Lee's Push-Pull Theory
Lee's theory of migration is based upon three elements:
1. Place of Origin
2. Place of Destination
3. Intervening Obstacles
There are some postive (push) and some negative (pull) factors. These factors vary between person to person. Push factors at the Place of Origin compel a migrant to emigrate. Pull factors at the Place of Destination at attract to immigrants.

Manifest Destiny
Manifest Destiny:The 19th-century doctrine or belief that the expansion the US throughout the American continents was both justified and inevitable.
Manifest destiny played its most important role in, and was coined during the course of, the Oregon Border dispute with Britain. The Anglo-American Convention of 1818 had provided for the joint occupation of the Oregon Country, and thousands of Americans migrated there in the 1840s over the Oregon Trail.The British rejected a proposal by President John Tyler to divide the region along the 49th parallel, and instead proposed a boundary line farther south along the Columbia River, which would have made most of what later became the state of Washington part of British North America. Advocates of manifest destiny protested and called for the annexation of the entire Oregon Country up to the Alaska line Presidential candidate James K Polk. used this popular outcry to his advantage, and the Democrats called for the annexation of "All Oregon" in the 1844 Presidential Election.

Expansion
Expansion:Extension of a state's territory by encroaching on that of other nations, pursued as a political strategy.
At the beginning of the 1800s, the US was formally comprised of sixteen states: the original thirteen colonies have been recognized as independent by the Treaty of Paris in 1783 and the states of Vermont, Kentucky and Tennessee having been added to the union by 1796. But American trappers and settlers were busily expanding to other areas, and the country was growing rapidly. Americans did not question their right to colonize vast expanses of North America beyond their country's borders. By the mid-1840s, United States expansionism was expressed in terms of "manifest destiny, and by the end of the nineteenth century, the US had acquired all of its current territory through a series of wars and peaceful acquisitions.
