International Workers’ Day, often referred to as May Day, is a celebration of labourers and the working classes that is promoted by the international labour movement which occurs every year on May Day (1 May), an ancient European spring festival.
The date was chosen by a pan-national organization of socialist and communist political parties to commemorate the Haymarket affair, which occurred in Chicago on 4 May 1886.
The Haymarket Massacre was the aftermath of a bombing that took place at a labor demonstration at Haymarket Square in Chicago. It began as a peaceful rally in support of workers striking for an eight-hour work day, the day after police killed one and injured several workers.
An unknown person threw a dynamite bomb at the police as they acted to disperse the meeting, and the bomb blast and ensuing gunfire resulted in the deaths of seven police officers and at least four civilians; dozens of others were wounded.
