WWI Comprehensive Study Guide: Causes, Conflict, and Consequences

SECTION 1: CAUSES OF WWI

• The MAIN Causes (Long-term Causes):

  • The origins of the war are categorized by the acronym MAIN, representing four systemic factors that created volatile conditions in Europe.

  • Militarism: The rapid buildup of armies and navies alongside an intense arms race. European nations, particularly Germany and Britain, competed for naval supremacy, specifically through the construction of Dreadnought battleships. By the year $1914$, Europe possessed the largest standing armies in human history. This large-scale military readiness increased the willingness of nations to resolve conflicts through force. Key statistic: Germany's military spending doubled between the years $1870$ and $1914$.

  • Alliances: Protective agreements between nations stating they would defend one another if attacked. This system effectively turned localized conflicts into a global war through a chain reaction.

    • Triple Entente (Allied Powers): Comprised of France, Britain, and Russia.

    • Triple Alliance (Central Powers): Comprised of Germany, Austria-Hungary, and Italy (though Italy later switched sides).

  • Imperialism: The practice of powerful nations exerting control over weaker territories to secure resources, establish new markets, and expand global power. This was driven by the Industrial Revolution's demand for raw materials, the desire for national prestige, and strategic military needs (such as naval bases).

    • Berlin Conference ($1884\text{--}85$): A meeting where European powers divided the African continent among themselves without any input from African peoples. Borders were drawn that ignored established ethnic groups.

    • Social Darwinism: A racist and dangerous justification for empire based on the belief in 'survival of the fittest' applied to nations. It held that 'stronger' nations had a right to dominate 'weaker' ones, leading to deep resentment and colonial conflict.

  • Nationalism: An extreme form of pride and devotion to one's nation, often executed at the expense of others.

    • Unification of Germany: Otto von Bismarck unified the German states through his policy of 'Blood and Iron' (war and military strength). He practiced Realpolitik, which is practical politics based on power dynamics rather than moral or idealistic concerns. Following the Franco-Prussian War ($1870\text{--}71$), Prussia defeated France and annexed the territory of Alsace-Lorraine, fueling long-term French resentment.

    • The Balkans: Known as the 'powder keg of Europe,' this region contained a dense mixture of ethnic groups (Serbs, Slavs, Austrians, Ottomans) with competing identities. Serbia sought to unite all Slavic people, a goal opposed by Austria-Hungary.

SECTION 2: OUTBREAK OF WAR

• The Spark (Trigger Event):

  • Assassination of Archduke Franz Ferdinand: On June $28, 1914$, the heir to the Austro-Hungarian throne was assassinated in Sarajevo, Bosnia.

  • The Assassin: Gavrilo Princip, a Bosnian-Serb nationalist and member of the 'Black Hand', a Serbian nationalist secret society.

  • Immediate Consequences: Austria-Hungary blamed Serbia and issued an ultimatum. Serbia’s partial refusal led Austria-Hungary to declare war on July $28, 1914$.

• The Domino Effect:

  • Russia mobilized its forces to defend Serbia due to their shared Slavic heritage.

  • Germany, honoring its alliance with Austria-Hungary, declared war on Russia and subsequently on France.

  • The Schlieffen Plan: Germany's military strategy designed to avoid a two-front war. The plan involved a rapid invasion of France through neutral Belgium, aiming to defeat the French in $6$ weeks before rushing troops east to confront Russia.

  • Great Britain's Entry: Britain had guaranteed Belgium's neutrality; when Germany invaded Belgium, Britain declared war on Germany. Within $6$ weeks, the alliance system had dragged all major European powers into a total conflict.

  • Failure of the Schlieffen Plan: The plan was unsuccessful because Belgium resisted longer than anticipated, Britain entered the war, and Russia mobilized its forces much faster than Germany predicted. This resulted in the Western Front becoming stuck in a stalemate of trench warfare.

SECTION 3: INDUSTRIAL WARFARE

• Propaganda:

  • Defined as biased or misleading information used to shape public opinion.

  • Governments utilized posters, films, and speeches to recruit soldiers, sell war bonds, maintain morale, and demonize the enemy.

  • Examples include the 'Uncle Sam Wants YOU' posters in the United States and the British white feather campaign, which shamed men not wearing military uniforms. It effectively dehumanized the enemy and engaged ordinary citizens in the war effort.

• Fronts of War:

  • Western Front: Characterized by static and brutal trench warfare primarily in France and Belgium. Battles like the Battle of the Somme and the Battle of Verdun saw massive casualties for minimal territorial gains.

