Colombia

From Fifty Years of War to an Uncertain Peace

Colombia is the only country in South America with coastlines on both the Pacific Ocean and the Caribbean Sea. It is also the only major country in the Western Hemisphere that has fought a continuous internal armed conflict for more than half a century, during which it simultaneously maintained democratic elections, a functioning judiciary, and a growing economy. These apparent contradictions — democracy amid war, economic growth amid mass displacement, institutional resilience amid state fragility — define Colombia’s peculiar position in Latin American geopolitics. The 2016 peace agreement with the FARC guerrillas was hailed as a historic achievement and received the Nobel Peace Prize; seven years later, the country faces FARC dissident groups, an emboldened ELN, expanding criminal networks, and a left-wing president pursuing “Total Peace” through simultaneous negotiations whose prospects remain deeply uncertain.

Geographic Position

Colombia occupies the northwestern corner of South America, where the continent narrows toward the Isthmus of Panama. It is the only South American country bordering both the Pacific and Caribbean — 3,208 kilometres of combined coastline — and its 6,342 kilometres of land borders touch Venezuela to the east, Ecuador and Peru to the south, Brazil to the southeast, and Panama to the northwest. This geographic position makes Colombia the literal bridge between North and South America and between the Atlantic and Pacific basins.

The interior geography is dramatically varied: the Andes split into three cordilleras running north-south through the country; the Caribbean lowlands in the north; the Pacific jungle coast in the west (Chocó, one of the world’s rainiest places); the vast eastern llanos (grasslands) and Amazonian jungle occupying roughly half the national territory. This geographic complexity has historically prevented the Colombian state from exercising effective authority across all its territory — the Andean cities govern themselves reasonably well, while the Pacific coast, the llanos, and the Amazon have been perpetual zones of state absence, fertile ground for guerrilla movements and criminal networks.

The Pacific coast’s geographic and demographic marginality is a persistent political problem. Afro-Colombian communities who make up the majority in many Pacific departments have faced the highest rates of displacement, violence, and institutional neglect. The coca-growing regions of Putumayo, Norte de Santander, and Catatumbo lie precisely in the zones where state presence has been weakest — creating the convergence of guerrilla activity, coca cultivation, and civilian victimisation that has defined Colombian conflict geography.

Historical Development

Spanish colonisation established Santa Fe de Bogotá in 1538 as the capital of the New Kingdom of Granada. Colombia’s colonial society was marked by sharp hierarchies of race, land ownership, and regional identity that persist in attenuated form today: the Liberal-Conservative divide of the nineteenth and twentieth centuries, the persistence of caciquismo (regional bossism), and the failure of land reform that feeds rural grievances all trace to colonial foundations.

Independence came in 1810-1819 under Simón Bolívar’s campaigns. The new state was initially part of Gran Colombia (which also included modern Venezuela, Ecuador, and Panama); fragmentation followed quickly. Panama, notably, separated from Colombia in 1903 with American assistance — US support for Panamanian separatists served Washington’s interest in securing the canal treaty, and the episode left a lasting Colombian ambivalence about American reliability as a partner.

The nineteenth century was characterised by endemic civil conflict between Liberal and Conservative factions that killed hundreds of thousands in the War of a Thousand Days (1899-1902) alone. The coffee economy that grew from the 1880s onward created the basis for Colombian export-led development and a substantial rural smallholder class; but the land distribution concentrated in large haciendas drove persistent peasant grievances that the political system failed to address.

La Violencia — the civil conflict between Liberals and Conservatives that erupted in 1948 following the assassination of Liberal leader Jorge Eliécer Gaitán — killed an estimated 200,000-300,000 people between 1948 and 1958. Its formal end came through the National Front agreement, in which the Liberal and Conservative parties agreed to share the presidency in alternating four-year terms from 1958 to 1974. The agreement ended partisan killing but at the cost of excluding other political forces and locking in an oligarchic arrangement that left structural grievances unaddressed — precisely the conditions from which the guerrilla movements would emerge.

The Conflict: FARC, ELN, and the Paramilitaries

The FARC (Fuerzas Armadas Revolucionarias de Colombia) was founded in 1964 by peasant communists, many of them veterans of La Violencia who had established self-defence communities in the cordilleras. The ideological framework was Marxist-Leninist; the social base was the rural poor and coca-growing peasantry; the financing came increasingly from extortion, kidnapping, and, from the 1980s onward, from taxing coca cultivation and cocaine processing. At peak strength in the early 2000s, the FARC fielded roughly 20,000 combatants, controlled large swathes of rural territory, and had the capacity to threaten Bogotá’s periphery and assassinate presidential candidates.

The ELN (Ejército de Liberación Nacional), founded in 1964 with Cuban inspiration, adopted a theology of liberation variant of Marxism under the influence of priest-guerrilla Camilo Torres. Smaller than the FARC and more focused on oil infrastructure sabotage and kidnapping in the northeastern departments near Venezuela, the ELN survived the peace process with the FARC as the remaining major guerrilla organisation.

