The observation of Labor Day on the first Monday in September is usually attributed to the Knights of Labor who held their first parade on September 5, 1882. But far more important is the Haymarket Riot/Massacre of 1886.

It was in 1887 that Oregon became the first state to establish Labor Day as a holiday, which it put on the first Saturday in June. Colorado, Massachusetts, New Jersey, and New York observed Labor Day on the first Monday in September that year. Then in 1889, the First (Paris) Congress of the Second Socialist International selected May First as a day for international celebration of the working man, no matter what day of the week it fell on. May first was chosen in commemoration of the Haymarket Massacre which occurred in Chicago in 1886. In 1894, the first Monday in September was established as a federal holiday in the United States.

Peter J. McGuire, general secretary of the Brotherhood of Carpenters and Joiners and a co-founder of the American Federation of Labor, was first in suggesting a day to honor those "who from rude nature have delved and carved all the grandeur we behold."

Matthew Maguire, later the secretary of Local 344 of the International Association of Machinists in Paterson, N.J., proposed the holiday in 1882 while serving as secretary of the Central Labor Union in New York. Both men played an important part in staging the first Labor Day parade in New York City in September 1882.


"Labor Day differs in every essential from the other holidays of the year in any country," said Samuel Gompers, founder and longtime president of the American Federation of Labor. "All other holidays are in a more or less degree connected with conflicts and battles of man's prowess over man, of strife and discord for greed and power, of glories achieved by one nation over another. Labor Day...is devoted to no man, living or dead, to no sect, race, or nation."
