NATALIE J. SWANEPOEL, while a student at Syracuse University, Syracuse, New York, was awarded a grant in January 2001 to aid research on 'Social and Political Change on the Slave-Raiding Frontier: Nineteenth Century Sisalaland, Northern Ghana,' supervised by Dr. Christopher R. DeCorse. The aim of the research was to investigate the changes that occurred among the Sisala -- a 'decentralized' society during the nineteenth century as a result of increased (slave) warfare and an expanded trade network. Twelve months of archaeological, archival and oral historical research was carried out between April 2001 and August 2002. Archaeological research concentrated on the late nineteenth century site of Yalingbong, a naturally fortified hilltop that was used as a refuge during a war that took place between a local village, Kpan, and the Zaberma, a group of armed, Islamic horsemen. In addition, it was used as a base of operations by the Kpan community in their own raids against neighboring communities while also acting as a trade center in the region. Mapping, surface collections and test excavations were conducted at fourteen of a possible thirty loci. Supported by documentary and oral historical evidence the archaeological finds shed light on the complexity of the domestic slave trade in Africa, the expansion of trade networks in the African interior, the nature of warfare, the impact of colonial administration in northern Ghana and the changing political structure of 'decentralized' societies as a response to increased warfare.
