United States across North America. It primarily referred to the belief that American settlers were destined to expand their territory from the Atlantic to the Pacific Oceans. This ideology was often used to rationalize the displacement of Native American tribes and the annexation of territories such as Texas and California. Ultimately, it reflected a sense of American exceptionalism and a belief in the country’s divine right to expand.
