This work is a reconstruction of the Pre-colonial, colonial and post-colonial history of the Yakurr of South Eastern Nigeria. It is primarily, based on Yakurr Oral Sources. The Study provides a historical foundation hence its title. It is hoped that future historians shall build upon that foundation. However, the work examines the collapse of the Wukari Empire (Jukun/Kororofa) and the development of the Atlantic Slave trade as the principal causal factors of the migrations of the various peoples who now occupy the middle and upper Cross River Regions. Such people include the Yalla, Ukelle (upper Cross River), Boki, Agbo, Bahumono, Mbembe and Yakurr (middle Cross River) region.