The paramilitary movement — the AUC (Autodefensas Unidas de Colombia) — emerged partly as a landowner, partly as a state-adjacent response to FARC kidnapping and extortion, and became one of the primary perpetrators of massacres against civilian communities suspected of guerrilla sympathy. The AUC demobilised under a 2003-2006 agreement, but its networks fragmented into criminal successor organisations (the BACRIM — bandas criminales) that persist as the Clan del Golfo and other organisations.

The conflict’s civilian toll is staggering: over 220,000 killed (the majority civilians, not combatants), approximately 8 million internally displaced persons (one of the world’s largest internal displacement situations), over 80,000 persons forcibly disappeared, and tens of thousands of kidnapping victims. These are not historical statistics; many of the displaced have not returned, the disappeared remain unaccounted for, and the communities most affected continue to bear the consequences.

The Drug Dimension

Colombia has been the world’s dominant cocaine producer for most of the past four decades, producing an estimated 80-90 percent of the cocaine consumed in the United States and substantial shares of European supply. The cocaine economy is estimated to generate between $3-8 billion annually for Colombian-based actors — figures difficult to establish precisely because the industry is clandestine. Coca cultivation is concentrated in the Pacific lowlands (Nariño, Cauca), the Orinoco piedmont (Meta, Guaviare), the Catatumbo region bordering Venezuela, and Putumayo.

The drug economy has reshaped Colombian politics in ways that cannot be separated from the conflict analysis. The Medellín cartel under Pablo Escobar in the 1980s waged a campaign of terrorism against the Colombian state — assassinating justice ministers, newspaper editors, presidential candidates, and hundreds of police officers — that demonstrated the state’s potential vulnerability to narco-violence. The Cali cartel that succeeded it was subtler, using corruption rather than frontal violence. The decapitation of both cartels in the 1990s did not reduce cocaine production; it fragmented supply chains and gave the FARC and paramilitaries larger roles in the cocaine economy.

The US-Colombia drug relationship is the most consequential bilateral dimension of the conflict. American cocaine demand created the economic incentive; American drug war strategy created the Plan Colombia framework that, paradoxically, was the principal instrument of FARC military defeat; and American counter-narcotics pressure has consistently shaped Colombian domestic political choices. The fundamental tension — US demand generates the market, US supply-side pressure falls on Colombian producers and peasants — has never been honestly confronted in bilateral drug policy.

Plan Colombia

Plan Colombia (2000-2016) was the largest US security assistance programme in the Western Hemisphere since the Cold War — approximately $10 billion in aid over sixteen years, predominantly military and police assistance. Its centrepiece was aerial coca eradication (fumigation with glyphosate), which was widely unpopular with rural communities and had mixed effectiveness at reducing net coca cultivation. Its more consequential achievement was the transformation of the Colombian military from an institution unable to project force into contested rural territories into a capable counterinsurgency force.

Between 2002 and 2010, under Presidents Uribe’s “Democratic Security” policy (supported by US training, intelligence, and equipment), the FARC was degraded from roughly 20,000 fighters to under 8,000. Key leaders were killed — including the FARC secretariat’s senior military commander Mono Jojoy in 2010 and founder Alfonso Cano in 2011. The FARC’s urban networks were dismantled; its capacity to mount large-unit attacks was broken; its access to population centres was severed. The state’s military advantage became so overwhelming that the FARC leadership, meeting in Havana with Cuban mediation and Norwegian facilitation, concluded that continued war was strategically futile.

The 2016 Peace Agreement

The Santos-FARC agreement, signed in September 2016 (revised following a narrow “No” referendum result and re-signed in November 2016), was a comprehensive negotiated settlement covering rural reform, political participation, illicit crop substitution, transitional justice, victims’ rights, and disarmament. President Juan Manuel Santos received the Nobel Peace Prize for his leadership of the process.

The accord’s central mechanisms included: - The FARC’s disarmament and demobilisation, with UN verification, leaving over 7,000 combatants to enter civilian life - A Special Jurisdiction for Peace (JEP) — a transitional justice tribunal that offered reduced sentences for FARC commanders who acknowledged responsibility and provided truth - Rural reform provisions — land formalisation, rural development investment — designed to address the agrarian grievances that had fuelled the conflict - FARC political participation, with guaranteed congressional seats for a period

Implementation has been deeply uneven. The disarmament process largely succeeded — over 7,000 combatants demobilised and weapons were turned over to the UN. But the political and rural reform pillars have lagged badly under the Duque government (2018-2022), which was ideologically hostile to the accord. More seriously, a significant fraction of FARC combatants — estimated at 3,000-5,000 fighters — rejected the peace deal and reconstituted armed organisations, the “disidencias” (FARC dissidents), which have expanded their presence in strategic drug and mining corridors.

Gustavo Petro and “Total Peace”

Gustavo Petro’s election in June 2022 as Colombia’s first left-wing president was historically significant. Petro, a former member of the M-19 urban guerrilla movement (which demobilised in 1990 and became a political party), had been mayor of Bogotá and a senator before winning the presidency on his third attempt. His vice president, Francia Márquez, an Afro-Colombian environmental activist from Cauca, brought historic representation for the communities most affected by conflict and displacement.

