Answer:
Sherman Anti-Trust Act
Explanation:
Approved July 2, 1890, The Sherman Anti-Trust Act was the first Federal act that outlawed monopolistic business practices.
The Ku Klux Klan was created after Abraham Lincoln had claimed slavery was no longer legal. The KKK went around, killing black people and such. They also protested around the segregation process. They are still around to this day, but I don't believe that are killing anymore.
