Causes of WWI (long-term): the Bosnian Crisis
Sovereignty and administration: Bosnia and Herzegovina had been under the sovereignty of the Ottoman Empire but administered by Austria-Hungary since the 1878 Congress of Berlin
Annexation: Austria-Hungary announced its annexation of Bosnia and Herzegovina in 1908
Reaction: Upset the fragile balance of power in the Balkans and enraged Serbia / pan-Slavic nationalists throughout Europe
Russia’s response: encouraged pro-Russian and anti-Austrian sentiment in Serbia and other Balkan provinces
Causes of WWI (long-term): Imperialism
European powers in Africa: Britain, France, and other powers held vast control over African territory, and Germany felt it was late to the game
Germany’s reaction: Germany, in response, set off the Moroccan Crisis of 1905-6 in which Kaiser Wilhelm II expressed support for Moroccan independence, deepening tensions between European powers
Causes of WWI (short-term): the assassination of Archduke Ferdinand
Who did it: a 19-year-old Bosnian Serb named Gavrilo Princip; a member of a student revolutionary group called Young Bosnia
Rationale: assassins believed that killing the Archduke would free Bosnia and Herzegovina from Austro-Hungarian rule
Hopes for Russia: they believed that Russia would then come to Serbia’s defense, defeat the Habsburg armies, and help the Bosnian Serbs gain independence
Chain of events: led to Austria-Hungary using the incident as a pretext to declare war on Serbia; Russia mobilizes to defend Serbia; Germany declares war on Russia, which draws other powers into the conflict
Causes of WWI (short-term): Austria-Hungary’s ultimatum to Serbia
The ultimatum: Austro-Hungarian government settles scores with Serbia by issuing demands that the Serbian government had to follow, under the pretext that the Serbian government was implicated in events at Sarajevo
Serbia’s response: conceded all demands made except one or two clauses. Nonetheless, Austria-Hungary declared war on Serbia
Consequences of WWI: the Armenian Genocide
Wartime security concerns: the Ottoman Empire’s participation in WWI heightened existing fears about internal security concerning the Armenian population.
The Ottoman leadership perceived Armenians as potential collaborators with the Russian enemy because of their Christian faith, proximity to the Russian front, and incidents of Armenian resistance
Radical measures: the Young Turks and the Committee of Union and Progress culminated in the decision to deport and exterminate the Armenian population to eliminate perceived threats to the empire’s stability
Consequences of WWI: Treaty of Versailles
Terms of the treaty: Germany had to
disarm
make territorial concessions
extradite alleged war criminals
agree to Kaiser Wilhelm being put on trial
pay reparations to the Entente powers
