No, there have been many wars prior to World War I.
World War I was the first war in which the majority of the countries and people in the world were involved.
The first recorded war is believed to be between Sumer(Iraq today) and Elam(part of what is now Iran). This war occurred around 2700 B.C.E. There were likely many wars and great conflicts prior to this, but the first instances of writing occurred not long before this time, so there is not much recorded prior.
WW1 is short for Wold War 1. It was the first war that truly impacted all the countries of the world.
