Since the 1960s, University of Maryland students have been extremely vocal in advocating for peace. The largest peace protests occurred on campus in 1970, when the National Guard was deployed to curb a massive anti-Vietnam War protest staged by students on Route 1 and McKeldin Mall. Since the 1970s, students have been active in protesting war and acts of violence, including the Gulf War in the 1990s and the ongoing Israeli-Palestinian conflict.
