The Beatles
This band, comprising of John Lennon, Paul McCartney, George Harrison, and Ringo Starr, is one of the most popular bands in pop culture history. From Liverpool to-- well, everywhere, they took the world by storm in the 1960s. Lennon himself believed that they were "bigger than Jesus". Lennon, the most well-known Beatle, is often thought to be the leader of their protests. Now, normal protests typically consist of 3-400 people. This protest, however, had millions behind one man. Leaders couldn't ignore this. Many still believe that Lennon single-handedly ended the Cold War- and this may well be true. After a few years, Lennon married Yoko Ono, who is often blamed for the Beatles breaking up. After Lennon's death, Ono still had some notoriety- but not for long. Harrison would die of cancer in 2001, while Starr and McCartney are still in the limelight even today.
