This eleventh edition was developed during the encyclopaedia's transition from a British to an American publication. Some of its articles were written by the best-known scholars of the time and it is considered to be a landmark encyclopaedia for scholarship and literary style.

In 'Klansville, U.S.A.', David Cunningham tells the story of the astounding trajectory of the Klan during the 1960s by focusing on the pivotal and under-explored case of the United Klans of America (UKA) in North Carolina. Why the KKK flourished in the Tar Heel state presents a puzzle and a window into the complex appeal of the Klan as a whole.

In popular understanding, the Ku Klux Klan is a hateful white supremacist organization. In Ku Klux Kulture, Felix Harcourt argues that in the 1920s the self-proclaimed Invisible Empire had an even wider significance as a cultural movement. Ku Klux Kulture reveals the extent to which the KKK participated in and penetrated popular American culture, reaching far beyond its paying membership to become part of modern American society. The Klan owned radio stations, newspapers, and sports teams, and its members created popular films, pulp novels, music, and more. Harcourt shows how the Klan’s racist and nativist ideology became subsumed in sunnier popular portrayals of heroic vigilantism.

The Ku Klux Klan came to Canada thanks to some energetic American promoters who saw it as a vehicle for getting rich by selling memberships to white, mostly Protestant Canadians. In Ontario, Saskatchewan, Alberta and British Columbia, the Klan found fertile ground for its message of racism and discrimination targeting African Canadians, Jews and Catholics. While its organizers fought with each other to capture the funds received from enthusiastic members, the Klan was a venue for expressions of race hatred and a cover for targeted acts of harassment and violence against minorities. Historian Allan Bartley traces the role of the Klan in Canadian political life in the turbulent years of the 1920s and 1930s, after which its membership waned. But in the 1970s, as he relates, small extremist right- wing groups emerged in urban Canada, and sought to revive the Klan as a readily identifiable identity for hatred and racism. The Ku Klux Klan in Canada tells the little-known story of how Canadians adopted the image and ideology of the Klan to express the racism that has played so large a role in Canadian society for the past hundred years — right up to the present.

Indiana had the largest and most politically significant state organization in the massive national Ku Klux Klan movement of the 1920s. Using a unique set of Klan membership documents, quantitative analysis, and a variety of other sources, Leonard Moore p
