Updated: Aug 7

The assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian empire led to the immediate outbreak of war among several nations in Europe which then turned into a Great World War.

  • Serbian nationalists wanted to end the Austro-Hungarian rule over the Balkan(mainly in Serbia, Bosnia, Herzegovina) region.

  • Archduke visited Bosnia on a military inspection tour. Serbians used this opportunity and killed Franz Ferdinand and his wife.

  • Austria confirmed to declare war on Serbia after consulting help from Germany to prevent Russian intervention.

  • Russian entered the war with France as they were allies to Serbia.

  • The dual monarchy of Austria-Hungary sent their final demands to Serbia in harsh terms which made Serbia impossible to accept. This gives an yellow signal to both military troops to get ready for war.

  • Germany sent its troops to Luxembourg and invaded Belgium demanding a free passage into France to declare war.

  • Great Britain which had no concern about the on-going war declared war on Germany to defend Belgium.

  • Peace between the European nations quickly collapsed and within a week Serbia, Russia, France, Belgium, Great Britain had lined up against Austria-Hungary and Germany. World War I had begun!

  • The outbreak of war in August 1914 was actually greeted with celebration and confidence by the people of Europe. Most welcomed the war with a patriotic feeling wishing their own country to be victorious anyway. Only few feared about the disastrous consequences and monstrous deaths the war going to bring.
