<P> The newly formed Russian Republic continued to fight the war alongside Romania and the rest of the Entente until it was overthrown by the Bolsheviks in October 1917 . Kerensky oversaw the July Offensive, which was largely a failure and caused a collapse in the Russian Army . The new government established by the Bolsheviks signed the Treaty of Brest - Litovsk with the Central Powers, taking it out of the war and making large territorial concessions . Romania was also forced to surrender and signed a similar treaty, though both of the treaties were nullified with the surrender of the Central Powers in November 1918 . </P> <P> The front in the east was much longer than that in the west . The theater of war was roughly delimited by the Baltic Sea in the west and Minsk in the east, and Saint Petersburg in the north and the Black Sea in the south, a distance of more than 1,600 kilometres (990 mi). This had a drastic effect on the nature of the warfare . </P> <P> While World War I on the Western Front developed into trench warfare, the battle lines on the Eastern Front were much more fluid and trenches never truly developed . This was because the greater length of the front ensured that the density of soldiers in the line was lower so the line was easier to break . Once broken, the sparse communication networks made it difficult for the defender to rush reinforcements to the rupture in the line, mounting rapid counteroffensives to seal off any breakthrough . </P> <P> Propaganda was a key component of the culture of World War I. It was most commonly deployed through the state - controlled media to glorify the homeland and demonize the enemy . Propaganda often took the form of images which portrayed stereotypes from folklore about the enemy or from glorified moments from the nation's history . On the Eastern Front, propaganda took many forms such as opera, film, spy fiction, theater, spectacle, war novels and graphic art . Across the Eastern Front the amount of propaganda used in each country varied from state to state . Propaganda took many forms within each country and was distributed by many different groups . Most commonly the state produced propaganda, but other groups, such as anti-war organizations, also generated propaganda . </P>
