Western American literature in the twentieth century has effectively mirrored life in the region. The West has for centuries seen more geographic movement, and accompanying cultural adjustment, than other American regions. These themes of movement and adjustment have dominated western writing. Literary historians’ frameworks for categorizing and analyzing this writing have emphasized a tidy process of organic development in western writing, from “frontier fiction” to more mature “regional writing,” or from frontier to regional to post- regional literature. Such models underestimate the degree to which movement and adjustment continued to shape western writing in the twentieth century and tend to separate literature produced by white Europeans from that of other cultural groups. This essay suggests that the more fluid movement and adjustment model can better illuminate the connections between ostensibly separate cultural literary streams.
