I'm very curious to learn about the origins of RP and RPW theory. When and how did it become a "movement"/clear theory? Who established it? I understand that it's based on objective truths that you could say are timeless, but that's not really the answer I'm after. I've looked through the wiki and there doesn't seem to be any info on where this all came from.

Do any of you out there know? Or can point me to resources that go onto it?
