The Great American Expansion

With the development of ideas and inventions of the early 19th century, the United States is rapidly changing. One of the main reasons the United States prospered in the late 19th century was the installation of a railway system. Efforts to build a railroad in the United States began in the 1930s and continued until the 1870s. Railroads have become an important system to guide settlements and bring economic opportunities to the majority of the United States. The railway provides the opportunity for people to access the places they can not travel and to develop the town.

Do you remember how you understood the great expansion of America in the 19th century? When the settlers headed to the west, understood our clear fate, brought agriculture, civilization, and prosperity to the center of America? Well, I think Berry has unraveled this effort in the second half of the 20th century. Thousands of small farmer's towns are empty, ruined, millions of farmers like sentinel in one quarter of lush land are now unpopular and unpopular. Hundreds of American cities based on domestic agriculture are now being destroyed and these cities are bankrupt

The expansion to the west of agriculture has increased pressure on American Indian countries and exacerbated the intermittent war with them. The expansion of American agriculture to the west side is based on military conquest and expulsion of Native Americans. The Mexican war between 1846 and 1948 also included expansion to the western part, but this time it sacrificed Mexican and Indians. Part of the civil war was due to the discussion on whether expansion of these new lands and the agricultural labor force there is slave or free. Separatists who promised slavery believe that the demand for southern cotton forces the UK and other countries to support the union. As the supply of wheat in the south and northern was interrupted, southern agriculture continued to exist for the majority of the war maintained by slave labor force; the main change was the large cotton to corn and other food It was a diversification of crops.
