At the end of the First World War, the unconditional surrender of Germany in front of the Allied Nations, brought an end to the war. Then the Allied Nations undertook the "Peace Process" in Paris, in 1919 in which some 58 commissions were formed and 145 sessions were organised. The agreement made with Germany during the Paris Peace Process, was made in the Mirror Palace at Versailles. Thus, it come to be known as the 'Versailles Treaty'.
