It is also possible to see an escalation in the repressive violence and a decline in respect for legal norms in each of the coups. In particular, whereas the first four coups d'état (1930, 1943, 1955, 1962) were defined as "provisional governments" and acted with the intention of calling democratic elections within a short time period, the two last coups (1966 and 1976) brought to power military dictatorships which were permanent and adhered to the idea of the bureaucratic-authoritarian state, described by Guillermo O'Donnell.
