Kent State University is best known, outside Ohio, for a single event: The Kent State Massacre, which involved the shooting of student demonstrators by the National Guard on May 4, 1970. Students were protesting against protesting against American involvement in the Vietnam War; the demonstrations had arisen in response to the invasion of Cambodia that President Richard Nixon launched on May 1. Four students were killed, and several others were wounded. A photograph of a 14-year-old runaway girl, kneeling over one of the bodies as she cried, is one of the most enduring images of the tragedy, and it won a Pulitzer Prize for photographer John Filo.
