<br>The First World War was expected to be short, with a quick triumph on either side. On the contrary, the war caused a giant massacre to all the countries involved, and lasted for four years. Also against the expectations of political leaders and military commanders new techniques of fighting were used, as well as new weapons (for example the chloric gas, tanks and aircraft
). Due to all this, 13 million people were killed, of which 2 million were Germans, 1.75 million Russians, 1.5 million Frenchmen, 1 million British and 0.5 million Italians. But death was just one of the worst consequences of the First World War. Just military failures on the fronts, along with other problems directly affected internal politics in a great way. This horrible catastrophe also left most of the countries in huge debts, especially Germany, Austria, Hungary, Russia, and many others. This led to poverty and chaos, and the people were suffering. That is why they started to revolt, but the political system was so exhausted after the war that it didn 't do anything to solve this.

<br>The effects of the war sped up the changes. It is an arguable fact, whether the war also had a liberating effect. If it did, it was greatly affected by the downfall of three empires, the Austro-Hungarian Empire, Tsarist Russia and Keiser 's Germany. In Russia the tsar abdicated and was replaced by the Provisional Government, but it only took 8 months and Russia moved from autocracy to communism.
