Vladimir Propp analyzed Russian folk tales and identified that all characters can be classified into 7 types: the Hero, Villain, Donor, Princess, Helper, Dispatcher, and False Hero. Tzvetan Todorov believes that every narrative follows 5 stages - an initial state of equilibrium, a disruption to that equilibrium, the realization of the change, attempts to repair the situation, and achieving a new equilibrium. Propp focused on character types while Todorov analyzed the overall narrative structure.
