World War I: Comprehensive Overview

Causes of World War I

1. Militarism:
   • Arms races among European powers, especially between Germany, Britain, and France.
   • The buildup of large standing armies and naval fleets increased tensions and readiness for war.
2. Alliances:
   • Complex alliances divided Europe into two major blocs:
     • Triple Alliance: Germany, Austria-Hungary, Italy (Italy later joined the Allies).
     • Triple Entente: France, Russia, and Britain.
   • Alliances turned regional conflicts into a global war.
3. Imperialism:
   • Competition for colonies in Africa and Asia fueled rivalries among European powers.
   • Economic and territorial disputes added to existing tensions.
4. Nationalism:
   • Intense national pride and ethnic tensions in the Balkans (e.g., Slavic nationalism).
   • The assassination of Archduke Franz Ferdinand of Austria-Hungary by a Serbian nationalist triggered the war.
5. Immediate Cause:
   • The assassination of Archduke Franz Ferdinand in Sarajevo (June 28, 1914) led Austria-Hungary to declare war on Serbia, drawing in allied powers.

Effects of World War I

1. Human and Material Losses:
   • Over 16 million deaths, including civilians and soldiers.
   • Massive destruction of infrastructure across Europe.
2. Political Changes:
   • Fall of empires: Ottoman, Austro-Hungarian, German, and Russian.
   • Formation of new nations, such as Czechoslovakia, Yugoslavia, and Poland.
3. Economic Impact:
   • War debts crippled economies, especially in Germany.
   • The Great Depression in the 1930s was partially a result of post-war economic instability.
4. Social Changes:
   • Women entered the workforce in unprecedented numbers.
   • Shift in societal attitudes toward war and leadership.
5. Global Repercussions:
   • Formation of the League of Nations to prevent future wars (though largely ineffective).
   • Rise of ideologies like communism (Russian Revolution) and fascism.

Major Movements During WWI

1. Women’s Movements:
   • Women took on roles in factories, hospitals, and offices, leading to greater calls for suffrage and equality.
   • The war accelerated women’s rights movements in countries like Britain and the United States.
2. Anti-War Movements:
   • Some groups and individuals opposed the war, such as pacifists and socialists (e.g., Eugene Debs in the U.S.).
   • War weariness led to revolutions, like the Russian Revolution in 1917.
3. Nationalist Movements:
   • In colonized regions (e.g., India, Africa), demands for independence grew as colonial subjects were drawn into the war effort.

Biggest Battles of World War I

1. Battle of the Marne (1914):
   • Stopped the German advance into France and marked the start of trench warfare.
2. Battle of Verdun (1916):
   • One of the longest battles in history, symbolizing French resistance.
