In June 1914, Bosnian Serb student Gavrilo Princip assassinates Archduke Franz Ferdinand in Sarajevo, setting off a chain of events that lead to the outbreak of World War I. Austria-Hungary declares war on Serbia, and the local authorities begin to incite Višegrad's non-Serb population against the town's Serb residents. The bridge with the old road to Sarajevo suddenly regains its importance, as the railway line is not adequate to transport all the materiel and soldiers who are preparing to attack Serbia in the autumn of 1914. Austria-Hungary's invasion is swiftly repulsed and the Serbians advance across the Drina, prompting the Austro-Hungarians to evacuate Višegrad and destroy portions of the bridge.
