Admittedly I don't know much about feudal Japan in general, but I was reading about these guys - a populist/peasant rebellion based in religion that seemed to go pretty strong for a while.
So my question is about the Ikko-Ikki, and their particular sect of Buddhism in general.
What would it have taken for this revolution to gain more strength? What was the maximum extent it could have reached? What major changes could it have lead to?
