International Labor Day (May Day) is today.
134 years ago today, on May 1, 1886, a group of workers came to Chicago to demand that their work be restricted to eight hours.
More than a thousand people joined the demonstration that day, shouting Work Harbor slogans, and on the third day, more than 65,000 workers took part.
May 3, 1886 is the decisive day of the strike.
A group of armed police officers, led by employers, attacked workers, killing four people.
On May 4, a group of workers gathered at Haymarket Square to protest the attack.
A police officer was also killed in a bomb attack when police and workers exchanged words.
It escalated into a confrontation, which left six policemen dead.
The number of workers killed in the conflict remains uncertain.
Labor leaders Augustus Spice, Albert Parsons, Adolf Fisher, George Engel, Samuel Fielden, Louis Ling, Michael Schwab, Oscar Nibbe were arrested and subsequently prosecuted.
Oscar Niebe was sentenced to 15 years in prison, while Samuel Fielden and Michael Schwab were sentenced to life imprisonment.
The other five were sentenced to death.
It was in 1889 that the International Labor Organization decided to permanently remember its red-blooded allies, demanding that they limit their hours to eight hours.
Accordingly, May 1st of each year is declared as International Labor Day.
