The breadth and impact of Black Lives Matter in the United States has been extraordinary. Between 2012 and 2016, thousands of people marched, rallied, held vigils, and engaged in direct actions to protest and draw attention to state and vigilante violence against Black people. What began as outrage over the 2012 murder of Trayvon Martin and the exoneration of his killer, and accelerated during the Ferguson uprising of 2014, has evolved into a resurgent Black Freedom Movement, which includes a network of more than fifty organizations working together under the rubric of the Movement for Black Lives coalition. Employing a range of creative tactics and embracing group-centered leadership models, these visionary young organizers, many of them women, and many of them queer, are not only calling for an end to police violence, but demanding racial justice, gender justice, and systemic change. In Making All Black Lives Matte, award-winning historian and longtime activist Barbara Ransby outlines the scope and genealogy of this movement, documenting its roots in Black feminist politics and situating it squarely in a Black radical tradition, one that is anticapitalist, internationalist, and focused on some of the most marginalized members of the Black community.
