4.4 America on the World Stage

In the early 19th century, the United States worked to establish itself as an independent power on the global stage. After the Revolutionary War and the War of 1812, American leaders defined foreign policy around neutrality, territorial expansion, trade, and resistance to renewed European intervention in the Americas.

What to Know About America on the World Stage

  • British impressment violated American neutrality, while Jefferson's Embargo Act tried to pressure European powers but proved ineffective against Britain.
  • War Hawks called for war over violations of American rights, but the War of 1812 ended without addressing its original causes.
  • The British blockade increased American manufacturing, while the war weakened Native American resistance and contributed to the Federalist Party's decline.
  • The Adams-Onís Treaty gave the United States Florida, and government-sponsored expeditions gathered information to support western expansion.
  • The Monroe Doctrine opposed new European colonies and intervention in the Americas, while stating that the United States would not interfere in European affairs.
  • The Indian Removal Act authorized relocation of eastern tribes west of the Mississippi, and the Trail of Tears forcibly relocated Cherokee and other tribes.

Foreign Policy Challenges and the War of 1812

The young American republic faced significant challenges from European powers, particularly Britain and France, who were engaged in the Napoleonic Wars. American neutrality was repeatedly violated as these nations competed for global dominance:

  • Impressment: British ships seized American sailors and forced them into service in the Royal Navy
    • Violated American sovereignty and neutrality
    • Approximately 6,000 Americans were impressed between 1803-1812
  • Trade Restrictions:
    • British Orders in Council prohibited neutral ships from trading with France
    • Napoleon's Continental System forbade European allies from trading with Britain
    • American ships were caught in the middle, facing seizure by both powers
  • The Chesapeake Affair (1807):
    • British warship HMS Leopard attacked USS Chesapeake
    • Three American sailors killed, four forcibly taken by the British
    • Provoked intense anti-British sentiment in America
  • Jefferson's Response:

The Embargo Act of 1807

  • Prohibited all American overseas trade
  • Intended to use economic pressure to force European respect
  • Effects:
    • Devastated American economy, especially New England shipping
    • Proved ineffective against Britain, who found alternative trade sources
    • Eventually replaced by the Non-Intercourse Act (1809)

The War of 1812: "The Second War of Independence"

The continuing violations of American rights led to growing calls for war, particularly from the "War Hawks" in Congress:

Causes of WarAmerican War Aims
Maritime violations (impressment, trade restrictions)Defend maritime rights
British support of Native American resistanceEnd British alliance with Native Americans
Desire to annex British CanadaTerritorial expansion
National honor and independenceAssert American sovereignty

Key events of the war:

  • Failed American invasion of Canada (1812)
  • British naval blockade of American coast
  • British burning of Washington, D.C. (1814)
    • In retaliation for Americans burning York (Toronto)
    • White House and Capitol building destroyed
  • Battle of Fort McHenry (1814)
    • Francis Scott Key wrote "The Star-Spangled Banner"
  • Battle of New Orleans (January 1815)
    • Andrew Jackson's decisive victory (after peace treaty was signed)
    • Made Jackson a national hero

Treaty of Ghent (December 1814):

  • Restored prewar territorial boundaries
  • Ended the fighting without addressing the original causes of the war
  • No territorial gains by either side

Effects of the War:

  • Increased American manufacturing due to the British blockade
  • Enhanced American national prestige
  • Weakened Native American resistance in the Northwest and South
  • Contributed to the decline of the Federalist Party following the Hartford Convention
  • Ushered in the "Era of Good Feelings" under President Monroe
  • Reinforced the goal of protecting and encouraging American foreign trade, since the nation's independent standing depended on commerce with other countries and freedom from European restrictions on it

Territorial Expansion and the Monroe Doctrine

Following the War of 1812, the United States pursued an aggressive policy of territorial expansion and diplomatic assertion:

Territorial Acquisitions:

  • Adams-Onís Treaty (1819)
    • Spain ceded Florida to the United States
    • Established boundary with Spanish Mexico
    • Negotiated by Secretary of State John Quincy Adams

Exploration Efforts:

  • Lewis and Clark Expedition (1804-1806)
  • Other government-sponsored expeditions to map western territories
  • Scientific and commercial information gathering to support expansion

The Monroe Doctrine (1823):

  • Context: European powers considering intervention in Latin American independence movements

  • Key principles:

    1. Non-colonization: European powers should not establish new colonies in the Americas
    2. Non-intervention: European powers should not interfere in the affairs of independent nations in the Western Hemisphere
    3. Separate spheres: The United States would not interfere in European affairs
  • Significance:

    • Declared American sphere of influence in the Western Hemisphere
    • Asserted U.S. opposition to European colonialism in the Americas
    • Initially had limited practical effect (relied on British naval power)
    • Became cornerstone of American foreign policy in later decades

Native American Policy and Removal

As America expanded westward, its relationship with Native American nations became increasingly hostile:

  • Native American Resistance:
    • Tecumseh's Confederacy attempted to unite tribes against American expansion
    • Native alliances with British during War of 1812
  • Systematic Removal Policies:
    • First Seminole War (1817-1818): Andrew Jackson invaded Spanish Florida
    • Indian Removal Act (1830): Authorized relocation of eastern tribes to lands west of Mississippi
    • Trail of Tears (1830s): Forced relocation of Cherokee and other tribes
      • Thousands died during the journey
  • Legal Battles:
    • Worcester v. Georgia (1832): Supreme Court recognized Cherokee sovereignty
    • President Jackson ignored the ruling: "John Marshall has made his decision; now let him enforce it!"

The American government's policy toward Native Americans revealed the tensions between America's democratic ideals and its territorial ambitions. This pattern of expansion and dispossession would continue throughout the 19th century as the United States claimed land across the continent.

The early 19th century marked America's emergence as a regional power with growing global ambitions. Through war, diplomacy, and territorial expansion, the United States established its presence in the Western Hemisphere and laid the groundwork for future international influence. While still lacking the military and economic might of European powers, America had begun to define its unique role in world affairs based on principles of republicanism, independence from European entanglements, and hemispheric dominance.
