The two sides of the war consisted of the Allied Powers that was formed by France, Great Britain, Russia, the United States and the Central Powers, which consisted of Germany, Austria-Hungary, and Ottoman Empire.
Germany was one of the primary countries that was involved on the World War I because before everything began Germany made a plan named “The Schlieffen Plan” that was against France, but France and Germany were at Belgium that was a neutral allied and have their first battle. After this Great Britain declared war to Germany because they violate the neutrality of Belgium.
The Germans, in order to prevent England from entering the war, tried to make it appear as if Russia had really started the war. They announced that any conflict between Austria and Serbia was a local conflict in which outside powers should not interfere. Of course, the other European states saw right through this ruse and prepared themselves for a war that would involve all of the great powers.
The war began on August 3rd when Germany declared war on France, saying that they had infringed upon Germany's territory. The German army that took the field August 1914 has been described as the most brilliant the world had ever seen. The day after the declaration of war against France, Germany moved soldiers into Belgium, and the Belgians resisted. Three days later the Germans captured the stronghold of Liege, and Belgium fell. By the end of the initial offensive, August 25th, Germany's front was uncontested by any of the other powers. The Schlieffen plan had stated that the German army should have been in France in 40 days and by the 32nd day the Germans were still 25 miles from the city.
A short war was basically what the entire German military was counting on as the only way to win the war. When this possibility was taken away, the prospect of winning began to fade. Moltke's lack of judgment in this matter can be attributed to the distance he was away from the actual line of battle. He could not make decisions because he could not see what was going on. The situation at the beginning of 1915 was definitely not in Germany's favour. The western front showed 90 German divisions against 108.5 Allied. On the eastern front, there were 78.5 German divisions against 93.5 Russian. The armistice was given to Germany. It basically required that the Germans retreat into their own borders and leave all of their weapons behind.
William fled the country and Prince Max was put on the throne just long enough to sign the armistice. The German soldiers began to retreat into their own country and on November 11 the armistice was signed, officially ending the war.
