How did Cassius Clay become Muhammad Ali? Why was he the most polarizing athlete in America during the 1960s? Historian Johnny Smith will answer these questions and discuss his new book, Blood Brothers, the first in-depth portrait of the pivotal friendship between Muhammad Ali and Malcolm X. Professor Smith will explain the central role Malcolm X played in the life of Muhammad Ali and how the politics of the Nation of Islam broke the bond between these two icons. Blood Brothers is a tale of friendship and brotherhood, love and deep affection. It is also a story of deceit, betrayal, and violence—inside and outside the ring—during a troubled time in America.
