Overview

This lecture reviews the major social, technological, and political changes occurring in America around 1900, setting up key themes for upcoming study units.

The Closing of the American West

  • By 1900, the American frontier was considered closed due to settlement and expansion.
  • Native American tribes were confined to reservations, and buffalo populations were decimated.
  • Homesteads (farms given to settlers) and barbed wire ended open land and free-range practices.

Industrial Expansion and Urbanization

  • Oil was first discovered in Titusville, Pennsylvania in 1859, leading to major new oil fields in states like Texas and Oklahoma.
  • Figures like John D. Rockefeller amassed great wealth from the booming oil industry.
  • Steel production, led by Andrew Carnegie, allowed cities to grow vertically and expand rapidly.
  • Industrialization spurred urbanization, with cities like Chicago transforming into major population centers.

Political Developments and Shifts

  • After the Civil War, Reconstruction aimed to rebuild the South, with limited success and lasting racial issues.
  • William McKinley (president from 1896–1901) was assassinated, succeeded by Theodore Roosevelt.
  • Roosevelt changed American domestic and foreign policy, promoting conservation and expansion abroad.

Emergence as a Global Power
