In "Wives and Husbands, " distinguished anthropologist Loretta Fowler deepens readers' understanding of the gendered dimension of cultural encounters by exploring how the Arapaho gender system affected and was affected by the encounter with Americans as government officials, troops, missionaries, and settlers moved west into Arapaho country. Fowler examines Arapaho history from 1805 to 1936 through the lens of five cohorts, groups of women and men born during different year spans. Through the life stories of individual Arapahos, she vividly illustrates the experiences and actions of each cohort during a time when Americans tried to impose gender asymmetry and to undermine the Arapahos' hierarchical age relations.
