Ku klux klan??? someone please help me?

It was the right after WWI so there were a lot of changes in the world. I don't know specifically the KKK but I do know that in the 20's is when sound was introduced into movies. That was a huge thing in that time. Entertainment became more popular because people had the time and the money to be able to have leisure time. Also radio got big in the 20's as did jazz music. You really should look it up it is a fascinating decade.
