World War one was the first great war. It was the biggest war the world had seen and involved many countries.
The Great War, because it was the biggest war the world had ever seen.
THE GREAT WAR WAS WORLD WAR 1
it was war against the great countres of the world
It was initially called The Great War but when World War II broke out they changed it to World War I because they were similar wars and countries all over the world were fighting it. Another reason would be from the fact that in the first few months of the great war, everybody had believed that it would end as soon as one side had seen the formidable force of the other!
