In what ways did the Us government encourage West ward expansion in the 1800 s?

In the 1800s, the U.S. government encouraged westward expansion through various policies and initiatives. The Louisiana Purchase in 1803 significantly increased the nation's territory, while the Homestead Act of 1862 offered 160 acres of land to settlers willing to cultivate it for five years. Additionally, the construction of railroads, supported by government land grants, facilitated travel and trade, making western lands more accessible. The government also engaged in treaties and military actions to secure land from Native American tribes, further promoting settlement.
