Activist Tom Hayden will be in Port Huron tonight to commemorate the Port Huron Statement.
A group of university students wrote the statement fifty years ago at a UAW retreat center north of Port Huron.
Hayden was one of the main participants, who was in his early twenties at the time.
The 25,000 word document addressed racism, poverty, the Cold War, and the nuclear arms race.
It was one of the first times there'd been a formal call-to-action for students to be part of a movement pushing for social change.
