Answer:
The Great War
Explanation:
Other names for World War 1 include 'The War to End All Wars', The War of the Nations, WW1 and 'The Great War'.
The great war
When the war first happened it was called the great war since (I am pretty sure) it was the first of it's kind but it was changed to World War 1 (WW1) when WW2 happened.
Hope this helps :)
