Mexico State was the scene of creative and evangelizing work of the Franciscans, as well as of the enterprising spirit of its sons, which brought about the work of exploiting the mines, cultivating haciendas and founding industry, a pioneering spirit that today continues to characterize the dynamic economy of the state; In all, this is a quick historic vision of Mexico State, from its remotest origins to the golden years of the Porfiriato.
