Chile

Historical overview

Before Spanish colonisation, the territory of present-day Chile was home to many Indigenous peoples, including Mapuche, Aymara, Atacameño, Diaguita, Rapa Nui and other communities. The Inca Empire extended its influence into northern and central Chile, while the Mapuche maintained significant autonomy and resisted Spanish conquest.

Spanish forces established Santiago in 1541. Colonial Chile formed part of the Viceroyalty of Peru until the establishment of the Captaincy General of Chile. Independence movements developed during the Napoleonic crisis in Spain. The First Government Junta was established in Santiago in 1810, and Chile’s independence was consolidated following the Battle of Maipú in 1818. Archivo NacionalThe nineteenth century involved state-building, constitutional experimentation, territorial expansion and conflict. The War of the Pacific (1879–83) resulted in Chile’s acquisition of territories from Peru and Bolivia, including areas rich in nitrate deposits. The annexation and occupation of Mapuche lands during the late nineteenth century profoundly affected Indigenous communities.

The Constitution of 1925 strengthened presidential government and separated church and state. Chile experienced political polarisation and economic change throughout the twentieth century. Salvador Allende was elected president in 1970, leading a coalition that pursued socialist reforms through constitutional institutions. On 11 September 1973, the armed forces led by General Augusto Pinochet overthrew his government in a coup. Allende died during the attack on the presidential palace.

The military dictatorship from 1973 to 1990 involved systematic human-rights violations, including executions, enforced disappearances, torture, exile and censorship. The National Truth and Reconciliation Commission, commonly called the Rettig Commission, investigated violations resulting in death or disappearance. Its report, delivered in February 1991, documented thousands of complaints and identified recognised victims. The later Valech Commission received testimony from more than 35,000 people who reported political imprisonment and torture. Ministerio de Justicia y Derechos HumanosThe 1988 plebiscite rejected the continuation of Pinochet’s presidency, opening the way to democratic elections in 1989 and the restoration of civilian government in March 1990. The Constitution of 1980 remained in force, although it was amended substantially in 1989 and again in 2005. The transition did not immediately resolve questions of military accountability, constitutional legitimacy and social inequality.

In 2019, widespread protests over inequality, public services and the political system led to an agreement to begin a constitutional replacement process. A constitutional convention produced a draft in 2022, which voters rejected. A second constitutional proposal was also rejected in 2023. These events demonstrate the continuing importance of constitutional debate in Chilean democracy.
