Answer: The assassination of Arch Duke Francis Ferdinand
Notes: The immediate cause was the assassination of Arch Duke Francis Ferdinand who was heir to the Austrian throne. Arch Duke Francis Ferdinand and his wife were assassinated by Serbians in the Bosnian capital Sarajevo when they paid a visit to this city on 28th June 1914. The news of this murder shocked many countries. 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 an ultimatum 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. Russia mobilised her forces in favour of Serbia.
