This image shows a photograph from the early 1920s, probably in Portland, in which robed and hooded Ku Klux Klan members share a stage with members of the Royal Riders of the Red Robe, a Klan auxiliary for foreign-born white Protestants. A large banner reading “Jesus Saves” occupies a prominent position on the wall at the rear of the stage and testifies to the strong role that Protestantism played in the KKK philosophy of “100 percent Americanism,” an ideology that developed during World War I as a reaction to the perceived threat to national unity posed by the influx of non-Protestant, non-English-speaking immigrants.
