The exploration of Tibesti, Erdi, Borkou, and Ennedi in 1912-1917

In The Exploration of Tibesti, Erdi, Borkou, and Ennedi in 1912-1917, Jean Tilho records a major scientific and geographic mission across the central Sahara, undertaken under the auspices of the French Institute. The book combines expedition narrative, topographical observation, and ethnographic notice, offering a meticulous account of remote regions then only imperfectly known to European scholarship. Its style is characteristic of early twentieth-century exploratory prose: precise, empirical, and often austere, yet animated by the intellectual ambition of mapping landscapes, peoples, and routes within a broader colonial-scientific framework. Tilho, a French military officer, geographer, and surveyor, was especially equipped for such work through his technical training and experience in African exploration. His career joined strategic, cartographic, and scientific interests, and this mission reflects the period when French imperial administration relied upon disciplined field observation to consolidate knowledge of Saharan territories. The book thus emerges not merely as travel writing, but as a document shaped by the entanglement of scholarship, state power, and exploration. This volume is strongly recommended to readers interested in Saharan history, colonial geography, and the literature of exploration. It rewards close attention as both a primary historical source and a revealing example of how knowledge of Africa was produced in the early modern imperial age.
