Despite several decades of scholarship on African diasporic religion, Voodoo remains underexamined, and the few books published on the topic contain inaccuracies and outmoded arguments. In Jeffrey E. Anderson presents a much-needed modern account of the faith as it existed in the Mississippi River valley from colonial times to the mid-twentieth century, when, he argues, it ceased to thrive as a living tradition. Anderson provides a solid scholarly foundation for future work by systematizing the extant information on a religion that has long captured the popular imagination as it has simultaneously engendered fear and ridicule. His book stands as the most complete study of the faith yet produced and rests on more than two decades of research, utilizing primary source material alongside the author’s own field studies in New Orleans, Haiti, Cuba, Senegal, Benin, Togo, and the Republic of Congo. The result serves as an enduring resource on Mississippi River valley Voodoo, Louisiana, and the greater African Diaspora.
