Causes of World War I

Alliance Systems

  • Triple Entente and Triple Alliance: European nations formed alliances for mutual defense and territorial expansion. The Triple Entente included France, Russia, and Britain, while the Triple Alliance consisted of Germany, Austria-Hungary, and Italy (later joined by the Ottoman Empire).

Nationalism and Imperialism

  • Nationalist Tensions: Rising nationalism fueled territorial disputes and competition among European powers, particularly in the Balkans.

  • June 28, 1914: Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was assassinated in Sarajevo by a Bosnian Serb nationalist. This event triggered a chain reaction of alliances and ultimatums among European powers.

Major Events and Campaigns

Western Front

  • Trench Warfare: Both sides dug extensive trench systems from the Swiss border to the North Sea, resulting in brutal stalemate and trench warfare.
