Held from May to November in the Bois de Vincennes on the eastern outskirts of Paris, the 1931 International Colonial Exposition's official slogan was "The Tour of the World in One Day," and was intended to showcase France's imperial grandeur for the benefit of a metropolitan French audience, which numbered over 7 million over the six months the exposition was open. While the ICE has been analyzed as the crowning celebration of a colonial imaginary of la plus Grande France, "Greater France," this paper focuses specifically on the Palace of Morocco at the exposition. Drawing on archival documentation of the exhibit (including correspondence, drawings, and photographs), I examine how the Palace constituted a distilled representation of the French binary colonial construction pitting le vieux Maroc against France's own oeuvre in modernizing and developing Morocco, the mise en valeur of the Protectorate nation building project. It also looks at the Moroccan Sultan's visit to the ICE and the Palace of Morocco on August 7th, 1931, reconstructing the irony of the Sultan's "tour of Protectorate Morocco in one hour," accompanied by Hubert Lyautey (the first Resident General of Morocco and grand marshal of the ICE), which marked the symbolic apogee of the Protectorate fiction of a Franco-Moroccan partnership.
