What to read after A Concise History of South Sudan?

This textbook in history is primarily intended for secondary schools in South Sudan. The focus is on the history of South Sudan, and is in this sense a pioneer work since it is the country's first secondary school book dealing primarily with the history of the South. Even though the focus is on South Sudan its history cannot be interpreted in a vacuum, and particularly North-South relations are discussed extensively in the book. Secondary school students in Sudan have either studied the history of Kenya and Uganda, or the history of North Sudan since no history book for South Sudan has existed. The book may also be of interest to academics, politicians, historians and college and university students as well civil society groups such as churches, youth and women's groups.
