Jeffrey Rosario

PhD Candidate in American History

I am originally from Miami, Florida, where my mother settled after immigrating from the Dominican Republic. Before my PhD research at Cambridge, I completed a Masters in History of Christianity at Yale University. Prior to my studies at Yale 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.




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 domestic and foreign policies that undermined civil and religious liberty and propelled the United States 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.
