The Ku Klux Klan by Annie Cooper Burton

The Ku Klux Klan), commonly called the KKK or the Klan, is an American white supremacist hate group, whose primary target is African Americans The Klan has existed in three distinct eras at different points in time during the history of the United States. Each has advocated extremist reactionary positions such as white nationalism, anti-immigration and—especially in later iterations—Nordicism and anti-Catholicism. Historically, the First Klan used terrorism – both physical assault and murder – against politically active blacks and their allies in the South in the late 1860s, until it was suppressed around 1872. All three movements have called for the "purification" of American society and all are considered right-wing extremist organizations. In each era, membership was secret and estimates of the total were highly exaggerated by both friends and enemies.
The first Klan flourished in the Southern United States in the late 1860s during Reconstruction, then died out by the early 1870s. It sought to overthrow the Republican state governments in the South, especially by using violence against African-American leaders. Each chapter was autonomous and highly secret as to membership and plans. Its numerous chapters across the South were suppressed around 1871, through federal law enforcement. Members made their own, often colorful, costumes: robes, masks and conical hats, designed to be terrifying and to hide their identities.^[The second Klan started small in Georgia in 1915. It grew after 1920 and flourished nationwide in the early and mid-1920s, including urban areas of the Midwest and West. Taking inspiration from D. W. Griffith's 1915 silent film The Birth of a Nation, which mythologized the founding of the first Klan, it employed marketing techniques and a popular fraternal organization structure. Rooted in local Protestant communities, it sought to maintain white supremacy, often took a pro-Prohibition stance, and it opposed Catholics and Jews, while also stressing its opposition to the alleged political power of the Pope and the Catholic Church. This second organization was funded by initiation fees and selling its members a standard white costume. The chapters did not have dues. It used K-words which were similar to those used by the first Klan, while adding cross burnings and mass parades to intimidate others. It rapidly declined in the later half of the 1920s.
