Thompson writes a history of those African slaves that preferred to run into the unknown wilds of the American continent than to remain in bondage. These self-freed slaves sought not only their own freedom but oftentimes set up competing polities that defied and frightened the authoritarian state of the burgeoning plantocracy. Thompson focuses not only on the means that these men and women used to gain and defend their personal freedom but also on the organization of their communities, their economy, defense and the accommodations they were prepared to make with the authoritarian state. Covering the whole of the Americas between the 16th and 19th century, Thompson focuses on the common threads in the formation of all of these communities rather than chronicle any one in particular detail. This was an important, if at times dense, book that sought to give due recognition to these courageous men and women who fought against terrible odds for their freedom.
