Westward Expansion (1807-1912) The Surge West. Summary. The westward movement of the American population occurred in intermittent flurries of settlement. The first began early in the nation's history, resulting in the statehood of Vermont, Kentucky, Tennessee, and Ohio, all of which were admitted to the Union between 1791 and 1803.
As the United States grew in power, so did her ideas of expansion. The foreign powers were beginning to move out of their continents and seek land in other countries. The United States soon followed. They followed in their founderâs footsteps and tried to occupy lands in the far seas. However, in the beginning, this need for more land was called Manifest Destiny. This idea claimed that God was forcing them to occupy the new western lands. The expansionism that occurred in the late 1800âs was not a result of Manifest Destiny, and thus this new idea of expansionism was different from the expansionism ideas of early America.
