The First World War, another name for World War I, was a major global conflict lasting from 1914 to 1918. Visualize it as a massive domino effect where one small event caused a chain reaction across Europe. It pitted the Allied Powers (France, Britain, Russia) against the Central Powers (Germany, Austria-Hungary). Trench warfare, new technologies, and immense loss of life characterized the war. It dramatically reshaped the world map and set the stage for future conflicts. Think of it as a tragic lesson in international relations.
