Manifest Destiny was a popular belief in the mid-to-late 19th century. Its proponents claimed that the United States had the divine right to expand westward—meaning that U.S. expansion was the will of God.
In this regard, how did manifest destiny shape the American West?
The philosophy drove 19th-century U.S. territorial expansion and was used to justify the forced removal of Native Americans and other groups from their homes. The rapid expansion of the United States intensified the issue of slavery as new states were added to the Union, leading to the outbreak of the Civil War.
Keeping this in consideration, what were two main causes of manifest destiny and westward expansion?
The idea of Manifest Destiny arose in response to the prospect of U.S. annexation of Texas and to a dispute with Britain over the Oregon Country, which became part of the union.
