2007. Brazilian society underwent two cycles in the twentieth century, followed, with a gap, by the respective political coalition. Between the beginning of the century and 1964, the first society cycle, "Nação e Desenvolvimento", corresponded at state level by the National-Developmentalist political pact (1930-1984). The second , "Democracia e Justiça Social", begins in the late 1960s and gets exhausted in middle 2000s. It correspond to two political coalitions: first, between 1977 and 1987, the 1977 Popular-Democratic Pact, that achieves democratic transition and political power in 1985 but collapses two years later it follows a political vacuum and, from 1991 to the present, we have the Liberal-Dependent Pact precariously combined with the democratic and social ideas - and no real economic development.
