Final answer:
US foreign policy saw considerable change from 1783-1828, starting with a focus on neutrality under George Washington to a more assertive Monroe Doctrine. The early period involved avoiding European conflicts, while the later years were marked by diplomatic engagement to protect American interests and hemispheric influence.
Step-by-step explanation:
The extent of change in US foreign policy from 1783-1828 was significant as it evolved from the policies of neutrality and isolation established by George Washington to the more assertive stance embodied in the Monroe Doctrine of 1823. Under Washington, the nation focused on internal development, avoiding entanglement in European affairs while striving to maintain sovereignty and facilitate economic recovery. Issues with Britain and Spain over borderlands and navigation rights were key challenges. With the Monroe Doctrine, the US took a more assertive role, declaring the Western Hemisphere closed to European colonization and asserting that any attempt by Europeans to influence the region would be seen as an act of aggression.
The 1790s saw Americans deeply divided over foreign affairs, particularly in reference to relations with France during its revolutionary period. American history is marked by how international developments have influenced domestic policy, evident during the Federalist Era, as the experiences of the early US presidents set precedents for the conduct of foreign policy that resonate into the twenty-first century.
