Causes of World War One

  • The immediate cause of the Great War was the assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian throne.

  • Gavrilo Princip: The killer of Archduke Franz Ferdinand and member of the black hand terrorist group.

  • The Black Hand: Nationalist and terrorist organization devoted to ending Austro-Hungarian presence in the Balkans.

  • After Archduke Franz Ferdinand’s assignation,

    • Austria-Hungary demanded an end to anti-Austrian agitation in Serbia.

    • Serbia declined the ultimatum, leading Austria-Hungary to declare war on Serbia on July 28th 1914.

Long Term Causes

    • Alliances: Tensions with a common country caused some to join together as allies, promising to protect an ally if they were attacked. This made the initial war between Serbia and Austria-Hungary go global quick.

    • Imperialism: Once all avaliable land to colonize was claimed, European powers began to fight each other over land, making bitter rivals join alliances with shared rival countries.

    • Nationalism: Multinational empires had multiple nationalist movements within their subjects, creating ethnic tensions.
