ABSTRACT
The great economic transformations that took place in Brazil between 1930 and 1961 were accompanied by profound social transformations. This chapter attempts to describe the first steps of Brazilian society on its way to pluralization, to the diversification of its social classes, giving special emphasis to the process that gave rise to a class of middle managers. Industrialization modified standards of behavior, interrupted and transformed traditional economic relations, and provided a base for deep social changes. New classes arose; Brazil developed and left many of its feudal characteristics behind. In addition to urbanization and the formation of a new class of industrial workers, there were also significant social changes among rural workers. The transformations in the middle class during the industrial revolution in Brazil were also crucial. Brazil's rapid social development during the 1930s, 1940s, and 1950s was characterized by overlapping phases and consequently by hybridism in structure and social institutions.
