Alien Conquistadors
Basically I'm looking for media where the world is invaded by aliens who want to Civilize humanity. They tell us they're here to save our souls, but what that winds up meaning is slave labor, forced conversions, torture, and executions. Bonus points if it covers Earth's later status as a colony to Space-Spain, and more bonus points if this is all tied to the Space-Doctrine of Discovery uniting Space-Europe under the Space-Pope
I know there have to be a few popular stories out there with premises like this, but I can't think of any, and I'd like to try some
You're going to hate me for suggesting this, but isn't this essentially what is happening in Signs?
I haven't seen it in a very long time but I think the subtext and some comments from Shyamalan suggest that signs was a supernatural, religious event that most people interpretted as aliens. I can't remember the details though.
it's also been a very long time since I last saw it, but I could've swore that there was a literal scene showing in plain and clear view, the alien spaceships packing up and leaving after Mel Gibson realized that water killed them?
