The world changed because of the war. It led to the Russian Revolution, The Russian Revolution took place in 1917 when Russia's peasants and working-class people rebelled against Tsar Nicholas II's government. They were led by Vladimir Lenin and a group of revolutionaries called the Bolsheviks. The new Communist government created the Soviet Union. The war also led to the collapse of the German Empire and the collapse of the Hapsburg Monarchy, and it led to the restructuring of the political order in Europe and elsewhere, especially in the Middle East. It inevitably led to World War II and to another revolution in Germany, which brought Hitler to power. He was dedicated to the proposition of wiping away the "Stain of Versailles," which was the post- peace conference. Consciousness was also affected by the war. The war brought a lot of bitterness about the nature of war because it went on for so long and had huge casualties — for example, in a nation of 40 million the French had 1.39 million military deaths, and the British had nearly 800,000 deaths. After the war, Europeans were less eager to jump into wars. The world changed because of the war.
