“May Day is about affirmation, the love of life, and the start of spring, so it has to be about the beginning of the end of the capitalist system of exploitation, oppression, war, and overall misery, toil, and moil.” So writes celebrated historian Peter Linebaugh in an essential compendium of reflections on the reviled, glorious, and voltaic occasion of May 1st. It is a day that has made the rich and powerful cower in fear and caused Parliament to ban the Maypole—a magnificent and riotous day of rebirth, renewal, and refusal. These reflections on the Red and the Green—out of which arguably the only hope for the future lies—are populated by the likes of Native American anarcho-communist Lucy Parsons, the Dodge Revolutionary Union Movement, Karl Marx, José Martí, W.E.B. Du Bois, Rosa Luxemburg, SNCC, and countless others, both sentient and verdant. The book is a forceful reminder of the potentialities of the future, for the coming of a time when the powerful will fall, the commons restored, and a better world born anew.
