Following tirailleurs s n galais' deployments in West Africa, Congo, Madagascar, North Africa, Syria-Lebanon, Vietnam, and Algeria from the 1880s to 1962, Militarizing Marriage historicizes how African servicemen advanced conjugal strategies with women at home and abroad. Sarah J. Zimmerman examines the evolution of women's conjugal relationships with West African colonial soldiers to show how the sexuality, gender, and exploitation of women were fundamental to the violent colonial expansion and the everyday operation of colonial rule in modern French Empire.

These conjugal behaviors became military marital traditions that normalized the intimate manifestation of colonial power in social reproduction across the empire. Soldiers' cross-colonial and interracial households formed at the intersection of race and sexuality outside the colonizer/colonized binary. Militarizing Marriage uses contemporary feminist scholarship on militarism and violence to portray how the subjugation of women was indispensable to military conquest and colonial rule.
