Manifest Destiny Lecture Notes

Introduction

  • John Louis O'Sullivan coined "Manifest Destiny" in 1845, advocating for the annexation of Texas.
  • Manifest Destiny: Belief in the U.S.'s mission to spread democracy and its destiny to expand across the continent.
  • Supported by the Democratic Party's Young America movement, emphasizing national unity and American exceptionalism.
  • Not universally accepted; critics like Ralph Waldo Emerson and Abraham Lincoln viewed it as imperialism and critiqued aggressive expansion.

Antebellum Western Migration and Indian Removal

  • Post-War of 1812: Rapid settlement in Great Lakes due to aggressive land sales.
  • Native American removal central to expansion, e.g., Florida annexation and Seminole Wars.
  • Indian Removal Act (1830): Authorized negotiations for Native American relocation west of the Mississippi.
  • Cherokee Trail of Tears: Forced relocation leading to the death of thousands; legal battles like Worcester v. Georgia.

Life and Culture in the West

Texas, Mexico, and the United States

  • Texas Revolution (1835-1836): Resulting in independence from Mexico; fueled by disagreements over slavery and governance.
  • U.S. annexation of Texas (1845) seen as aggression by Mexico, leading to the Mexican-American War (1846-1848).
  • Treaty of Guadalupe Hidalgo (1848): U.S. gains significant territory; exacerbates slavery debate.

Manifest Destiny and the Gold Rush

  • California Gold Rush (1848): Mass migration fueled by gold discovery; led to rapid urban growth and social tensions.
