Spreading westward, the pioneers of the 19th century entered the western part of America, being promoted by the gold rush including Louisiana, the Oregon trail, and the belief in "critical destiny".
But the border also involves the expansion of slavery. The expansion of slavery to the West is one of the most dynamic economic and social processes being done in this country. The expansion to the west brought slavery to the Southwest, Mississippi State of Alabama, and across the Mississippi River to Louisiana. Finally, by the 1840's, it was poured into Texas. Therefore, the expansion of slavery was not just a political issue but a major political issue in the 1850s. All the Americans experienced the facts of life during this time.
Why is it important to expand to the west and why is it expanding to the west? There is a complete continent to explore, various climates, geographical features, vegetation, animals, raw materials and so on. The possibility of new resources and large land is waiting for American settlers to discover that some of the land is almost free. Westward Expansion gives people the opportunity to find new houses and jobs, experience adventure, explore possibilities, find gold and silver, remove civilization restraint, and start over. In other words, Westward Expansion makes it possible for people to live "American dreams". For a variety of practical reasons, Americans have a motive to move westward, but their inspiration is God's will to come from the obvious fate of America.
Between 1783 and 1912, it can be said that all Americans participated in the expansion of the United States. During this period, all the US presidents led the expansion. The treaty was promulgated by politicians and diplomats. These wars were initiated by the military and American citizens. Henry Clay has announced the "American System" including subsidized traffic infrastructure for new roads and canals. During the industrial revolution, the inventors have made possible a new transportation system like a railroad. Entrepreneurs will invest in these systems. However, it was an American who built these systems, making Westward Expansion executable, helping settlers and settlers travel west and build new lives on new lands.
