@kingledion , with respect is your question more the history of religion, rather than worldbuilding. If you want an actual example from an actual history you might be better off asking your question elsewhere. I do not think the current culture driving towards what we thing of a religion but that could change. I also think that answer would be several generations like was true for religions previously.

I am going to take this sidewasy by asking is "The free market/capitalism" a god. Certainly the "the almighty dollar" is worshipped by the cultural elite, has structures and and organized group of specially educated people to maintain the system and is part of the culture. Outside the spirit of the question but I want to point out that to get a "New God" you need a culture that will accept it and right now there is so much access to information that the need to create a new good rather than recycle and old on is limited

If this is a typical high magic D&D type world, everything changes so much that you have to define the limits of powerful characters before you postulate what kind of civilization might arise. you might consider going underground but then you have to worry about the underground menace
