Aftermath of World War I

  • Woodrow Wilson's 14 Points aimed to promote democracy but failed in implementation.

  • Colonial hopes for independence, such as in India and Vietnam, were disappointed.

Global Political Developments

  • Ho Chi Minh and Gandhi were inspired by Wilson but denied their nations' self-rule.
  • The Ottoman Empire dissolved, with British and French mandates taking control of Middle Eastern territories.
  • Italy, led by Mussolini, felt betrayed by postwar settlements, fueling the rise of fascism.
