The first day of May is the International Worker’s Day, May Day, or Labor Day, a day promoted by socialists, communists, anarchists, and the labor movement. Even though it is presented on quick search on the web as “an ancient European spring festival,” the date was chosen by the Second International, an organization founded by socialist and communist parties to celebrate the Haymarket event which occurred in Chicago on May 4, 1886, when marchers threw a bomb at police and policemen responded by shooting into the crowd, killing four people.
In 1904 the International Socialist Conference in Amsterdam, the sixth conference of the Second International, “called on all Social Democratic Party organizations and trade unions of all countries to demonstrate energetically on the First of May for the legal establishment of the 8-hour work day, for the class demands of the proletariat, and for universal peace.”
