What was a key reason for the U.S. expansionism during the late 19th and early 20th centuries?

The focus on securing new markets for American goods was a pivotal reason for U.S. expansionism during the late 19th and early 20th centuries. As the United States rapidly industrialized, there was an increasing need for additional markets to absorb the surplus production of goods, as well as a demand for raw materials to fuel this industrial growth. Expanding into territories abroad allowed the U.S. to reach new consumers and resources, enhancing its economic strength and competitiveness on the global stage.

The desire for new markets was also intertwined with the broader ideology of Manifest Destiny, which held that it was the United States' destiny and duty to expand its influence and culture. This expansionism was seen as not only beneficial but essential for the economic prosperity of the nation, contributing to a more competitive and robust economy. By looking outward and establishing trade relationships or direct control over new territories, the U.S. could thrive economically in a world that was increasingly interconnected through trade and industry.
