First World War (1914 -1919): Causes and Result

Four long-term causes of the First World War:


  • It means love of country and willingness to sacrifice for it.

  • Often nationalism led to rivalries and conflicts between nations.

  • The love of the country demanded the hatred of another.

  • For example, love of Germany demanded the hatred of France. Likewise the French people hated the German people.

  • In Eastern Europe narrow nationalism played a greater role. The Serbians hated Austria- Hungary.


  • Imperialism means a policy of extending economic and political control over weaker nations.

  • Colonies supplied European nations with raw materials and provided markets for manufactured goods

  • Major European countries also competed for land in Africa.


  • Militarism means a political orientation of a people or a government to maintain a strong military force and to defend or promote national interests.

  • The ‘Triple Alliance or ‘the Central Powers’, consisted of Germany, Austria-Hungary, and Italy.

  • The Balkan region was considered as “the power keg of Europe” due to competing interests in the area.

Immediate Cause

  • Austria-Hungary was already sick of Serbia and she decided to take advantage of the new situation to crush her.

  • The murder of their crown prince and his wife resulted in a demand being sent to Serbia for immediate compliance of certain terms.

  • Serbia’s reply did not pacify Austria-Hungary. Hence, Austria-Hungary backed by Germany declared war on Serbia.
