Why were World War 1 and World War 2 seen as a World Wars, yet the 7 Years War wasn’t seen as one?

Question

I’ve always wondered this. The 7 Years war was fought on multiple continents and decided the world as we know it, just like both World Wars. I just don’t get why it wasn’t seen as a world war and I came here to ask why.

Answer 1

The 30 years war also could qualify (as a stretch). Not only did it drag in many European powers that had very little reason to get involved. But some of those powers were fighting outside Europe (mostly the Spanish).
