The new regime was intended to be transitory but gradually closed in on itself and became a full dictatorship with the promulgation of the Fifth Institutional Act in 1968. Oppression was not limited to those who resorted to guerrilla tactics to fight the regime, but also reached institutional opponents, artists, journalists and other members of civil society, inside and outside the country through the infamous "Operation Condor". Despite its brutality, like other authoritarian regimes, due to an economic boom, known as an "economic miracle", the regime reached a peak in popularity in the early 1970s.
