Answer:
The amount to which the United States has impacted other countries' economies, military, and cultures is referred to as "American imperialism." The "American Empire" that James K. Polk's administration initially envisioned didn't come to fruition until the late 1800s. During this age of economic expansion, Americans sought out new global markets for the sale of their goods. People came to believe that the United States was entirely responsible for the introduction of superior civilizations like the United States to "savage" nations all over the globe as social Darwinism gained popularity. The rise of imperialism in the United States was fueled by these and other factors.
American imperialism is rooted in the conviction that the United States is unique among countries due to its special worldwide mission to promote freedom and democracy. "Proceeding along a route to which no end can be identified" is often credited as the root of this theory, based on Tocqueville's 1800s observation.
