And at the center of every Sumerian city-state is what's called a ziggurat. You want vocab? There's the dumb vocab, a ziggurat. Write it down like 10 times. And you can see that this kind of rectangular pyramid kind of structure, which has a temple in the middle, is really going to be, in a sense, like the religious city hall of Sumer life. But as time goes on and warfare increases, not only between city-states and outside nomadic tribes, barbarians that are fighting them, but between themselves, city-states fighting city-states, these city-states begin to have standing armies. So it's going to be the strong man that takes the front seat with the priest taking the back seat.
