The Treaty of Versailles was a peace treaty between the five nations, France, Germany, Britain, Austria-Hungary and the United States after World War I. The treaty was made in 1919, but the German government did not participate in it. In fact, Germany had the choice between signing it or facing the occupation of Germany by Allied troops. This was known as a diktat Frieden. This angered the German people as they believed that they did not start the war.
The French made the Treaty unfavorable for the Germans so that Germany would not be able to start a new war. Thus, Germany had to reduce its armed forces from 6 million to 100,000 men, and get rid of its submarines, military aircraft and most of their artillery, such as cannons. Their Navy battleships were limited to only six small ones. Germany also had to give back French territories it had occupied, as well as large territories of its own to Poland, for instance, and all of its colonies.
