The struggle over slavery divided not only the American nation but also the hearts and minds of individual citizens faced with the timeless problem of when to submit to unjust laws and when to resist. Here Andrew Delbanco examines slavery through the lens of politics, law, and the narratives of enslaved black people who risked their lives to flee from bondage, and in this New York Times Notable Book, he illuminates what brought us to war with ourselves, and the terrible legacies of slavery that are with us still.
