The war to end war was a World War that was fought during the early 1900s. It was a very long and violent conflict that involved many different countries. The main goal of this war was to put an end to all wars, and the people who fought it hoped that it would be the last one. It was fought mainly in Europe, but some other countries were also involved. The war lasted for four years, and millions of people lost their lives. Despite the terrible losses, the war ended with the victory of the Allied Forces, who consisted of the countries that wanted to end the war. This victory meant that there would no longer be war in Europe, and many people around the world were very relieved.
