 What is a narrative? Most generally, it is an account of how and why a situation or event came to be. A narrative is intended to provide an account of how a complex historical event unfolded and why. We want to understand the event in time. What were the contextual features that were relevant to the outcome—the conditions at one or more points in time that played a role? What were the actions and choices that agents performed, and why did they take these actions rather than other possible choices? What causal processes—either social or natural—may have played a role in influencing the outcome? So a narrative seeks to provide hermeneutic understanding of the outcome—why did actors behave as they did in bringing about the outcome?—and causal explanation—what social and natural processes were acting behind the backs of the actors in bringing about the outcome? And different narratives represent different mixes of hermeneutic and causal factors. A crucial and unavoidable feature of narrative history is the fact of selectivity. The narrative historian is forced to make choices and selections at every stage: between "significant" and "insignificant", between "sideshow" and "main event", and between levels of description.
