Students of late nineteenth century history have long dismissed the world industrial expositions as glittering, but not highly significant reflections of the gilded age. What emerges from the literature of the period, however, is a sense of the overriding commercial importance of these exhibitions. Nineteenth-century observers consistently linked the fairs to the general growth of world trade and to the expanding commercial hegemony of the United States. More specifically, contemporaries agreed that the expositions served to develop trade and investment ties with Latin America. Among the Latin American countries represented in the expositions, Mexico was the most important and consistent participant.
