Storyboard Text

  • LOUISIANA PURCHASE
  • TIMELINE: U.S. TERRITORIAL ACQUISITIONS, 1803-1959
  • As a young, ambitious country, the United States aimed to continue expansion. In 1803, with Thomas Jefferson as president, the U.S. brokers a deal with France for the Louisiana Purchase. The acquisition doubles the size of the United States.
  • FLORIDA ACQUISITIONS
  • Under President James Monroe, the U.S. fiercely contests Spain for control of both East and West Florida. Spain, weakened from war with France, cedes Florida to the U.S., even despite controversial military moves by General Andrew Jackson.
  • Farewell, Spain! Florida is OURS!
  • TEXAS ACHIEVES INDEPENDENCE
  • As American settlers poured into Northern Mexico, so did their ideas of independence and autonomy. After warring with Mexico for over three years, Texans finally achieve independence, remaining their own republic for nine years.
  • OREGON TERRITORY
  • MEXICAN CESSION
  • All this new territory!
  • We've defeated Mexico!
  • OREGON 35 MI.
  • Desiring Texas, and fueled by the idea of manifest destiny, the U.S. initiates war with Mexico. After nearly three years of fighting, the U.S. defeats Mexico, and is awarded nearly 55% of Mexico's territory; it is now the entire Southwest U.S.
  • While at war with Mexico, the U.S. also found themselves contesting Great Britain over the Oregon Territory. Tensions rose, as did the cry for war. However, the territory was peacefully divided at the 49th parallel, and war averted.
  • ALASKA AND HAWAII BECOME STATES
  • The last two states to enter the Union were Hawaii and Alaska, both in 1959. Hawaii was previously imperialized and made a territory in 1893. Alaska was purchased from Russia in 1867 for $7.2 million dollars.
