Outline of the expansion of the West Western expansion was seen as the central theme of American history until the end of the 19th century, and it became a major factor that formed the history of the United States. As Frederick Jackson Turner said, the greatest power or influence in shaping American democracy and society is that there are so many free lands in America, which has a great impact on American society It was. After the motive revolution, the independent victory opened the Western countries, after which stable settlers to the Mississippi Valley continued.
The expansion to the west side of the United States in the 1840s united the white Americans and the expansion of slavery in the western division of white Americans. A few months after President Pork took office, John O'Sullivan imagined "the obvious fate of a white American - the entire continent that Providence gave us." This racist ideology was favored when the Mexican American war (1846 - 1848) began. War propagators defined the United States as bringing freedom and civilization to the backward Mexicans. From the loot, the United States almost took away the current southwestern part of the United States from Mexico - this is plunder of huge land, which reflects continued violence and seizure of black soil in the United States.
The story of the United States is one of the expansion of the west starting from the east coast and continuing everywhere in the continent of Africa - sometimes it is late, and at other times it will leap. Even before American colonies acquired independence from the UK, settlers began to move west to include the territory of modern Kentucky and Tennessee. Purchased in Louisiana in 1803, this is the largest territorial benefit in the history of the United States, and it is of great help to the western extension of the country. After the war of 1812, when Americans headed for gold, temptation of land, and obvious destiny, the population of the western region began to expand.
By the mid-1950's, Canadian state politicians began to consider west expansion. They asked about Rupert 's land and Hudson' s Bay 's terms of office in the Arctic Circle and made a series of exploratory explorations to familiarize themselves and Canadian people with the geography and climate of the area. Effective governance in the unified state of Canada since 1840 requires a careful balance between the Catholic and the Protestant, the interests of the population of France and the UK. John A. Macdonald appeared in the 1950's and was suitable for this work.
