During the 19th century, the US was constantly expanding westward. Due to the idea of Manifest Destiny, the federal government strived to add as much territory to the US in order to connect the two sides of the continent. This resulted in the US gaining a significant amount of territory.
This increase in territory resulted in the federal government creating policies that encouraged American citizens to move west. One example would be the Homestead Act, which gave 150 acres of land to any American willing to move west.
Explanation: Though the journey west was dangerous and long, many people went. Farmland in the east was scarce an expensive: relatively few people owned most of it. The lure of the availability of farmland out west was attractive to a still predominantly agrarian population. The settling of western lands was part of the U.S.'s "Manifest Destiny."
