A narrative is a story that describes a sequence of fictional or non-fictional events. There are different types of narratives such as linear and non-linear narratives. Examples of non-linear narratives include The Social Network and 500 Days of Summer. Theories of narrative include structuralist Tzvetan Todorov who analyzed how narratives establish equilibrium, face disruption, and restore order. Claude Levi-Strauss viewed narrative through binary oppositions like good and evil. Vladimir Propp identified character roles and narrative functions that can be applied across different stories.
