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..
They were more successful in achieving their political goals than they were with their social goals during the Reconstruction era. Origin 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.
