Jeffrey Rosario

PhD Candidate, American History

Trinity College, University of Cambridge


Before my PhD research at Cambridge, I completed a BA in History at Excelsior College in New York, and a Masters in History of Christianity at Yale University. I am originally from Miami, Florida, where my parents immigrated to from the Dominican Republic. I worked as a lecturer for about eight years at a non-profit organization where I taught theology and religious history for a continuing education program.

Research Interests

My current research focuses on religious dissent in America during the late nineteenth and early twentieth century. I am interested in how biblical apocalypticism informed the anti-imperialism of Protestant radicals who protested the role of mainstream churches in influencing domestic and foreign policies that undermined civil and religious liberty and propelled America to imperialistic actions abroad. This project will explore the intersections between apocalyptic belief, religion and politics, religious liberty, and American empire. I aim to shed light on the religious outsiders that are often overlooked in the standard narratives of American religious history.
