context_page_description: The history of U.S. foreign policy from 1801 to 1829 concerns the foreign policy of the United States during the presidential administrations of Thomas Jefferson, James Madison, James Monroe, and John Quincy Adams. International affairs in the first half of this period were dominated by the Napoleonic Wars, which the United States became involved with in various ways, including the War of 1812. The period saw the United States double in size, gaining control of Florida and lands between the Mississippi River and the Rocky Mountains. The period began with the First inauguration of Thomas Jefferson in 1801. The First inauguration of Andrew Jackson in 1829 marked the start of the next period in U.S. foreign policy.
  Upon taking office, President Jefferson dispatched envoys to the French First Republic to purchase the city of New Orleans, which held a strategic position on the Mississippi River. French Emperor Napoleon instead offered to sell the entire territory of Louisiana; the Jefferson administration accepted the offer, and the subsequent Louisiana Purchase doubled the size of the United States.

French Emperor Napoleon instead offered to sell the entire territory of Louisiana; the Jefferson administration accepted the offer, and the subsequent Louisiana Purchase doubled the size of the United States. During Jefferson's second term, the United Kingdom of Great Britain and Ireland escalated attacks against American shipping as part of a blockade against France. These attacks continued under President Madison, and in 1812 the United States declared war against Britain, beginning the War of 1812. Defying Madison's hopes that the war would end with the quick capture of Canada under British rule, the War of 1812 continued inconclusively until 1815. The Treaty of Ghent provided for a return to status quo ante bellum borders, and the final defeat of Napoleon later in 1815 ended the issue of British and French attacks on American shipping. 
  Though the war with Britain was inconclusive, the U.S. defeated Native American allies of Britain at the Battle of the Thames and the Battle of Horseshoe Bend, ensuring U.S. control of the Old Northwest and the Old Southwest. In the aftermath of the war, the United States and Britain signed two treaties that eased tensions, settled border disputes, demilitarized the Great Lakes, and provided for the joint occupation of Oregon Country. A separate treaty with the Russian Empire established the southern border of Russian America and opened Russian ports to U.S. trade. In 1819, the United States and the Kingdom of Spain agreed to the Adams–Onís Treaty, through which Spain transferred control of Florida to the United States. Numerous Latin American countries gained independence from Spain during Monroe's presidency. In 1823 he promulgated the Monroe Doctrine, under which the U.S. pledged to oppose all future efforts to colonize the Western Hemisphere.
