Kent State University
Kent, Ohio

“The Kent State shootings (also known as the May 4 massacre and the Kent State massacre) were the killing of four and wounding of nine unarmed college students by the Ohio National Guard on the Kent State University campus. The shootings took place on May 4, 1970, during a rally opposing the expanding involvement of the Vietnam War into Cambodia by United States military forces as well as protesting the National Guard presence on campus and the draft.
“Twenty-eight National Guard soldiers fired about 67 rounds over 13 seconds, killing four students and wounding nine others, one of whom suffered permanent paralysis.”
“In response to, and protest of, the Kent State shootings, Neil Young wrote the song ‘Ohio’ which was performed by the folk rock group Crosby, Stills, Nash & Young.”
