Detailed Study Notes on World War I

WORLD WAR ONE

OVERVIEW OF WORLD WAR I

  • Reputation: Referred to as "The War to End All Wars."
  • Initial American Attitude:
    • At the start of the war, many Americans believed it was unimportant for the U.S. to engage in the conflict.
    • The United States aimed to maintain neutrality, largely due to a significant population of over 8 million Germans residing in America.
  • Economic Motivations:
    • President Woodrow Wilson believed the U.S. could profit by selling arms to both sides in the conflict.
  • Consequences of Neutrality:
    • As the U.S. began selling weapons, the British confiscated American ships bound for Germany.
    • German forces sank American ships heading to England.

CAUSES OF THE WAR

  • Secret Alliances:
    • Many nations were intertwined in secret alliances that were not widely known.
  • Industrialization:
    • European nations became industrialized and started competing with each other in producing manufactured goods.
  • Nationalism:
    • Nations prioritized their own interests over those of others, raising tensions.
  • Imperialism:
    • European powers expanded their empires and competed for control over international markets.
  • Militarism:
    • Nations competed to build powerful military forces, particularly armies and navies.
  • Ethnic Pride:
    • Ethnic groups often placed greater importance on ethnic identity than on political borders.
  • Self-Determination:
    • Conquered peoples wanted the ability to control their own futures.

SPARK OF THE WAR

  • Assassination of Archduke Franz Ferdinand:
    • The heir to the Austro-Hungarian Empire was assassinated by members of the Black Hand during a tour in Sarajevo, which intensified the existing conflicts.

ALLIANCES

  • The Triple Alliance:
    • Composed of Germany, Austria-Hungary, and Italy.
  • The Triple Entente:
    • Comprised of France, England, and Russia.

GERMANY’S STRATEGY

  • Von Schlieffen Plan:
    • Objective: Launch an attack on France via Belgium in order to quickly eliminate them from the war.
    • Once France was defeated, Germany intended to redirect its efforts toward Russia.
    • Outcome: The plan failed as France resisted longer than Germany anticipated; the war devolved into trench warfare after initial German advances toward Paris were halted.

FRONTLINES OF THE WAR

  • Two Front War:
    • Eastern Front: Fought against Russia.
    • Western Front: Fought against England and France (with later involvement of the United States).

AMERICAN NEUTRALITY

  • Diverse American Identity:
    • The presence of many immigrants from the warring nations meant the American population was divided in its loyalties.
    • People began to identify as German-Americans, Jewish-Americans, etc.
  • Concerns Over Warfare:
    • The invasion of Belgium sparked outrage amongst Americans as it was a neutral country.
    • German submarine warfare became a concern, particularly the sinking of the Lusitania leading to over 100 American deaths, along with the Sussex which cost 80 American lives.
    • Germany targeted American supply routes to England to weaken their efforts against Germany and Austria-Hungary.

EVENTS LEADING TO U.S. INVOLVEMENT

  • Zimmerman Note:
    • A secret message sent by Germany to Mexico proposing an alliance if Mexico would attack the United States.
    • This note was intercepted by the British and passed to American officials, further inflaming tensions.
  • Public Sentiment:
    • Some Americans argued against involvement on moral grounds, referencing George Washington’s farewell address against foreign entanglements and highlighting costs associated with participation.
    • Others pointed out that the U.S. had not been invaded and did not require additional territory.
  • Wilson's Justification for War:
    • President Wilson stated that "the world must be made safe for Democracy," prompting Congress to approve war against the Central Powers.

TOTAL WARFARE

  • Definition:
    • Total warfare emerged, meaning all participants viewed everyone as enemies and utilized all necessary means to achieve victory.
  • Manufacturing Impact:
    • Nations rapidly produced new types of weaponry to support war efforts.

NEW WEAPONS DEPLOYED IN THE WAR

  • Types of Weapons Used:
    • Airplanes: The U.S. initially lacked aircraft.
    • Tanks: Developed initially by Great Britain.
    • Mustard Gas: A chemical weapon causing severe burns.
    • Chlorine Gas: Attacked soldiers' lungs; other gases affected the central nervous system.
    • Submarines: Utilized primarily by Germany.
    • Machine Guns: Changed warfare to a defensive strategy; direct charges against machine guns were futile.
    • Trench Warfare:
    • Trenches averaged 4 feet wide and 8 feet deep.
    • Soldiers faced muddy conditions; trenches were fortified using sandbags and wooden platforms.

UNRESTRICTED SUBMARINE WARFARE

  • Conditions of Engagement:
    • Traditional rules dictated that military ships must give trading ships a 30-minute warning before attack.
    • Submarines, by nature of their design, could not provide such warnings; thus, they caused widespread panic.
  • Notable Incidents:
    • Sinking of the Lusitania, a cruise liner carrying American passengers and arms, violated established maritime law and escalated tensions with the U.S.

ZIMMERMAN NOTE ANALYSIS

  • Content of the Note:
    • The note from Germany to Mexico sought a military alliance, promising Mexico the recovery of territory (including Texas, New Mexico, and Arizona) if they engaged the United States.
    • The interception of this note was pivotal in swaying U.S. public opinion towards supporting military involvement in the conflict.
