How did manifeast destiny change peoples lives?

Answer 1

Manifest Destiny, the 19th-century belief that the expansion of the United States across the American continent was both justified and inevitable, significantly changed people's lives by promoting westward migration. This led to the displacement of Native American tribes, the establishment of new settlements, and economic opportunities for many settlers. However, it also intensified conflicts over land and resources, contributing to tensions that would later erupt into the Civil War. Overall, it reshaped the social, political, and economic landscape of the nation.
