In Word Across the Water, Tom Smith brings the histories of Hawai'i and the Philippines together to argue that US imperial ambitions towards these Pacific archipelagos were deeply intertwined with the work of American Protestant missionaries. As self-styled interpreters of history, missionaries produced narratives to stoke interest in their cause, locating US imperial interventions and their own evangelistic projects within divinely ordained historical trajectories. As missionaries worked in the shadow of their nation's empire, however, their religiously inflected historical narratives came to serve an alternative purpose. They emerged as a way for missionaries to negotiate their own status between the imperial and the local and to come to terms with the diverse spaces, peoples, and traditions of historical narration that they encountered across different island groups. Word Across the Water encourages scholars of empire and religion alike to acknowledge both the pernicious nature of imperial claims over oceanic space underpinned by religious and historical arguments, and the fragility of those claims on the ground.
