A fine historico-political analysis of the North African sore spot by a writer, well grounded in British university tradition, who returned to his native Sudan as a director of the large Gazira irrigation plan. After orientation in a short first chapter scholarly in tone as is the rest of the book, but well layered with lively observations- on the geography and people of the Sudan, Mr. Abbas begins historical analysis. Moslems ruled from 1820 to 1884. Revolt and a native regime were overpowered by British conquest, followed in the early 20's by the revival of Egyptian claims and in the 30's by the rising social awareness of the Sudanese themselves. In sympathy with his people, Mr. Abbas does have a clear view of the complexity of problems faced by the Egyptians who want to control the Nile and to have population outlets, by Britain and the U. N. as mediators, by the Sudanese themselves as a people desirous of a place in the world of nations. For those who want to know- excellent and complete with index and appendices on the Anglo -- Egyptian agreements and the southern Sudan- to the end of 1951.
