. What was the immediate cause of the First World War

Best Answer


  • The First World War began in 1914 and lasted until 1918. 
  • It lasted roughly four years and was blamed for tremendous destruction and deaths. 
  • World War I is often regarded as one of the most significant conflicts in history.
  • The Balkans were the starting point for World War I. There were 17 million deaths and 220 million injuries. 
  • Austria-rivalry Hungary's with Britain, France, and, later, the United States. Scholars tend to explain the causes of the First World War in many ways, with the July Crisis or the Sarajevo Crisis being the most recent. 
  • The July Crisis was a period of international emergency when Gavrilo Princip, a member of the Serbian nationalist terrorist group known as the Black Hand, assassinated Archduke Franz Ferdinand of Austria-Hungary and his wife in Sarajevo, Bosnia and Herzegovina, which was then a part of Austria-Hungary. Before World War I, the following defence agreements were made:
  • Serbia and Russia
  • Austria-Hungary and Germany
  • France and Russia 
  • Britain, France, and Belgium
  • Japan and the United Kingdom
  • Protests erupted because Austria had complete control over the region. 
  • Serbia sought to take control of Bosnia and Herzegovina. 
  • As a result of this occurrence, Austria-Hungary declared war on Serbia. 
  • Russia began mobilising its military after forming an alliance with Serbia. 
  • As a result of this, Germany launched an attack on Russia. 
  • As a result, the battle spread around the globe.

Final Answer:

(i) The Sarajevo incident was the direct cause of World War One. The Austrian Archduke Francis Ferdinand and his wife were shot dead in Sarajevo, Bosnia's capital, on June 28, 1914.

(ii) Austria suspected Serbia of being behind the Prince's assassination and issued an ultimatum to Serbia. Serbia declined to accept the requests because of Russia's support. Austria declared war on Serbia as a result.
