Manifest destiny was a widely held belief, in 19th century United States, that its settlers were destined to expand all across North America. This mission was believed to be divine, good, and a way to spread democracy, freedom and American culture. Manifest destiny had 3 main themes: the virtue of the American people and their institutions, the mission to spread these institutions in order to remake the world in the image of the United States, and the destiny under god to complete this work. In the 1840s, this phrase was used by Jackson Democrats to promote annexation of what is today most of Western United States. The group that had the most reason to be concerned about manifest destinty, were the Native Americans. This is because the principle of manifest destiny meant that their lands would be occupied and annexed. Ultimately manifest destiny would lead to confrontations, wars, Indian removal from their land, limited rights for indians and expansion of slavery.
