Expansionists justified the idea of manifest destiny and the acquisition of new territory because they were spreading what?

Answer: spreading democracy and capitalism across the entire North American

Explanation:Manifest Destiny, a phrase coined in 1845, is the idea that the United States is destined-by God, its advocates believed-to expand its dominion and spread democracy and capitalism across the entire North American continent. The philosophy drove 19th-century U. S. territorial expansion and was used to justify the forced removal of Native Americans and other groups from their homes. The rapid expansion of the United States intensified the issue of slavery as new states were added to the Union, leading to the outbreak of the Civil War.
