Question

How did the Sarajevo Crisis in 1914 lead to the First World War?

Answer 1

Sarajevo crisis: On June 28, 1914 Archduke Ferdinand along his wife Sophia were assassinated by a student of the ‘Black hand’, a revolutionary organisation, at Sarajevo, the Capital of Serbia.

Austria served an ultimatum on Serbia on July 23 making eleven demands. Serbia accepted most of the demands except those that would have led to the loss of her sovereignty. Austria declared war on Serbia on 28th July 1914. This was the immediate cause of the Fist World War.
