Africa's equatorial rain forests cover an area roughly the size of continental Western Europe, and yet the history of this area remains largely unexplored. Robert Harms makes an important advance in this book toward recovering that history by telling the story of the Nunu, who live in and around the swampy floodplains of the middle Zaire River. A key element in Nunu history has been the small-scale, short-distance migrations that continually led individuals and groups into new micro-environments. When an increasing population impinged upon the limits of available resources in the late eighteenth century, a crisis characterized by drastic change and incessant conflict ensued. The Nunu abandoned their ancestral estates to take up new forms of competition in river towns, causing a conflict of identity which culminated in civil war in the 1960s.
