Austria felt that Serbia was overreaching its territorial boundaries and that the only way to forestall it was a preventive war. The death of Ferdinand provided a convenient excuse to go to war with Serbia. In support of Serbia, Russia mobilized its forces against Austria-Hungary, who had declared war on Serbia.
