20th Century, 1914: June 28, 1914, the Archduke Franz Ferdinand, the heir to the throne of Austria-Hungary, was assassinated by Gavrilo Princip, a Yugoslav nationalist. This incident quickly escalated into one of the bloodiest conflicts in human history. The Great War, or World War I, saw the rise of revolutions and the death of 9 million soldiers and 7 million civilians. The philosophy, technology and geography of the world were forever altered. The world of music was also affected as composers served in battle and sought to express their patriotism and also the true human cost of the conflict.
