History
The south lay beyond the reach of the Saharan trade routes and was for centuries the raiding ground of the Muslim sultanates to the north — Baguirmi, Ouaddaï and, in the 1890s, Rabih az-Zubayr — whose slave raids depopulated whole districts and left a deep distrust of the north. The Sara and their neighbours lived in scattered villages rather than states, organised by lineage and by initiation societies.
French rule after 1900 transformed the region. Fort-Archambault, founded on the Chari in 1899 and renamed Sarh in 1972, became a garrison town, and from the late 1920s the colonial administration imposed compulsory cotton growing on southern farmers, with harsh penalties for those who resisted. Missions and schools followed, so that at independence in 1960 the educated elite, the army's officers and the first president, François Tombalbaye, were southerners. His campaign of cultural "authenticity" in the 1970s included forcing civil servants through the Sara yondo initiation, before he was killed in a coup in 1975.
After northern forces took N'Djamena in 1979 and 1980, the south became the base of resistance, and fighting between government troops and southern rebels in the early 1980s, including massacres of civilians in 1984, left lasting scars. Oil changed the economy from 2003, when the Doba fields began exporting through the pipeline to Kribi in Cameroon.
