We have already discussed the expansion of propaganda, so that its enormous utilization by the Klan is quite comprehensible. But even the constant reiteration of laudable motives and grandiloquent phrases about Americanism cannot account for this sudden rise to power; two other elements must be included—group prejudice and secrecy. The Klan capitalized every prejudice of its group, which was predominantly a small-town one, of American birth, Protestant religion, and Anglo-Saxon either in race or in their opinion of their race. And the Klan met in utter secrecy, did not divulge the names of its members, paraded the streets in the disguise of robes and masks, and carried out its deeds of violence in the same awe-inspiring anonymity. Clearly, the Klan is typical of the tendencies we have found in the American mind after the war. It represents a subgroup revolting against its voluntary sacrifices for the nation during the war. It represents the anti-alien, anti-Catholic and now also anti-Jewish sentiment, the reaction against the enormous wave of immigration just at an end. It includes also the fear and hatred of the negro, strongest in the old South but spreading to the North with the northern migration of many negroes during and after the war. On the Pacific coast the fear of the Japanese immigration enters into the complex of hatreds. In other words, the Klan is the third wave of Nativism. It is the great reaction of the subgroup to the intense sacrifice for the nation during the war. 2. Various other motives are implicated in this general complex. The South furnished the original soil of the Klan; its second center was the middle west, the old home of the A. P. A. It was weakest on the Atlantic and Pacific coasts (except Oregon) where the various immigrant groups actually live. It was weak in the heterogeneous masses of the cities with their aliens, Catholics and Jews; strongest in the small town, where men may talk of the Papal menace without actually knowing many Catholics, of the Elders of Zion without seeing personally more than one or two Jews a year. The attitude of Nativism, the reaction to the immigration of huge masses of foreigners, is still strongest where these foreigners themselves are not in evidence.
