World War I ended in the year 1918. The war, which began in 1914, involved major world powers and was primarily fought in Europe. It resulted in unprecedented destruction and loss of life. The conflict concluded with the signing of the Armistice of Compiègne on November 11, 1918. This armistice signaled the cessation of hostilities on the Western Front, effectively ending the war. The following year, in 1919, the Treaty of Versailles was signed, formally ending the state of war between Germany and the Allied Powers. World War I had a profound impact on global politics, redrawing boundaries, and setting the stage for future conflicts.
