Basically what it says on the tin: Let's say that for some reason King Ferdinand either never establishes the Pragmatic Succession decree in Spain, or reputed it before his death. Maybe he has a fallout with the like regent candidates for his daughter, or his priests convince him it's God's plan. Whatever the case, his brother the Infanta Carlos ascends to the Spanish throne following his death, peacefully and with great legitimacy bringing his conservative faction into power at court. How would this diverts development of the Spanish Empire from our timeline?
