Artists Rendition of the Haymarket Affair

The Haymarket affair (also known as the Haymarket massacre or Haymarket riot)
was the aftermath of a bombing that took place at what began as a peaceful labor
rally on Tuesday May 4, 1886, at Haymarket Square in Chicago. Workers were
striking for an eight-hour work day when an unknown person threw a dynamite
bomb at police as they tried to disperse the demonstration. The bomb and
resulting gunfire left seven police officers and at least four civilians dead,
and many others wounded. The confrontation is generally considered
significant as the origin of international May Day labor observances.

The Ohio National Guardsmen opened fire on students during an anti-
Vietnam war protest at Kent State University. Four students were killed
and nine others were wounded.

At Kent State University a demonstration with about 500 students was held
on Friday, May 1 on the Commons, a grassy knoll in the center of campus. As
the crowd dispersed without incident to attend classes by 1 pm that afternoon,
another rally was planned for Monday, May 4 to continue the protest of president
Nixon’s expansion of the Vietnam War into Cambodia.
