The raised fist, or the clenched fist, is a long-standing image of activism, often a symbol of social revolution and political solidarity. It is also a common symbol of anarchism and communism, but can also be used as a salute to express unity, strength, or resistance. The origin of the raised fist as a symbol is unclear. Its use in trade unionism, anarchism, and the labor movement had begun by the 1910s. William "Big Bill" Haywood, a founding member of the Industrial Workers of the World, used the metaphor of a fist as something greater than the sum of its parts during a speech at the 1913 Paterson silk strike.

International Workers' Day, often referred to as May Day, is a celebration of laborers and the working classes that is promoted by the international labor movement and occurs every year on May Day (1 May). In 1889, May Day was chosen as the date for International Workers' Day by the socialists and communists of the Second International, as well as anarchists, labor activists, and leftists in general around the world, to commemorate the Haymarket affair in Chicago and the struggle for an eight-hour working day. They adopted a resolution for a "great international demonstration" in support of working-class demands for the eight-hour day. The 1904 Sixth Conference of the Second International,

The Haymarket affair was the aftermath of a bombing that took place at a labor demonstration on May 4, 1886, at Haymarket Square in Chicago. It began as a peaceful rally in support of workers striking for an eight-hour workday after police killed one and injured several workers. An unknown person threw a dynamite bomb at the police as they acted to disperse the meeting, and the bomb blast and ensuing gunfire resulted in the deaths of seven police officers and at least four civilians; dozens of others were wounded. In the internationally publicized legal proceedings that followed, eight anarchists were convicted of conspiracy. Seven were sentenced to death and one to a term of 15 years in prison. The Haymarket Affair is generally considered significant as the origin of International Workers' Day held on May 1, and it was also the climax of the social unrest among the working class in America known as the Great Upheaval.
