Charles R. Gallagher reconstructs the history of the Christian Front, an American fascist organization that in the late 1930s plotted to overthrow the government, assassinate members of Congress, and establish a Nazi-style regime with the blessing of the Catholic Church. The movement emerged from Father Charles Coughlin's radio following and drew support from Catholics who saw communism as the primary threat and Jews as communism's masters. Gallagher, a historian and Jesuit priest, traces how the Front recruited from Catholic neighborhoods in Boston and New York, trained members in street fighting, and stockpiled weapons for an anticipated uprising. He examines the FBI's investigation, which revealed connections between the Front and German intelligence, and the trial that exposed the movement's plans while ultimately acquitting its leaders. The book shows how antisemitism and anti-communism combined with Catholic social teaching to produce a distinctly American fascism that its adherents saw as patriotic and Christian. Gallagher places the Christian Front within broader patterns of American extremism while attending to its specifically Catholic dimensions. The story challenges assumptions about American immunity to fascism and the religious communities that have sometimes harbored it.
