The end of World War 1 is often considered to be in 1918 when the Armistice was signed on November 11th, bringing an end to the fighting. However, some argue that the war officially ended in 1919 with the signing of the Treaty of Versailles, which formally ended the state of war between Germany and the Allied Powers.
Others may argue that the war did not truly end until 1921 with the signing of the Treaty of Berlin, which officially ended the state of war between Germany and some of the Allied Powers.
This shows that even simple details, like the end date of a war, can appear different depending on the context and perspective of the person interpreting the events.
