The Volta-Bani War was an anti-colonial rebellion which took place in French West Africa (specifically, the areas of modern Burkina Faso and Mali) between 1915 and 1917. It was a war between an indigenous African force drawn from a diverse coalition of local peoples who rose against the French Army. At its height in 1916 the rebels mustered from 15,000–20,000 men and fought on several fronts. After about a year and several setbacks, the French army defeated the insurgents and jailed or executed their leaders but resistance continued until 1917.
