The second group was founded in the South in 1915 and it flourished nationwide in the early and mid-1920s, including urban areas of the Midwest and West.
Taking inspiration from the film Birth of a Nation, which mythologized the founding of the first Klan, it employed marketing techniques and a popular fraternal organization structure.
They had played with an engine of power and mystery, though organized on entirely innocent lines, and found themselves overcome by a belief that something must lie behind it all—that there was, after all, a serious purpose, a work for the Klan to do." Klan groups spread throughout the South as an insurgent movement promoting resistance and white supremacy during the Reconstruction Era. In 18, the federal government passed the Enforcement Acts, which were intended to prosecute and suppress Klan crimes.
The first Klan had mixed results in terms of achieving its objectives.
The members had conjured up a veritable Frankenstein. As a secret vigilante group, the Klan targeted freedmen and their allies; it sought to restore white supremacy by threats and violence, including murder, against black and white Republicans.It seriously weakened the black political establishment through its use of assassinations and threats of violence; it drove some people out of politics.On the other hand, it caused a sharp backlash, with passage of federal laws that historian Eric Foner says were a success in terms of "restoring order, reinvigorating the morale of Southern Republicans, and enabling blacks to exercise their rights as citizens".as a fraternal social club inspired at least in part by the then largely defunct Sons of Malta.It borrowed parts of the initiation ceremony from that group, with the same purpose: "ludicrous initiations, the baffling of public curiosity, and the amusement for members were the only objects of the Klan", according to Albert Stevens in 1907.
