Unequal opportunity sparked Jim Brown’s endeavors to encourage Black development while Billie Jean King fought so that women tennis players could earn more money and enjoy greater freedom. Gregory J. Kaliss examines these events and others to guide readers through the unprecedented wave of protest that swept sports in the 1960s and 1970s. The little-known story of the University of Wyoming football players suspended for their activism highlights an analysis of protests by college athletes. The 1971 Muhammad Ali-Joe Frazier clash provides a high-profile example of the Black male athlete’s effort to redefine Black masculinity. An in-depth look at the American Basketball Association reveals a league that put Black culture front and center with its style of play and shows how the ABA influenced the development of hip-hop. As Kaliss describes the breakthroughs achieved by these athletes, he also explores the barriers that remained—and in some cases remain today.
