Colombia

Before the arrival of Europeans, the territory of present-day Colombia was inhabited by a mosaic of indigenous peoples whose settlement reached back several millennia. Among the most prominent were the Muisca of the central Andean highlands, organised into a confederation of chiefdoms around the Bogotá and Tunja plateaus and renowned for their goldwork and salt trade, alongside the Tairona of the Sierra Nevada de Santa Marta, the Quimbaya of the middle Cauca valley, and the Zenú of the Caribbean lowlands. These societies practiced terraced agriculture, long-distance exchange, and sophisticated metallurgy, and their legacy is preserved in archaeological sites such as San Agustín and Tierradentro, whose monumental sculpture predates the classical Muisca period by many centuries.

Spanish contact began in 1499 with coastal expeditions led by Alonso de Ojeda, and permanent settlement followed at Santa Marta in 1525 and Cartagena in 1533. In 1538 Gonzalo Jiménez de Quesada founded Santa Fe de Bogotá after subjugating the Muisca, and the territory was incorporated into the Spanish Empire as the New Kingdom of Granada, governed first as an audiencia under the Viceroyalty of Peru and, from 1717 (and definitively from 1739), as the Viceroyalty of New Granada. Colonial society was organised around encomienda labour, mining, and the Caribbean slave trade routed through Cartagena, with Catholic missions and a creole landed elite consolidating over nearly three centuries of Habsburg and Bourbon rule.

Independence movements gathered force after the Napoleonic crisis in Spain, beginning with the Cry of Independence in Bogotá on 20 July 1810 and culminating in Simón Bolívar's victory at the Battle of Boyacá on 7 August 1819. The resulting state, Gran Colombia, briefly united present-day Colombia, Venezuela, Ecuador, and Panama before dissolving in 1830 into the Republic of New Granada. Through the nineteenth century the country alternated between centralist and federalist constitutions, fought repeated civil wars between Liberals and Conservatives, and adopted its present name, the Republic of Colombia, under the centralist constitution of 1886. Panama separated in 1903 with United States backing during construction of the canal.

The twentieth century opened under the long Conservative hegemony, gave way to a Liberal reformist period in the 1930s, and was scarred by the assassination of Jorge Eliécer Gaitán in 1948, which triggered the violent partisan conflict known as La Violencia. A short military government under Gustavo Rojas Pinilla from 1953 was followed by the National Front power-sharing pact between Liberals and Conservatives from 1958 to 1974. From the 1960s onward, leftist insurgencies including the FARC and the ELN, right-wing paramilitaries, and powerful drug-trafficking organisations sustained an internal armed conflict that overlapped with the Cold War and the United States led counter-narcotics effort.

A new constitution promulgated in 1991 broadened civil rights, recognised indigenous and Afro-Colombian communities, and reorganised the judiciary. Successive governments pursued security policies through the 2000s and negotiated a peace accord with the FARC in 2016 under President Juan Manuel Santos, while talks with the ELN have continued intermittently. In 2022 Gustavo Petro became the country's first left-wing president. Colombia today is a unitary presidential republic with a directly elected president, a bicameral Congress composed of the Senate and the House of Representatives, and a constitutional court, organised into thirty-two departments and the Capital District of Bogotá.
