In 1969, Richard Nixon succeeded Johnson as President, and protests continued — not just against the war, but against the court trials and hearings of the Yippie leaders who became known as "the Chicago Seven" (originally "Chicago Eight"). Also in that year, a huge rock concert was held in Bethel, New York — the three day Woodstock Festival. At this festival, 500,000 hippies and music fans heard some of the most famous singers and groups of the time. The people there also did things like nude swimming, mud-sliding, rain-dancing and mass tribal chants. They did this to show their freedom to the world.
