Routledge Library Editions: Sudan [PDF ebook] 

This 5 volume set brings together research into the Sudan, works both modern and classic. Two works examine the Sudan of the late nineteenth century, a time when Anglo-Egyptian domination was enforced on the country; two works detail the Sudan of the twentieth century, looking at its politics, economy and society; and a last work traces the roots of modern Sudan through the historic tribes of the region.
