The Armistice of 1918 was an agreement that marked the end of fighting in World War I. It was signed on November 11, 1918, between the Allies and the Central Powers, effectively ceasing hostilities on the Western Front. This agreement laid the groundwork for the eventual peace negotiations that would follow. The armistice was significant as it ended four years of brutal warfare, resulting in millions of casualties. It also led to the collapse of empires, including the Austro-Hungarian Empire and the Ottoman Empire, and set the stage for the signing of the Treaty of Versailles in 1919.
