Sherman Jackson offers a trenchant examination of the career of Islam among the blacks of America. Jackson notes that no one has offered a convincing explanation of why Islam spread among Blackamericans (a coinage he explains and defends) but not among white Americans or Hispanics. The assumption has been that there is an African connection. In fact, Jackson shows, none of the distinctive features of African Islam appear in the proto-Islamic, black nationalist movements of the early 20th century. Instead, he argues, Islam owes its momentum to the distinctively American phenomenon of "Black Religion," a God-centered holy protest against anti-black racism.
