PIDE [SEP] dissolved or abolished
from the merger of two former agencies, the Portuguese International Police and the Political and Social Defense Police. The PVDE was transformed into the PIDE in 1945. PIDE was itself transformed into the Directorate-General of Security or DGS in 1968. After the 25 April 1974 Carnation Revolution, DGS was disbanded in Portugal, but continued to exist transitionally in the Portuguese overseas territories as the Military Information Police or PIM, being finally completely disbanded in 1975.
Although the acronym PIDE was only formally used from 1945 to 1969, the
Oliveira Salazar. In 1968, under Salazar's successor Marcello Caetano, PIDE was renamed the "Direcção Geral de Segurança" (DGS, Directorate General of Security) and underwent some reform. Following a coup by the Portuguese military in 1974 the agency was immediately abolished due to the abhorrence felt for the PIDE/DGS as a tool of the authoritarian regime.
Because of the memory of the abuses of the PIDE/DGS in supporting the regime the establishment of a new civilian intelligence agency was delayed for more than a decade
