The history of Father Charles Edward Coughlin serves as a singular, harrowing chapter in the narrative of American democracy, religion, and mass media. Rising from the obscurity of a small suburban parish in Michigan to command a weekly radio audience of thirty million listeners, Coughlin became the first true mass-media messiah of the 20th century. His trajectory—from a progressive supporter of the New Deal to a virulent anti-Semite, fascist sympathizer, and seditionist—mirrors the turbulent anxieties of the Great Depression itself. This report offers an exhaustive analysis of Coughlin’s life, his theological and economic radicalization, the paramilitary "Christian Front" he inspired, and the complex geopolitical and ecclesiastical maneuvering required to silence him in 1942.
