The Great War Why Did It Happen?

LONG TERM FACTORS Militarism Buildup of forces Large standing armies Naval race between Britain & Germany New technologies

Alliances Secret treaties between nations Triple Alliance/ Central Powers - Germany - Austria-Hungary - Italy * Triple Entente/ Allied Powers - France - Russia - Great Britain - United States in 1917

Nationalism Internal Conflict – Disputes over territory * Germany & France – over Alsace Lorraine * Balkans/Slavic peoples wanting independence

Imperialism Over natural resources/markets in Asia & Africa * France v. Germany over Morocco * Russia v. Japan over Manchuria/Korea

IMMEDIATE FACTORS Austria-Hungary governs over Bosnia & Herzegovina Upsets Serbia Serbia is allied to Russia (seen as the protector of the Slavs) - Similar ethnic heritage

Assassination Austrian Archduke Franz Ferdinand (heir to throne) and wife Sophie visit Sarajevo (capital of Bosnia) Black Hand – Serbian nationalist/terrorist group Gavrilo Princip – assassinates Ferdinand & Sophie

Reaction! A-H believes Serbia plotted the murder – Gives ultimatum – final set of demands Serbia must… Crack down on anti-Austrian groups Dismiss nationalistic government officials ***Let Austria investigate in Serbia***

Austria-Hungary declares war on Serbia Russia/Tsar Nicholas II begins to mobilize army Germany declares war on France (Russia’s ally) After Germany invades Belgium, Great Britain declares war on Germany, etc., etc., etc.,

Could war have been avoided?

Germany’s immediate plan of action Schlieffen Plan Attack France through Belgium to sack Paris -Move quickly before Russia can mobilize -Avoid fighting a two-front war

The First World War: Why? Long term - 1. Militarism 2. Alliance System 3. Nationalism 3. Imperialist Competition Short term – Assassination of Franz Ferdinand of the Austro- Hungarian Empire Franz Ferdinand, Archduke of Austria and his Wife Sophie, Duchess of Hohenberg one hour before their deaths, June 28, 1914

The First World War:

Why did it take so long for America to get involved in the war? America was isolationist “Why should I get involved in someone else’s problems”

Thinking Slide: Is isolationism really an option for a country as powerful as the United States?

Which side should the US pick? 11 million German-Americans Irish-Americans hated Great Britain Close cultural ties Shared transatlantic cables (so censored stories) Big business loaned much $ to allies Central Powers: Allies: US Exports to both sides:

What did it take to get the US involved? Britain blockaded (stopped) all German ships going to America Germany announced a submarine war around Britain Y-53 German Submarine 1916

What did it take to get the US involved? Lusitania torpedoed, sinking with 1200 passengers and crew (including 128 Americans) Was eventually found to be carrying 4200 cases of ammunition German Propaganda Justifying Lusitania sinking

What did it take to get the US involved? The US sharply criticized Germany for their action Germany agreed not to sink passenger ships without warning in the future Note in Bottle After Lusitania Disaster

What did it take to get the US involved? Zimmerman Note US intercepted a note from Germany to Mexico, It promised Texas, New Mexico, and Arizona back in return for an alliance

What did it take to get the US involved? Zimmerman Note + the sinking of 4 unarmed American ships led to a declaration of war

How was the war looking for the allies? Russia left the war after its communist revolution in 1917 Made it a one front war for Germany - all its troops could concentrate on France Not Good...

Convincing the American People Posters - Gee!! How do you think this poster helped to convince the American people that the war was a good idea?

Convincing the American People 1. War to End All Wars Idealism: 2 Goals For War : 2. Making the World Safe for Democracy

Convincing the American People Idealism: Fourteen Points What? President Wilson’s Plan for after the war Fourteen promises, including freedom of the seas & a League of Nations to work for peace President Woodrow Wilson

What did the US do to help? Convoy system helped to provided food and money Selective Service Act – provided fresh troops needed to win the war Shipyard workers “exempt” American Troops March Through London Supplies:

The Armed Forces Selective Service Act (1917) draft: 2.8 million draftees, 2.9 million volunteers Eventually 2 million were sent to Europe African Americans - 400,000 served, few officers; served in segregated units (369 th Infantry, one example) African Americans hoped service abroad = equal rights at home (not so)
