The reasons why American Indians were forced to migrate from east to west around 1830 ..

1may 28th, 830: the us congress passed the Indian migration act, forcing all Indians to migrate to the west of the Mississippi river. Indians were driven to today's 2 18 designated settlements (reservations), and immigrants spread all over the North American continent.

The United States expanded to the west of the Mississippi River and annexed large areas of France, Spain, Britain and Mexico by means of purchase and war. Because the American government promulgated a series of land laws and bought a large area of land in Louisiana from France, immigrants felt that colonial activities were guaranteed to some extent and flocked to the west to explore Ohio, Kentucky and Tennessee, laying the foundation for the growing grain-producing areas in the midwest.

The westward movement had a great influence on American political and economic life. The vast western land is merged into the United States, making the United States a country with a vast territory and rich natural resources; The large-scale development of the western region has led to large-scale railway construction and a large number of immigrants outflow, forming a vast domestic market in the United States.

The process of American developing the west is also the process of American urbanization, industrialization and great integration of American nation. The westward movement completely changed the face of the United States: large areas of wasteland were reclaimed, and a large number of capitalist farms were established. The development of agriculture in the west provided a large number of grain, raw materials, export products and domestic markets for industrial development; It has changed the layout of the labor force in the United States, promoted the formation of a unified domestic market and the rapid development of complementary trade between East and West. The development and utilization of resources in the western region has also met the needs of industrial development, and the transportation industry has also developed rapidly.
