In a book that has become a modern classic of social movement organizing, Mark and Paul Engler explain that there is a craft to uprising—and that this craft can change the world. From protests around climate change and immigrant rights, to #BlackLivesMatter and movements to defend democracy, a new generation is unleashing strategic nonviolent action to shape public debate and force political change. While mass movements are often portrayed as spontaneous and unpredictable, Mark and Paul Engler explore the hidden art behind such outbursts of protest, examining core principles that have been used to spark and guide moments of transformative unrest. Now updated with new material discussing the major mobilizations of the past decade—including #MeToo, protests for racial and climate justice, and anti-Trump resistance—This Is an Uprising shows how new protest movements can be essential in fighting authoritarianism and advancing social and economic justice today.
