In short
On October 5, 1908, Austria-Hungary formally annexed Bosnia and Herzegovina, territories it had occupied but not officially owned since 1878. The move enraged Serbia and Russia, destabilized the Ottoman Empire further, and set the Balkans on a collision course that would eventually trigger World War I.
