How did the 2nd KKK come to an end 1920s?

The KKK came to an end in the 1920s through corruption from within the Klan itself and society. The Klan's more violent activities (such as lynchings, robbings, and burnings) started to offend the conscience of Americans and membership decreased. That, along with numerous accounts of fraud, sexual scandals, accusation of crimes, and money mishandling led to the demise of the KKK.
