Welcome!Today we'll explore the causes of World War One, a key topic in Paper 1 Section B: Conflict and Tension, 1894–1918. We'll break it down step by step and help you understand the events that led to the outbreak of war.
What caused World War One?World War One began in 1914 and was caused by a combination of long-term and short-term factors. These include militarism, alliances, imperialism, and nationalism. We will also look at the assassination of Archduke Franz Ferdinand, which acted as the immediate trigger for the war.
MilitarismMilitarism is when countries build up their armed forces and military power. Before World War One, European powers like Germany and Britain competed to have the strongest armies and navies, increasing tensions.

AlliancesCountries formed alliances to protect themselves. These were agreements between nations to support each other in case of war. By 1914, two main alliances existed: the Triple Alliance (Germany, Austria-Hungary, and Italy) and the Triple Entente (Britain, France, and Russia). Alliances increased the risk of war because if one country was attacked, its allies had to get involved.

Nationalism also led to demands for independence from groups like the Serbs in Austria-Hungary.
