Today it seems common to refer to both World Wars with the terms "World War 1" and "World War 2" pretty much everywhere. (in the respective translation of course)
But I recently realized that this kind of notation only makes sense when there is more than one WW to refer to. Surely WW1 was not used before WW2, as nobody was hoping for another event like this.
What was the common name for WW1 during the war and in the period before WW2? If there were different names used by the different parties, what were they?
