What I'm trying to say, is the Shiism rejected the Caliphs authority, and hence came with an early concept that unjust rulers and rulers with no sanction from God, have no authority. Sunnism on the other hand catered the needs of the rulers, and hence interpreted hadiths about successors, 12 successors, and ulil-Amr in Quran, to be referring to what people took as power.
The Shias wanting divine justice, believed, that God never sanction submission to authorities while more knowledgeable, just, wise, and pious humans existed who virtues were manifested by God.
