The immune response to viral infection comprises innate and adaptive defenses. The innate response, which we have discussed previously, functions continuously in a normal host without exposure to any virus. Most viral infections are controlled by the innate immune system.
The original Ku Klux Klan was organized by ex-Confederate elements to oppose the Reconstruction policies of the radical Republican Congress and to maintain white supremacy..
The KKK was formed as a social group in Tennessee in 1866. The name probably came from the Greek word kuklos, meaning circle.. Klan was an alliterative version of clan, thus Ku Klux Klan suggested a circle, or band, of brothers. With the passage of the Military Reconstruction Acts in March 1867, and the prospect of freedmen voting in the South, the Klan became a political organization.
