The Trans-Saharan Railway and the Politics of Imperial Expansion, 1890–1900

The trans-Saharan railway scheme was the dominant, if intermittent, theme of French African expansion in the last 20 years of the nineteenth century. Behind political and economic arguments for the scheme lay a hidden agenda—the promotion of Algerian railway interests. Its revival in 1890, after a ten-year interval, was driven by a need to safeguard returns on railway investments, threatened by the growing political influence of the Radicals. Success in a campaign on its behalf was dependent on reinvigorating empire-building in tropical Africa, a function performed by the Chad plan, which also provided the required territorial configuration for a trans-Saharan railway. Subsequently, interest shifted from West Africa to the Sahara where efforts to promote railway construction through exploitation of the Tuat question stood greater chances of success. Saharan expansion was delayed for almost a decade by the obstinacy of the Algerian generals and the timidity of governments in France, before finally being resolved by a fait accompli. However, political circumstances at home, and the emergence of new railway competition in the Sahara, prevented the railway companies from reaping the full reward for their efforts. On the map, if not in any practical sense, a territorially unified French African empire had been completed by 1900, whose origins can be traced directly to the activities of the railway lobby.
