The KENT STATE MASSACRE were the shootings on May 4, 1970, of unarmed college students by the Ohio National Guard at Kent State University in Kent, Ohio, during a mass protest against the bombing in neutral Cambodia by United States military forces. Twenty-eight National Guard soldiers fired approximately 67 rounds over a period of 13 seconds, killing four students and wounding nine others, one of whom suffered permanent paralysis.
Some of the students who were shot had been protesting against the Cambodian Campaign, which President Richard Nixon announced during a television address on April 30 of that year. Other students who were shot had been walking nearby or observing the protest from a distance.
There was a significant national response to the shootings: hundreds of universities, colleges, and high schools closed throughout the United States due to a student strike of four million students, and the event further affected public opinion, at an already socially contentious time, over the role of the United States in the Vietnam War.
