evidence: This chapter looks at one of Africa’s remotest peripheries: the Kafia Kingi enclave, a hilly area of about 15,000 square kilometers lying between Sudan’s South Darfur state and South Sudan’s Western Bahr el-Ghazal state, on the watershed of the Nile and Congo basins. That watershed also marks the border between the Central African Republic (CAR), Sudan, and South Sudan. In the first part of the twentieth century, Kafia Kingi was part of Bahr el-Ghazal; since 1960, it has been a district of South Darfur. At the time of writing, the enclave was the largest of several territories disputed by Sudan and the new Republic of South Sudan (RoSS), though according to the terms of the Comprehensive Peace Agreement (CPA), both countries have agreed to base border demarcation on the principle of return to the status quo at independence, in 1956.
