Manifest Destiny was the belief held by many Americans in the 19th century that the United States was destined to expand from coast to coast. Those who supported Manifest Destiny believed that it was inevitable for the United States to extend its territory westward. They had several reasons for believing this:

1. Economic Opportunities: Supporters of Manifest Destiny believed that the western territories held immense economic potential. They saw the abundant natural resources, such as fertile land for agriculture, forests, minerals, and access to trade routes, as opportunities for economic growth.

2. Spread of Democracy: Many Americans believed in the virtues of democracy and saw the expansion of the United States as a way to spread these democratic principles. They believed that by expanding, the United States could promote democracy and American ideals throughout the continent.

3. God's Will: Some Americans, particularly those with religious convictions, saw Manifest Destiny as a divinely ordained mission. They believed that God favored the expansion of the United States and that it was their duty to fulfill God's plan by spreading American values and civilization.

4. National Security: Supporters of Manifest Destiny also argued that by expanding westward, the United States would be able to secure its borders and protect its citizens from potential threats. They believed that controlling the entire continent would provide greater security and a buffer zone against potential adversaries.
