Set aside your preconceptions about the Klan, from the era of Reconstruction. As the distinguished historian Linda Gordon demonstrates in this chilling account, the KKK of the 1920s was urban, northern, and modern. Its wizards and dragons used the latest tools of mass advertising to spread their message of 'true Americanism' racial purity, religious intolerance, and opposition to immigration. Its members, one in six of whom were women, favored women's suffrage. Its campaign of terror ended not long after it began, but it left on American politics its dark mark.–Jill Lepore, author of The Secret History of Wonder Woman
