What factor encouraged americans to move to the west in the1800s

In 1853, the Gadsden Purchase provided Americans with an additional 30,000 miles of land from Mexico to settle. This land included the southern parts of the states of Arizona and New Mexico. In addition to all of the opportunity that the new land offered, many Americans felt that it was their duty as Americans to settle this new land and bring democracy to all of the people living there. :)

There was no room for farming or agriculture, and there was a lot of agriculture in the East. These are three major things that  made people want to move to the West where there was room for farming and agriculture! The soil was fertile and the land was spaious and sometimes free. who would not want go to the west!
