Ouaddai WarChad · 1909–1911“A thread from the great cord of two hundred and fifty. Hold it while I speak.”Wadai was the last great sultanate of the central Sudan to bow — a state of sultans and caravan tolls east of Lake Chad, trading north to Benghazi. France took its capital Abéché in 1909 and spent years more breaking the resistance that refused to agree the war was over.
