see how he could have taken away all my dominion. I never built temples or anything but that shouldn't matter. My god was still alive also.

If you lose the last bit of your dominion you die, period.

Controlling territory does *NOT* grant you dominion! If he has half a dozen provinces with temples and you have 400 with no temples and the situation sits for long enough he will win.

Note that this works both ways, you can win by getting rid of all of his dominion. Sometimes it's the easiest way to take out a capital full of powerful troops.
