It was, at the time, called the Great War. There were many countries involved and there was conflict not only in Europe, but, to a lesser extent, in Asia & Africa. And there was confict at sea as well, the Falkland Islands in the South Atlantic was a battle which saw the destruction of Graf Spees raiding. (That's the WW1 Admiral, not the WW2 warship) for example. In previous times Wars had been a series of battles involving conflict, generally, on a far smaller scale, and with far fewer protagonists. WW1 is extensive in scale, only then to be dwarfed by the conflict between 1939 & 1945 which was WW2.
The war that was fought from 1914-1919 was called the Great War or the World War during and after the fighting. It was a global, i.e. worldwide, military conflict that involved most of the world's great powers and many lesser powers.
It was not called World War 1 until the wars that began in 1939 in Europe and earlier in Asia came to be seen as a single global conflict. Then the two had to be distinguished so the 1914 war was called World War 1 and the war that ended in 1945 was called World War 2 in the English Speaking world.
