The KKK's massive growth was driven by a sophisticated sales operation where recruiters (Cleagles) earned large commissions on new members' fees. This financial incentive, structured like a modern pyramid scheme, was a primary driver of its national expansion.

The second Klan, founded in 1915, was by far the largest, with up to five million members. Its power base was not the South but the industrial North and Midwest. While white supremacist, its primary focus was nativist, anti-Semitic, and especially anti-Catholic.

The Klan's explosive growth was not organic. PR professionals Edward Young Clark and Elizabeth Tyler treated the organization as a product, designing an aggressive sales operation and marketing message that resonated with public anxieties, transforming a failing club into a national force.

The Klan's terror campaign was a holistic effort to restore pre-war racial hierarchy. Beyond suppressing votes, they targeted Black churches, schools, landowners, and even women who displayed self-respect. This reveals a broader goal: to crush any sign of Black autonomy and re-establish total white supremacy in every aspect of Southern life.

The second KKK's rituals, particularly cross-burning, were not historical practices. They were invented for Thomas Dixon's novel "The Klansman" and popularized by D.W. Griffith's blockbuster film "The Birth of a Nation," demonstrating how mass media can create and legitimize radical aesthetics.

The Klan used a bizarre, fantasy-like hierarchy with titles like "Grand Goblin" and "Exalted Cyclops." This gamified structure provided status and escapism for men in ordinary towns, making a sinister organization feel like an exciting and exclusive club.

Rather than building from scratch, the KKK tapped into pre-existing social networks, particularly the Freemasons. Recruiters specifically targeted Masonic lodges, leveraging their membership lists and offering a familiar structure of ritual, networking, and community.

Contrary to the image of a fringe movement, the Klan was composed of and led by the Southern elite. Eyewitness accounts consistently identified lawyers, doctors, planters, and sheriffs as perpetrators of the violence. This highlights how extremist movements can be driven by the most powerful and 'respectable' members of a society.

Contrary to popular imagery, the original post-Civil War Ku Klux Klan never burned crosses. This iconic act of terror was introduced by the second Klan, founded in 1915, which was inspired by its depiction in the film "The Birth of a Nation."
