In this brilliant book, Isabel Wilkerson gives us a masterful portrait of an unseen phenomenon of an America shaped by a hidden caste system. A rigid hierarchy of human rankings that links the caste systems of America, India, and Nazi Germany, Wilkerson explores eight pillars that underlie caste systems across civilizations, including divine will, bloodlines, stigma, and more. Using riveting stories about people--including Martin Luther King, Jr., baseball's Satchel Paige, a single father and his toddler son, Wilkerson herself, and many others--she shows the ways that the insidious undertow of caste is experienced every day.
