During the first decades of the present century, in that area of eastern Cuba which lies beyond a boundary formed by the Rio Cabreras in the north and the Rio Jobabo in the south, a unique social transformation took place which is of particular interest and importance. More than simply a transition from the traditional to the modern, Oriente's society underwent revolutionary change as a result not only of foreign influence but also of foreign control and design calculated to produce both modernization and ‘Americanization’. As it became increasingly apparent that these twin objectives could not be easily accomplished, a third consideration, economic, advantage, quickly emerged and rose to a position of dominance. Capital accumulation and the profit motive catalyzed a process of change produced by the reaction of two dissimilar cultures: one comparatively inert and native, the other highly dynamic and foreign, to produce sugar and a mutated society. Perhaps all societies which were once heavily engaged in sugar culture have developed mutations in some sense of the word, but in Oriente's case the term is particularly apt.
