The Confederate battle flag was not widely displayed in the South until school desegregation became an issue in the 1950's and it became the flag of the segregationists.

As the picture in the thread above shows, even the early 20th century KKK used the US flag, not any Confederate flag.

For example, the Confederate battle flag was only incorporated into the Georgia state flag in 1956, following Brown v. Board of Education.
