In this unique study, Ethan R. Yorgason examines the Mormon "culture region" of the American West, which in the late nineteenth century was characterized by sexual immorality, communalism, and anti-Americanism but is now marked by social conservatism. Foregrounding the concept of region, Yorgason traces the conformist-conservative trajectory that arose from intense moral and ideological clashes between Mormons and non-Mormons from 1880 to 1920. Looking through the lenses of regional geography, history, and cultural studies, Yorgason investigates shifting moral orders relating to gender authority, economic responsibility, and national loyalty, community, and home life. Transformation of the Mormon Culture Region charts how Mormons and non-Mormons resolved their cultural contradictions over time by a progressive narrowing of the range of moral positions on gender (in favor of Victorian gender relations), the economy (in favor of individual economics), and the nation (identifying with national power and might). Mormons and non-Mormons together constructed a regime of effective coexistence while retaining regional distinctiveness.

After an introduction about basic beliefs and two chapters that briefly recount the church's history, three chapters discuss Mormons in American culture, society, and politics.

Huge mountain ranges and vast uninhabited areas characterize the Mountain West. The region is home to several dense urban centers, but there is enough space between cities for three very distinct religious cultures to develop. Arizona and New Mexico's religious public life is still dominated by the Catholic church which was in place three centuries before these areas became U.S. states. Mormons came to Utah and Idaho in the 19th century to set up their own church-state and only later were admitted to the Union. Religious minorities from Native Americans to 'mainstream' Protestants must contend with these religious establishments. In the third subregion of Colorado, Wyoming, and Montana no one religious body dominates and many inhabitants claim no religious affiliation at all. Religion and Public Life in the Mountain West explores these three distinct religious regions but then goes on to see how they work together and what they have in common.