  • Eastern Front: A more mobile conflict across larger territories involving Germany and Russia. While there was less trench warfare, Russia suffered enormous casualties (millions of soldiers) due to poor supply lines and leadership.

• New Industrial Weapons:

  • Machine guns: Made traditional infantry charges suicidal and directly led to the development of trench warfare.

  • Poison gas: Chlorine and mustard gas caused terror and horrific, slow deaths.

  • Tanks: Introduced by Britain in $1916$ to break through trench lines.

  • Airplanes: Initially used for scouting and reconnaissance, later evolving into dogfights and bombing missions.

  • Submarines (U-boats): Used by Germany to blockade Britain; notably responsible for the sinking of the Lusitania.

  • Artillery: Heavy shelling was responsible for the majority of casualties during the war.

SECTION 4: WAR OF ATTRITION & CULTURE OF WAR

• War of Attrition:

  • A strategy focused on wearing down the enemy's soldiers, resources, and morale until they can no longer resist.

  • The Battle of Verdun ($1916$) resulted in approximately $700,000$ casualties with no significant land gained.

  • The Battle of the Somme ($1916$) resulted in approximately $1 \text{ million}$ casualties within a few months.

• Poetry and Art:

  • There was a stark contrast between the government-propagated Appearance of War (heroic, patriotic adventure) and the Reality of War (mud, death, disease, shell shock/PTSD, and horror).

  • Wilfred Owen: A soldier-poet who wrote 'Dulce et Decorum Est' to describe a gas attack, calling the phrase 'it is sweet and right to die for your country' the 'old Lie.'

  • Siegfried Sassoon and Paul Nash: Soldiers who used their art and writing to expose the hellish reality of the trenches. Nash's paintings depicted a completely destroyed landscape.

SECTION 5: CHANGING TIDE OF WAR

• United States Entry (April $1917$):

  • Though initially neutral/isolationist, the U.S. joined the Allies for three main reasons:

    1. Unrestricted Submarine Warfare: German U-boats sank ships in British waters, including the Lusitania in $1915$, which killed approximately $1,200$ people, including $128$ Americans.

    2. Zimmermann Telegram ($1917$): A secret German proposal to Mexico for a military alliance against the U.S., intercepted by Britain.

    3. Moral Cause: President Woodrow Wilson framed the entry as a mission to 'make the world safe for democracy.'

• Total War:

  • The mobilization of a nation's entire resources—people, economy, and culture—for the war effort.

  • Impacts included women entering the workforce in factories and nursing, food rationing, government control of industries, and the blurring of the line between soldiers and civilians.

• The Russian Revolution ($1917$):

  • In March $1917$, Tsar Nicholas II was overthrown. In November $1917$, the Bolsheviks (communists), led by Lenin, seized power.

  • Treaty of Brest-Litovsk (March $1918$): Russia exited the war, ceding massive territories to Germany. This allowed Germany to shift its entire military focus to the Western Front, though this advantage was offset by the arrival of fresh American troops.

SECTION 6: END OF WWI

• Wilson's 14 Points (January $1918$):

  • An idealistic plan for 'peace without victory' emphasizing fairness. Key points included: Freedom of the seas, an end to secret treaties, self-determination (peoples choosing their own governments), reduction of armaments, and the creation of a League of Nations.

• Treaty of Versailles (June $1919$):

  • The official peace treaty was much harsher than Wilson's proposals and focused on punishing Germany.

  • War Guilt Clause (Article $231$): Forced Germany to accept sole blame for the war.

  • Reparations: Germany was required to pay approximately $\$33 \text{ billion}$ in damages.

  • Military Restrictions: Army reduced to $100,000$ men; no air force; limited navy.

  • Territorial Loss: Loss of Alsace-Lorraine, the Polish Corridor, and overseas colonies.

  • The League of Nations: Established as an international dispute-resolution body, though the U.S. Senate refused to join.

• Legacies of the War:

  • New Nations: The collapse of the Ottoman, Austro-Hungarian, Russian, and German empires led to the creation of Poland, Czechoslovakia, Yugoslavia, Finland, Estonia, Latvia, and Lithuania.

  • Global Unrest: Self-determination was denied to colonial peoples in Africa and Asia, leading to resentment.

  • U.S. Isolationism: Disillusioned by the war, Americans pulled back from world affairs during the $1920\text{s--}30\text{s}$.

  • Human & Economic Cost: Approximately $17\text{--}20 \text{ million}$ dead; the rise of the 'Lost Generation' (traumatized and cynical survivors); shattered economies that set the stage for the Great Depression and WWII.
