Last year’s march was one of the largest student-led anti-violence efforts in Chicago history. This year, students were encouraging community members and leaders to join them, to help spread a message of peace and social responsibility.

Mayor Rahm Emanuel will join a 9:30 a.m. rally before the march. After the group marches to Perspectives’ IIT/Math and Science Academy in Bronzeville, they will hold a “peace jam,” featuring music, performances, and speeches from students and supporters.
