Why is it useful for historians to craft historical narratives

Narrative history is writing history as a story that focuses on the chronological order of history.

There are several reasons why It is useful for historians to craft historical narrative.

1. The event in time can be better understood.

2. The key roles and relevant features can be easily point out.  

3. The actions can be easily described.And why those rather than other actions were taken.

4. What causal processes(social or natural) may have played a role in bringing the world to the outcome of interest?

It is useful because the craft of historical narratives make possible to see that many histories, including quantitative ones, were narratives that achieved their persuasive effects in part because they were narratives. Many features of historical interpretation could be understood as properties of narratives. The choice of central subject, the decision as to when to begin and when to end the story, the characterization of the principal actors, the drawing out of moral import, and the identification of turning points are all activities that both historians and novelists perform.
