What was a significant ideological division among Americans regarding foreign policy during the period?

The significant ideological division among Americans regarding foreign policy during this period was primarily centered around the French Revolution. Following the American Revolution, the French Revolution ignited passionate debates in the United States. Some Americans supported the revolution as an extension of their own fight for liberty and viewed it as a continuation of Enlightenment ideals. They admired France's pursuit of liberty and equality.

Conversely, other Americans were wary of the revolution, particularly due to its radical aspects and the violence associated with it, including the Reign of Terror. This division reflected broader ideological rifts in American society, particularly between those who were more favorable towards the French (often those aligned with the Jeffersonian Republicans) and those who supported a more cautious approach, which was favored by the Federalists. The implications of this division were far-reaching, influencing American foreign policy decisions and alignments during the late 18th and early 19th centuries.

Support for British monarchy, opposition to immigration, and support for isolationism did not evoke the same level of intense ideological division regarding foreign policy during this period. The debates surrounding the French Revolution were pivotal and shaped the emerging political landscape in the United States.
