A MOST ANTICIPATED BOOK • From renowned organizers and activists Leah Hunt-Hendrix and Astra Taylor, comes the first in-depth examination of Solidarity—not just as a rallying cry, but as potent political movement with potential to effect lasting change.

“A window into what is possible when we reject the politics of division, trade individualism for interconnectedness and prioritize coming together for the greater good.”—Heather McGhee, author of The Sum of Us: What Racism Costs Everyone

Solidarity is often invoked, but it is rarely analyzed and poorly understood. Here, two leading activists and thinkers survey the past, present, and future of the concept across borders of nation, identity, and class to ask: how can we build solidarity in an era of staggering inequality, polarization, violence, and ecological catastrophe? Offering a lively and lucid history of the idea—from Ancient Rome through the first European and American socialists and labor organizers, to twenty-first century social movements like Occupy Wall Street and Black Lives Matter—Hunt-Hendrix and Taylor trace the philosophical debates and political struggles that have shaped the modern world.
