Portuguese Communist Party

The Portuguese Communist Party was founded in 1921, during the unsettled years of the Portuguese First Republic, with links to the international communist movement that followed the Russian Revolution.¹ The military coup of 1926 and the subsequent Estado Novo made open communist politics illegal. The party rebuilt itself through underground cells, clandestine publications, and workplace organization, especially among industrial workers and agricultural laborers.

Its clandestine structure helped it survive arrests, censorship, and police surveillance by the political police known as the PIDE. The PCP also developed an unusually strong internal culture of discipline and political education. Álvaro Cunhal, who joined the party as a young man and later became its central leader, spent years imprisoned or underground before escaping from Peniche prison in 1960.² During the dictatorship, the party was among the most persistent organized opponents of authoritarian rule.

The Carnation Revolution transformed the Portuguese Communist Party from an illegal opposition organization into a central actor in the democratic transition. The armed forces overthrew the Estado Novo on 25 April 1974, and the PCP was legalized soon afterward.³ Cunhal became minister without portfolio in the provisional government, while communists gained influence in trade unions, workplaces, local administration, and parts of the military movement.

The party supported the nationalization of major banks and industries and backed land occupations and agrarian reform in the Alentejo. These measures formed part of the revolutionary process of 1974–1975, but they also intensified conflict with moderate socialists, conservatives, and foreign governments concerned about Portugal’s alignment. The constitutional settlement of 1976 preserved a pluralist parliamentary democracy, limiting the PCP’s attempt to establish a socialist political order.⁴

Since democratization, the Portuguese Communist Party has remained a significant but usually minority parliamentary force. It won 12.5 percent of the vote in the first constitutional-assembly election in 1975 and subsequently established a durable electoral base in parts of the Alentejo, the Lisbon industrial belt, and the Setúbal Peninsula.⁵ Its parliamentary representation declined over the following decades as the Socialist Party and the Social Democratic Party dominated national government.

The PCP commonly contests legislative elections through the Unitary Democratic Coalition, known in Portuguese as CDU, with the Ecologist Party “The Greens.”⁶ The alliance has also included independent candidates and local civic figures. The party has generally opposed austerity, privatization, military interventions, and European Union policies that it regards as constraining national economic sovereignty. It has supported collective bargaining, stronger public provision, and expanded workers’ rights while maintaining an explicitly communist identity.

The party’s long underground history shaped practices that remain distinctive in contemporary Portuguese politics. The PCP maintains a dense network of local branches, workplace organizations, cultural associations, and annual public events, most famously the Festa do Avante!, a large political and cultural festival held near Lisbon.² Its newspaper, Avante!, originated as an illegal publication and continues as the party’s principal press organ.

A less visible dimension is the party’s continuing connection with trade-union politics through the General Confederation of Portuguese Workers—Intersindical Nacional, commonly called CGTP-IN. The PCP does not formally control the confederation, but communist organizers have historically played a major role in it.⁷ Unlike several western European communist parties, the PCP retained a largely orthodox Marxist-Leninist orientation after the collapse of the Soviet Union, while participating regularly in competitive elections and parliamentary institutions.
