Workers of the world unite, you have nothing to lose but your chains
Poster art celebration of May 1
STRIKING: (L to R) Gustav Klutsis: May 1 day of international proletarian solidarity, 1930; Unknown designer, GDR: 1 May - day of working class celebration and struggle; Giladi Goffer: May 1 poster for Histadrut, 1959

The slogan “Workers of the world unite...”  from The Communist Manifesto by Marx and Engels is one of the rallying cries celebrating May Day — International Workers’ Day — and the historic struggles and gains made by workers and the labour movement globally over generations of class struggle.

As a commemoration, May Day’s origins lie in the Haymarket Massacre, the bombing of a peaceful rally in support of Chicago workers striking for an eight-hour working day in 1886.

Since then, inspiring poster images such as these reflect a spirit of optimism and political resolution, demonstrating May Day’s growing significance internationally and the message that “the workers united can never be defeated.”
