Sofia Ferreira

Sofia de Oliveira Ferreira was born on 1 May 1922 in Alhandra in the Portuguese municipality of Vila Franca de Xira. A daughter of agricultural workers she was a sister of Georgette Ferreira and Mercedes Ferreira who, like Sofia, both became members of the Communist Party. By the age of ten she was working on farms together with her mother. At the age of twelve, Ferreira went to live with her godparents in Lisbon, doing housework and taking care of the elderly. It was only at this stage that she learnt to read, with help from a neighbour, who also taught her basic mathematics skills. At the age of 20, she began to serve as a domestic servant in a private home.^[1]

Ferreira joined the Communist Party (PCP) in 1945. Although older than Georgette and Mercedes, she was the last to join the Party. In 1946, she was selected by the PCP for clandestine work in Figueira da Foz. For two years she lived and worked in an isolated house on a farm in which there was a printing press for the publication, O Militante, a magazine for PCP members, together with other communist party propaganda materials. She was then given the role of living in a support house in Luso for the PCP Secretariat, pretending to be the wife of the de facto PCP leader Álvaro Cunhal, and using the pseudonym "Elvira". In this house, on 25 March 1949, she, Cunhal, and Militão Ribeiro were arrested by the PIDE, the Estado Novo's secret police.^{[1][2][3][4][5]}

Ferreira was subjected to long sessions of interrogation, with torture, in the PIDE headquarters in Porto. Refusing to make any statements or sign records of the interrogations, she was then held in complete isolation for six months, with visits only allowed every 15 days and for just 15 minutes. In May 1950 she was sentenced to 18 months in prison, a sentence that was later extended, leading to her eventual release in February 1953. She then moved to Porto, involving herself in local organization of the PCP. In 1957, although she did not participate in person at the illegal 5th Congress of the PCP, she was elected as an alternate member of the Central Committee of the Portuguese Communist Party.^[1][4][5][6]
