France acquired the world's second largest overseas empire during the nineteenth century. This achievement appears all the more remarkable when measured against the scant holdings retained at the end of the Napoleonic Wars, the nation's weak industrial base, the banking community's marked preference for investment in the state debts of European and Mediterranean countries, the stagnant demographic pattern, and the mass of the population's distaste for imperialist adventures. Among those clamouring for the extension of imperial holdings could be found many military men and missionaries and a more restricted number of ideologues and politicians. But the strongest support for imperialism came from the business elites of the port cities and the centres of textile production. Despite their frequent invocations of grandeur and the mission civilisatrice, the motives of these bourgeois magnates remained essentially economic. They wanted the semi-colonial areas, as well as the colonies, to supply them with markets, raw materials and more profitable returns on investments. Local Chambers of Commerce, not unnaturally, became the pivotal institutions providing sustained support for imperialist endeavours. The provincial business communities discovered, however, that the realization of their economic dreams required more than economic activity. Most obviously, they had to deploy their substantial political influence in efforts to sway government policy. During the Third Republic, when France's empire reached its greatest extent, they also utilized the Chambers of Commerce to lend support to local geographical societies, colonialist organizations, colonial congresses, and endeavours in the field of imperial education. If these undertakings never completely realized the hopes of their backers, they still enjoyed successes substantial enough to call forth continued support.
