"The Democrats did play a role in Reconstruction--they worked to block it. The party struck out against Reconstruction in two ways. The first was to form a network of terrorist organizations with names like the Constitutional Guards, the White Brotherhood, the Society of Pale Faces, and the Knights of the White Camelia. The second was to institute state-sponsored segregation throughout the South. Let us consider these two approaches one by one. The Democrats started numerous terror groups, but the most notorious of these was the Ku Klux Klan. Founded in 1866, the Klan was initially led by a former Confederate army officer, Nathan Bedford Forrest, who served two years later as a Democratic delegate to the party's 1868 national convention. Forrest's role in the Klan is controversial; he later disputed that he was ever involved, insisting he was active in attempting to disband the organization. Initially the Klan's main targets weren't blacks but rather white people who were believed to be in cahoots with blacks. The Klan unleashed its violence against northern Republicans who were accused of being "carpetbaggers" and unwarrantedly interfering in southern life, as well as southern "scalawags" and "white niggers" who the Klan considered to be in league with the northern Republicans. The Klan's goal was to repress blacks by getting rid of these perceived allies of the black cause. Once again Republicans moved into action, passing a series of measures collectively termed the Ku Klux Klan Acts of 1871. These acts came to be known as the Force Bill, signed into law by a Republican President, Ulysses Grant. They restricted northern Democratic inflows of money and weapons to the Klan, and also empowered federal officials to crack down on the Klan's organized violence. The Force Bill was implemented by military governors appointed by Grant. These anti-Klan measures seem modest in attempting to arrest what Grant described as an "invisible empire throughout the South." But historian Eric Foner says the Force Bill did markedly reduce lawless violence by the Democrats. The measures taken by Republicans actually helped shut down the Ku Klux Klan. By 1873, the Klan was defunct, until it was revived a quarter-century later by a new group of racist Democrats."
