1886. May Day or International Workers' Day.
May Day has been set aside to commemorate the labor movement in many countries around the world. An international workers’ day was first called for in 1889 at the Second International, a meeting of socialists in Paris, France. The day was intended to honor anarchist workers who were sentenced to death following the Haymarket Square Riot in 1886 in Chicago, Illinois.Web: Encarta Encyclopedia
