Portugal suffered a military coup in 1926, and in 1932 the military endorsed Antonio de Oliveira Salazar as civilian head of state. Strongly influenced by Mussolini, he presided over a rightwing dictatorial regime embracing his ideology of the ‘New State’. Salazar was officially Prime Minister from 1932 to 1968. The regime suppressed all forms of left wing opposition, relying on the PIDE political police, allowed one political ‘party’, and created official trade unions. Freedom of speech and civil liberties were denied, and strikes banned. The regime held elections for the ceremonial post of President, on a franchise restricted by literacy (over one third of adults were illiterate as late as the 1960s) and property qualifications. However, when General Delgado ran against the official candidate in 1958, this limited opening for dissent was cancelled. In 1968, Salazar was succeeded by Marcello Caetano, who made some moves towards liberalization, but did not change the basic nature of the regime.
There were indications of dissent under Salazar, for example illegal strikes. The banned Communist Party maintained an underground presence, and there were also some manifestations of liberal dissent, but the major, indirect, expression of civilian resistance was mass (usually illegal) emigration in search of jobs and to escape the draft. Ultimately, the clearest signs of opposition emerged within the armed forces in reaction to Portugal’s colonial wars in Africa from 1961, wars that engaged a high proportion of the troops in unwinnable conflicts, and drained the country’s resources. ‘People power’ in Portugal followed the coup of April 1974 which enjoyed immense popular support, expressed by the carnations put in the gun barrels of the soldiers. Portugal entered a period of mass mobilization and expression of radical ideas in 1974-75.
