President John F. Kennedy was the hope of all the americans that were treated unfairly. He was the "leader of the change" along with Martin Luther King, equality between black and white people, the stoppage of the Vietnam War, and freedom were the most important things that they fought for.
The world was an uproar and each person protested in a different way. For some people it was music, for others it was art, and for others it was their style. Everyone was expressing himself somehow so a lot of changes happened.
Musicians started to ptotest through music, when they sang their songs it was like hearing them talking to the world. They started doing rock which attracted people because it was something new, something different. Everyone started dancing freely and they followed the music with their hearts. Some noticeable world stars were The Beatles, Bob Dylan, Jimi Hendrix, The Rolling Stones or Janis Joplin, among others.
