World History – 1400 to Present Unit 11 Review: The War to End All Wars

Key Players and Alliances

• The Triple Alliance formed in 1882 consisting of Germany, Austria-Hungary, and Italy as a defensive pact against France and Russia
• The Triple Entente formed in 1907 as an alliance between France, Russia, and Great Britain to counter the Triple Alliance
• Germany's Kaiser Wilhelm II's aggressive foreign policy and naval buildup contributed to rising tensions in Europe
• Austria-Hungary's Archduke Franz Ferdinand's assassination by Serbian nationalist Gavrilo Princip on June 28, 1914, triggered the war
  • Serbia had close ties with Russia, which pledged support against Austria-Hungary
• The Ottoman Empire joined the Central Powers (Germany and Austria-Hungary) in October 1914
• Italy, despite being part of the Triple Alliance, remained neutral until joining the Allies (Triple Entente) in 1915
• The United States entered the war on the side of the Allies in April 1917 after Germany's unrestricted submarine warfare

Causes and Buildup

• Nationalism fueled tensions as countries sought to assert their power and influence on the global stage
• Imperialism led to competition for colonies and resources, particularly in Africa and Asia, among European powers
• Militarism resulted in an arms race and the buildup of standing armies across Europe
  • Germany's military expansion, particularly its naval buildup, threatened British naval supremacy
• The system of alliances divided Europe into two opposing camps (Triple Alliance and Triple Entente), increasing the risk of a larger conflict
• The Balkans, a region of ethnic and political instability, became a powder keg due to the decline of the Ottoman Empire and the rise of Slavic nationalism
  • Austria-Hungary's annexation of Bosnia and Herzegovina in 1908 heightened tensions with Serbia and Russia
• The July Crisis, a series of diplomatic maneuvers and ultimatums following the assassination of Archduke Franz Ferdinand, escalated tensions and led to the outbreak of war

Major Battles and Campaigns

• The Western Front saw trench warfare and battles of attrition, such as the Battle of Verdun (1916) and the Battle of the Somme (1916)
  • The First Battle of the Marne (1914) halted Germany's initial advance into France
  • The Battle of Passchendaele (1917) resulted in heavy casualties and limited gains for the Allies
• The Eastern Front saw large-scale battles between Germany, Austria-Hungary, and Russia, such as the Battle of Tannenberg (1914) and the Brusilov Offensive (1916)
• The Gallipoli Campaign (1915-1916) was a failed Allied attempt to capture the Dardanelles Strait and knock the Ottoman Empire out of the war
• The Battle of Jutland (1916), the largest naval battle of the war, ended in a tactical victory for Germany but a strategic victory for Britain
• The Middle East saw campaigns against the Ottoman Empire, including the Arab Revolt (1916-1918) and the Battle of Megiddo (1918)
• The Italian Front witnessed battles between Italy and Austria-Hungary in the Alps and along the Isonzo River
• The Hundred Days Offensive (1918) was a series of Allied victories that ultimately led to Germany's defeat and the end of the war

Technological Advancements

• Machine guns revolutionized infantry combat, making frontal assaults more costly and contributing to the stalemate of trench warfare
• Artillery, particularly heavy artillery and howitzers, played a crucial role in bombarding enemy trenches and positions
• Poison gas, first used by Germany at the Second Battle of Ypres (1915), introduced chemical warfare to the battlefield
  • Various types of gas were used, including chlorine, phosgene, and mustard gas
• Tanks, first employed by the British at the Battle of the Somme (1916), provided a means to break the deadlock of trench warfare
• Aircraft evolved from reconnaissance tools to fighters and bombers, engaging in aerial combat and strategic bombing
  • The Fokker Scourge (1915-1916) saw German fighters temporarily dominate the skies
• Submarines, particularly Germany's U-boats, waged unrestricted warfare against Allied shipping, leading to the sinking of the Lusitania (1915)
• Advances in medical technology, such as the use of X-rays and the development of the Thomas splint, improved the treatment of wounded soldiers

Home Front and Civilian Impact

• Governments implemented rationing and price controls to manage shortages and ensure the fair distribution of resources
• Women entered the workforce in unprecedented numbers to replace men who had gone to war, taking on roles in factories, agriculture, and the service sector
  • Women's contributions challenged traditional gender roles and paved the way for suffrage movements
• Propaganda campaigns aimed to boost morale, encourage enlistment, and demonize the enemy
  • Posters, films, and songs were used to shape public opinion and garner support for the war effort
• Civilians faced hardships such as food shortages, inflation, and the loss of loved ones
• The influenza pandemic of 1918-1919, known as the Spanish Flu, claimed millions of lives worldwide, exacerbated by the movement of troops and wartime conditions
• The Russian Revolution of 1917 led to Russia's withdrawal from the war and the establishment of the Soviet Union
  • The Bolsheviks, led by Vladimir Lenin, seized power and signed the Treaty of Brest-Litovsk with Germany in 1918

Turning Points and Decisive Moments

• The First Battle of the Marne (1914) halted Germany's Schlieffen Plan and led to the stalemate of trench warfare on the Western Front
• The sinking of the Lusitania (1915) and Germany's unrestricted submarine warfare strained US-German relations and contributed to the US entry into the war
• The Battle of Verdun (1916) symbolized the brutality and futility of trench warfare, with heavy casualties on both sides
• The Brusilov Offensive (1916) was Russia's most successful offensive, but it ultimately weakened the Russian army and contributed to the Russian Revolution
• The Battle of the Somme (1916) saw the first use of tanks and the horrific casualties associated with trench warfare
• The entry of the United States into the war in 1917 provided a significant boost to the Allied war effort in terms of manpower and resources

• The Treaty of Trianon (1920) further dismantled the Austro-Hungarian Empire, with Hungary losing significant territory to neighboring countries
• The Treaty of Sèvres (1920) partitioned the Ottoman Empire, but it was later superseded by the Treaty of Lausanne (1923) following the Turkish War of Independence
• The League of Nations was established to promote international cooperation and prevent future wars, but it ultimately failed to maintain peace
• The war left millions dead, empires dissolved, and economies devastated, setting the stage for the rise of totalitarian regimes and future conflicts

Legacy and Historical Significance
