1917 it turned against the government. Russian propaganda In order for the Russians to legitimize their war efforts, the government constructed an image of the enemy through state-instituted propaganda. Their main aim was to help overcome the legend of the "invincible" German war machine, in order to boost the morale of civilians and soldiers. Russian propaganda often took the form of showing the Germans as a civilized nation, with barbaric "inhuman" traits. Russian propaganda also exploited the image of the Russian POWs who were in the German camps, again in order to boost the morale of their troops, serving as encouragement to defeat the enemy and to get their fellow soldiers out of German POW camps that were perceived as inhumane.

However, the "spark" that ignited the First World War is attributed to the assassination of Archduke Franz Ferdinand by Gavrilo Princip, which took place on 28 June 1914. Approximately a month later, on 28 July 1914, Austria-Hungary declared war on Serbia. This act led to a series of events that would quickly expand into the First World War; thus, the Habsburg government in Vienna initiated the pivotal decision that would begin the conflict. The causes of the Great War have generally been defined in diplomatic terms, but certain deep-seated issues in Austria-Hungary undoubtedly contributed to the beginnings of the First World War. The Austro-Hungarian situation in the Balkans pre-1914 is a primary factor in its involvement in the war. The movement towards South Slav unity was a major problem for the Habsburg Empire, which
