What were the names of the first KKK?

The first Ku Klux Klan, founded in 1865 in Pulaski, Tennessee, was originally called the "Invisible Empire of the South." It was later commonly referred to as the Ku Klux Klan, or simply the KKK. The group was established by former Confederate soldiers and aimed to restore white supremacy in the post-Civil War South through intimidation and violence against African Americans and their allies.
