By the 1970s, nearly a half-century of authoritarian rule weighed on Portugal. The
28 May 1926 coup d'état implemented an authoritarian regime incorporating
social Catholicism and
integralism. In 1933, the regime was renamed the .
António de Oliveira Salazar served as Prime Minister until 1968. Although there are documented cases of some local elections where an independent candidate who was allowed to run did actually win, those were exceedingly rare and the vast majority were
sham elections where the government candidate usually ran unopposed, while the opposition used the limited political freedoms allowed during the brief election period to protest, withdrawing their candidates before the election to deny the regime
political legitimacy. The Estado Novo's political police, the
PIDE (Polícia Internacional e de Defesa do Estado, later the DGS, Direcção-Geral de Segurança and originally the PVDE, Polícia de Vigilância e Defesa do Estado),
persecuted opponents of the regime, who were often tortured, imprisoned or killed. In 1958, General
Humberto Delgado, a former member of the regime, stood against the regime's presidential candidate,
Américo Tomás, and refused to allow his name to be withdrawn. Tomás won the election amidst claims of widespread electoral fraud, and the Salazar government abandoned the practice of popularly electing the president and gave the task to the
National Assembly. Portugal's Estado Novo government remained neutral in the
Second World War, and was initially tolerated by its
NATO post-war partners due to its
anti-communist stance. As the
Cold War developed,
Western Bloc and
Eastern Bloc states vied with each other in supporting
guerrillas in the
Portuguese colonies, leading to the 1961–1974
Portuguese Colonial War. Salazar had a
stroke in 1968, and was replaced as
prime minister by
Marcelo Caetano, who adopted a slogan of "continuous evolution", suggesting reforms, such as a monthly
pension to rural workers who had never contributed to Portugal's
social security. Caetano's Primavera Marcelista (Marcelist Spring) included greater political tolerance, but not a complete
freedom of the press (prior censorship remained in place until April 25, 1974), and was seen as an opportunity for the opposition to gain
concessions from the regime. In 1969, Caetano authorised the country's first democratic labour union movement since the 1920s. However, after the elections of
1969 and
1973, hard-liners in the government and the military pushed back against Caetano, with
political repression against
communists and
anti-colonialists.
Economic conditions The Estado Novo regime's economic policy encouraged the formation of large
conglomerates. The regime maintained a policy of
corporatism which resulted in the placement of much of the economy in the hands of conglomerates including those founded by the families of
António Champalimaud (
Banco Totta & Açores,
Banco Pinto & Sotto Mayor,
Secil,
Cimpor),
José Manuel de Mello (
Companhia União Fabril),
Américo Amorim (
Corticeira Amorim) and the dos Santos family (
Jerónimo Martins). One of the largest was the Companhia União Fabril (CUF), with a wide range of interests including cement, petro and agro chemicals, textiles, beverages, naval and electrical engineering,
insurance, banking, paper, tourism and mining, with branches, plants and projects throughout the Portuguese Empire. Other medium-sized family companies specialised in textiles (such as those in
Covilhã and the northwest), ceramics, porcelain, glass and crystal (such as those in
Alcobaça,
Caldas da Rainha and
Marinha Grande), engineered wood (such as
SONAE, near
Porto), canned fish (
Algarve and the northwest), fishing, food and beverages (liqueurs, beer and
port wine), tourism (in
Estoril,
Cascais,
Sintra and the Algarve) and agriculture (the
Alentejo, known as the
breadbasket of Portugal) by the early-1970s. Rural families engaged in agriculture and forestry. Income from the colonies came from resource extraction, of oil, coffee, cotton, cashews, coconuts, timber, minerals (including diamonds), metals (such as iron and aluminium), bananas, citrus, tea, sisal, beer, cement, fish and other seafood, beef and textiles.
Labour unions were subject to severe restrictions, and
minimum wage laws were not enforced. Starting in the 1960s, the outbreak of colonial wars in Africa set off significant social changes, among them the rapid incorporation of women into the labour market.
Colonial war helicopter in Africa Independence movements began in the African colonies of
Portuguese Mozambique,
Portuguese Congo,
Portuguese Angola, and
Portuguese Guinea. The Salazar and Caetano regimes responded with diverting more and more of Portugal's
budget to colonial administration and
military expenditure, and the country became increasingly
isolated from the rest of the world, facing increasing internal dissent,
arms embargoes and other
international sanctions. By the early-1970s, the
Portuguese military was overstretched and there was no political solution in sight. Although the number of
casualties was relatively small, the war had entered its second decade; Portugal faced criticism from the international community, and was becoming increasingly isolated. In 1973 the UN General Assembly passed a resolution calling for Portugal's immediate withdrawal from Guinea. Atrocities such as the
Wiriyamu Massacre undermined the war's popularity and the government's diplomatic position, although details of the massacre are still disputed. The war became unpopular in Portugal, and the country became increasingly polarised. Thousands of left-wing students and anti-war activists avoided
conscription by
emigrating illegally, primarily to
France and the
United States. Meanwhile, three generations of right-wing militants in Portuguese schools were guided by a
revolutionary nationalism partially influenced by European
neo-fascism, and supported the
Portuguese Empire and an authoritarian regime. The war had a profound impact on the country. The revolutionary
Armed Forces Movement (MFA) began as an attempt to liberate Portugal from the Estado Novo regime and challenge new military laws which were
coming into force. The laws would reduce the military budget and reformulate the Portuguese military. Younger military-academy graduates resented Caetano's programme of commissioning militia officers who completed a brief training course and had served in the colonies' defensive campaigns at the same rank as academy graduates. ==Revolution==
