Colombia's population in 2024 stands at approximately 52 million people distributed across topographies that include three Andean cordilleras, Caribbean and Pacific coastlines, Amazon rainforest territories, and eastern grassland plains called Los Llanos. The country contains 87 distinct indigenous groups speaking 65 indigenous languages alongside Spanish, Palenquero, and the English-based creole of San Andrés and Providencia. Census classifications divide the population roughly as 49 percent mestizo, 37 percent white, 10.6 percent Afro-Colombian, and 3.4 percent indigenous, though these categories flatten considerable internal variation and self-identification practices that change across generations and geographic contexts. Regional identity often supersedes national identity in daily conversation. A person from Cali will identify as Caleño first, a person from the Caribbean coast as Costeño, someone from Medellín as Paisa. These regional identities carry distinct Spanish dialects, food traditions, musical preferences, and historical grievances that have shaped political alignments since independence.
The Muisca confederations controlled the high plains around present-day Bogotá and Tunja when Spanish expeditions arrived in 1537 under Gonzalo Jiménez de Quesada. The Muisca practiced terrace agriculture at altitudes between 2,000 and 3,000 meters, traded emeralds and salt across wide networks, and organized themselves into two main federations led by the Zipa based at Bacatá and the Zaque at Hunza. Spanish chroniclers estimated the Muisca population between 300,000 and 2 million before contact, though no consensus figure exists. The Spanish introduced smallpox, measles, and typhus, which reduced indigenous populations across the region by approximately 90 percent within 80 years of contact according to demographic reconstructions by historian Noble David Cook. The Muisca political structure collapsed between 1537 and 1540. The Spanish established Santa Fe de Bogotá in 1538 on the site of the Muisca settlement Bacatá. Gold objects taken from Muisca tombs and ceremonial sites fed the El Dorado legend that motivated Spanish exploration throughout northern South America for the next century. The Museo del Oro in Bogotá today holds approximately 34,000 gold objects, the largest pre-Columbian gold collection globally, with substantial Muisca pieces alongside Calima, Quimbaya, Tairona, and Zenú goldwork.
Spanish colonial administration organized the territory as the Viceroyalty of New Granada in 1717 with jurisdiction over present-day Colombia, Venezuela, Ecuador, and Panama. Cartagena became the primary slave port on the South American mainland. Between 1533 and 1810, approximately 200,000 enslaved Africans arrived at Cartagena, though total imports may reach 1 million when contraband trade is included, according to research by historian María Cristina Navarrete. Enslaved populations worked gold mines in Antioquia and Chocó, haciendas in the Cauca Valley, and plantations along both coasts. Palenque de San Basilio, founded by escaped enslaved people in the 17th century in the hills south of Cartagena, maintained autonomy and developed Palenquero, a Spanish-based creole language with Kikongo and Portuguese influences still spoken by approximately 3,000 people. San Basilio de Palenque received UNESCO recognition in 2005 as a Masterpiece of the Oral and Intangible Heritage of Humanity. Colombia abolished slavery in 1851, two years before Ecuador, 37 years before Brazil. Afro-Colombian populations today concentrate in the Pacific coast departments of Chocó, Valle del Cauca, and Cauca, the Caribbean departments of Bolívar and Atlántico, and the San Andrés Archipelago. The 2018 census recorded 2.98 million people self-identifying as Afro-Colombian or Raizal, approximately 9.34 percent of the total population, though Afro-Colombian advocacy organizations argue the actual percentage reaches 20 percent when accounting for census undercounting in remote areas.
Independence movements accelerated after Napoleon's invasion of Spain in 1808 created a legitimacy crisis for colonial administration. Bogotá declared independence on July 20, 1810, a date now celebrated as Independence Day, though Spanish forces recaptured the city in 1816 under General Pablo Morillo, who executed independence leaders including Policarpa Salavarrieta, an intelligence operative for republican forces arrested and shot in Bogotá's main plaza on November 14, 1817 at age 23. Simón Bolívar, who had fought unsuccessful campaigns in Venezuela and New Granada, crossed the Andes from the Venezuelan plains with 2,500 troops including the British Legion composed of Napoleonic War veterans. Bolívar's forces defeated Spanish troops at the Battle of Boyacá on August 7, 1819 near Tunja, a victory that secured Bogotá and opened the route to Venezuela and Ecuador. The Republic of Gran Colombia formed in 1819 united Venezuela, New Granada, and later Ecuador under Bolívar's presidency with Francisco de Paula Santander as vice president. Regional tensions between centralists and federalists, economic interests of coastal merchants versus highland landowners, and personal rivalries between Bolívar and Santander fractured the union. Venezuela seceded in 1829. Ecuador followed in 1830. Bolívar died of tuberculosis in Santa Marta on December 17, 1830 at age 47 while attempting to reach exile in Europe. His final residence, the Quinta de San Pedro Alejandrino, operates as a museum five kilometers outside Santa Marta. The remaining territory became the Republic of New Granada, which adopted the name Colombia in 1863.
Political violence between Liberal and Conservative parties defined Colombian history from the 1840s through the late 20th century. The parties formed around centralist versus federalist positions, with Conservatives favoring strong central government and Catholic Church influence while Liberals advocated federalism and secular institutions. The Thousand Days War from 1899 to 1902 killed approximately 100,000 people, roughly 2.5 percent of Colombia's population at the time. The war weakened the government's control over Panama, facilitating the US-supported Panamanian independence in 1903 and subsequent canal construction. Liberal politician Jorge Eliécer Gaitán emerged in the 1940s advocating land reform and labor rights. His assassination in Bogotá on April 9, 1948 sparked riots called El Bogotazo that destroyed the city center and left approximately 3,000 dead in Bogotá alone. El Bogotazo initiated La Violencia, a period of partisan warfare between Liberal and Conservative militias that killed between 200,000 and 300,000 people from 1948 to 1958 primarily in rural areas of Tolima, Valle del Cauca, Caldas, and Cundinamarca departments. The National Front agreement in 1958 established power-sharing where the presidency alternated between parties every four years until 1974, ending the most intense partisan violence but excluding alternative political movements from formal participation.
Gabriel García Márquez received the Nobel Prize in Literature in 1982 for novels including One Hundred Years of Solitude, published in 1967. García Márquez was born in Aracataca, a town in Magdalena department, on March 6, 1927. He worked as a journalist in Barranquilla, Cartagena, and Bogotá before leaving Colombia in 1955, living primarily in Mexico City and Paris while maintaining a house in Cartagena. His fiction drew explicitly on Colombian geography, Colombian violence, and Caribbean coastal culture. Macondo, the fictional town at the center of One Hundred Years of Solitude, derives from landscape and social patterns around Aracataca during the banana boom of the 1910s and 1920s when United Fruit Company operations dominated Magdalena department. García Márquez died in Mexico City on April 17, 2014. His ashes were divided between Mexico City and Cartagena. One Hundred Years of Solitude has sold more than 50 million copies in 46 languages as of 2024.
