The harbor of Veracruz, and the harbors of Pánuco and Campeche were the main channels through which African slaves were introduced to Mexico. From there, they were taken to practically all parts of the country to work in mining, cattle raising and other activities. On the shores of Gulf of Mexico, Africans descendents held positions from mine and plantation workers, to servants and even landowners. As a result, important African settlements developed in this region.
