Lyons 1 Noah Lyons Professor Garrison American History September 7, 2018 Heartland Response Onward Expansion Manifest Destiny, which was the belief to expand to the west, happened shortly after the Civil War. Settlers started moving west for better opportunities. For example, they moved west to own land, to get rich by the mines, or to start a new life somewhere else. Eventually, people start finding gold in mines and minerals, and that made moving to the west more significant for the American settlers. Americans would hire Chinese workers because the work in the mines was extremely dangerous and lethal. The workers were underpaid and uncared for. On another subject, the industry for cowboys came into play, and they would oversee the cattle. The cattle were open ranged, which allowed them to graze and move freely throughout the plains. However, Joseph Glidden came up with the invention of barbed wire, and it changed the way cattle grazed. Around time as well, the Americans killed most of the buffalo population and left a lot of the bones and meat on the buffalo. The Native Americans would use all the buffalo, but the Americans did not use all of it.
