2 Background Causes of World War I Alliances Nationalism Imperialism Militarism

3 Alliances An agreement between between countries to come to each other’s aid in case of war. Two major alliances: Triple Alliance: Germany, Austria-Hungary, Italy (does not enter war on this side, replaced with Ottoman Empire) Triple Entente: France, Russia, and Great Britain If one nation was pulled in war, all would enter

4 Nationalism Extreme loyalty to a nation and concern for its welfare Multi-ethic empires (Austria-Hungary and the Ottoman Empire) had many groups seeking independence Balkans are ready to explode (“powder keg of Europe, Balkan Peninsula)—Serbia and Bosnia in Balkans

5 Imperialism A nation’s attempt to gain control of a weaker nation Nations wanted control to gain raw materials, Europe had divided Africa in 1884

6 Militarism A nation’s policy to maintain strong armed forced Britain and Germany competed for the strongest navy Militarism included complex plans in case war broke out

7 Immediate Cause: Assassination of Archduke Ferdinand of Austria-Hungary (heir to the throne) Shot by a Serbian nationalist in Bosnia, part of Austria- Hungary (A.H.)

8 Assassination is considered the “spark” of the war A.H. blamed Serbia and Germany gave A.H. a “blank check” saying they would back them no matter what A.H. then gave Serbia an “ultimatum” saying they must agree to all their demands or they would declare war—A.H. declared war anyway Russia then mobilized in case of war— Germany then declares war on Russia and France

9 Germany then invaded Belgium in order to get to France. Britain then declares war on Germany as Belgium was neutral.

Germany apologized.
