Today is May Day! Also known as International Workers’ Day. May Day is considered an international labor holiday. This post highlights some of the materials in our collections related to May Day. Much of our May Day material can be found in the May Day, 1885-1986 folder in the vertical file collection, and the Haymarket folders in the Morris B. Schnapper collection!
May Day was created by a resolution initiated by American Socialists at the International Socialist Congress in Paris, France, in July of 1889. The purpose of May Day was to gain support for an eight-hour work day. The Federation of Organized Trades and Labor Unions of the United States and Canada, precursor to the American Federation of Labor, and the Knights of Labor cooperated in preparing for a general strike in U.S. cities on May 1, 1886. And on that day, approximately 350,000 American workers went on strike, impacting over 11,000 businesses. Although workers in New York, Baltimore, Detroit, Milwaukee, and other cities participated, Chicago was widely considered the center of May Day agitation, largely due to Chicago being one of the few cities with broad union and radical solidarity in support of the eight-hour day.
