Argentina

Historical overview

The territory of present-day Argentina was inhabited by diverse Indigenous peoples, including Mapuche, Guaraní, Diaguita, Qom and Tehuelche communities. These societies maintained distinct languages, economies, political organisations and relationships with neighbouring regions. Spanish colonisation expanded during the sixteenth century, and Buenos Aires became an important port and administrative centre.

The May Revolution of 1810 established a local governing authority in Buenos Aires. Independence was formally declared on 9 July 1816 at the Congress of Tucumán. The following decades were marked by civil wars between centralist and federalist forces, regional political competition and disputes over the organisation of the new state. The Constitution of 1853 established a federal republic, although Buenos Aires joined the constitutional federation only after a period of separation. National ArchivesDuring the late nineteenth century, Argentina experienced major agricultural exports, railway expansion and mass immigration from Europe. Economic growth coincided with the expansion of state territory through military campaigns against Indigenous communities, particularly the so-called Conquest of the Desert in the 1870s and 1880s. These campaigns resulted in land dispossession, killings, displacement and forced labour.

The Sáenz Peña Law of 1912 introduced secret and compulsory voting for male Argentine citizens, contributing to the election of the Radical Civic Union in 1916. Women gained national voting rights in 1947. Juan Domingo Perón became president in 1946, promoting labour rights and social programmes while political polarisation intensified. A military coup removed him in 1955.

Argentina experienced repeated military interventions and unstable civilian governments during the second half of the twentieth century. On 24 March 1976, a military coup established the National Reorganisation Process. The dictatorship carried out systematic state terrorism, including clandestine detention, torture, extrajudicial killing and enforced disappearance. The Mothers and Grandmothers of Plaza de Mayo became internationally recognised human-rights organisations, campaigning for truth about disappeared people and children who had been appropriated by the regime.

The dictatorship ended after the 1982 Falklands/Malvinas War and the return to civilian government. Elections were held on 30 October 1983, and Raúl Alfonsín assumed office in December. The National Commission on the Disappearance of Persons (CONADEP) was established in 1983 and published the Nunca Más report in 1984. In December 1985, the Trial of the Juntas resulted in convictions of senior military leaders. argentina.gob.arArgentina’s subsequent democratic period included economic crises, constitutional reform in 1994, the cancellation and later reversal of some impunity measures, and renewed trials for crimes against humanity. The National Memory Archive preserves CONADEP testimony, judicial records and material from human-rights organisations. Catálogo ANM
