In the 1800s, the federal government encouraged migration to the West in many ways. This U.S. expansion had a major influence on the world. Expansion to the West brought in railroads, new cities, gold mines, new fields, more money, and more. The country's expansion came with many positive things, but also some negatives. Americans began to believe it was their duty to expand their territory across North America. This faith has been called Destiny Primordial. One way that the federal government took action that led to expansion to the West was to buy land.
The Southern economy has become increasingly dependent on "King Cotton" and the forced labor policy that has maintained it. Meanwhile, more and more Northerners came to believe that the expansion of slavery impeded their own freedom, both as citizens –themajority pro-slavery in Congress did not seem to represent their interests–and as yeoman farmers. They did not necessarily object to their own slavery, but resented the way their expansion seemed to compete with their own economic opportunity.
After two years of increasingly contentious debate on the issue, another compromise was proposed by Kentucky Senator Henry Clay. This had four parts: first, California would join the Union as a free state; second, the future of slavery in the rest of Mexico's territories would be determined by the citizens who lived there; third, slave trading (but not slavery) would be abolished in Washington, D.C.; and fourth, a new Fugitive Slave Act would allow Southerners to recover fugitive slaves who had fled to northern states where they lived.
