Each January, schools and offices close so that we may honor Martin Luther King. Jr., and the movement he gave his life to. Nearly two decades after his assassination, and after much public vilification, the civil rights leader was officially given a federal holiday commemorating his birth. While many of us welcome the time for rest, we aren’t always as consistent with using our day off from work as a day on for celebrating Black activists and scholars. These seven titles will help you dive deeper into all that King and his fellow organizers sacrificed to leave America more equitable than they received it.
