Unless the gods don't care at all about mortal political or cultural divisions.

I'm more into this. Have everyone worship the same pantheon of gods, albeit by different means and names, and leave the politics to mortals. The gods can be like (super)natural forces that mortals need to deal with in order to survive and prosper, but they don't interfere with the schemes and intrigues of people unless affected directly.
