What this topic is asking
Topic 4.4 asks you to explain how the early republic asserted itself abroad. The arc runs from defending American shipping in the War of 1812 to proclaiming leadership of the entire Western Hemisphere in the Monroe Doctrine, with the surge of nationalism in between. The exam wants the growing confidence, and the limits of American power that still lay behind it.
The War of 1812 abroad
Diplomatic gains: the Adams-Onis Treaty
Confidence translated into territory. In the Adams-Onis Treaty (1819), negotiated by Secretary of State John Quincy Adams, Spain ceded Florida to the United States and the two powers fixed the boundary of the Louisiana Territory, extending American claims toward the Pacific.