Petro’s “Total Peace” (Paz Total) policy aims to negotiate simultaneously with the ELN, FARC dissident groups, and criminal organisations. The approach reflects a genuine belief that security-led counter-narcotics and counter-insurgency strategies have failed — coca production reached record levels under Duque despite military pressure — and that only negotiated social transformation can address the structural drivers of violence. Critics, including the Colombian right and elements of the US government, argue that the approach rewards armed groups with negotiating status and ceasefire protection that allows them to consolidate territorial control.

Progress has been fitful. ELN negotiations in Havana have produced ceasefire agreements, subsequently broken by the ELN, and resumed negotiations. FARC dissident talks have been complicated by the fragmentation of dissident groups and the criminal interests that leadership figures have in continuing drug trafficking rather than reaching a settlement. Clan del Golfo and other criminal organisations present yet another category: pure criminal enterprises that lack the political objectives that make negotiated settlements conceivable.

The Venezuela Relationship

The Colombia-Venezuela relationship is the most geopolitically significant bilateral relationship in South America. The 2,219-kilometre shared border is the most economically active in the Andean region when it functions; when it is closed — as it was from 2015 to 2022 under Maduro’s border closure — it generates smuggling, migration pressure, and security complications that affect both countries.

Colombia hosts approximately 2.9 million Venezuelan migrants and refugees — the largest Venezuelan diaspora anywhere. Their presence has strained Colombian public services, generated anti-Venezuelan sentiment in receiving cities, and created a politically sensitive constituency that Petro, unlike his predecessors, has embraced as a permanent part of Colombian society. Colombia’s decision to grant Temporary Protected Status to Venezuelans — offering a path to legal residency and work authorisation — was an act of regional solidarity that has generated modest international recognition but substantial domestic fiscal cost.

Petro reopened the border with Venezuela in September 2022, restoring trade flows that benefit border communities on both sides. He maintains a cordial relationship with Maduro that is primarily instrumental: Colombian business interests need access to Venezuelan markets, and Petro needs Maduro’s cooperation on security matters (the ELN has significant rear bases on the Venezuelan side of the border, with Maduro’s tacit acquiescence). The relationship has irritated Washington, which views Petro’s engagement with Maduro as legitimising a dictatorship.

US Relationship

The US-Colombia relationship has been Washington’s most important in Latin America for two decades — a product of Plan Colombia, the drug war, the FARC peace process, and Colombia’s consistent alignment with US positions in multilateral forums. Colombia has been designated a “Major Non-NATO Ally,” hosts US military trainers and special operations advisors, and has participated in US-led military exercises globally.

The Petro presidency has introduced friction without fundamental rupture. Petro suspended aerial coca eradication, citing its effects on rural communities and the environment — a decision that the US counter-narcotics establishment found unacceptable. He has pursued independent positions on Venezuela and Cuba, engaged with governments that Washington considers adversaries, and championed a drug legalisation framework in multilateral forums that directly challenges the UN drug control conventions that US policy has traditionally defended.

Yet the structural depth of the relationship — military cooperation, trade under the US-Colombia Free Trade Agreement, intelligence sharing, counter-terrorism cooperation — has proved durable enough to absorb Petro’s policy heterodoxy. The US needs Colombia as a partner in the region; Colombia needs US market access and security assistance. The relationship continues, with more friction than before but without a fundamental break.

Economic Story

Colombia’s economy is the third-largest in Latin America (after Brazil and Mexico), with GDP of approximately $350 billion and per capita income around $7,000. The economic transformation of the past two decades has been significant: the security improvements of the 2000s enabled investment, tourism growth, and infrastructure development that had been impossible while the FARC threatened major cities. Medellín — once synonymous globally with Pablo Escobar’s violence — has reinvented itself as an urban innovation hub and tourist destination.

The export base combines oil and coal (around 50 percent of exports), coffee (Colombia’s most iconic export and the basis for a globally recognised brand), cut flowers (Colombia is the world’s second-largest flower exporter, primarily to the US market), and an increasingly significant services sector. Bogotá has developed a substantial financial services and technology industry that serves the broader Andean region. Offshore oil production in the Caribbean and Pacific has expanded the hydrocarbon portfolio.

The informal economy remains very large — estimated at 30-40 percent of GDP — reflecting the historical state absence in rural areas and the integration of drug economy proceeds into the legitimate financial system through money laundering. Land distribution remains among the most unequal in the world; the Gini coefficient for land ownership is one of the highest anywhere, and the rural inequality it represents feeds the structural grievances that underpin recurring cycles of conflict.

Regional Role

Colombia occupies a distinctive regional niche: a democracy that has sustained functioning institutions through fifty years of internal war, that has managed (imperfectly) a transition from conflict under both right-wing and now left-wing leadership, and that has maintained consistent external alignment with the democratic community even as its internal politics have polarised sharply. This gives Colombia moral authority in regional discussions about democracy, human rights, and the Venezuela crisis that it uses — under Petro — in an unexpected direction, arguing for dialogue rather than isolation.

Petro has also positioned Colombia as a voice for a new approach to drug policy, arguing that the fifty-year “War on Drugs” has failed on its own terms and that consuming countries need to take responsibility for demand reduction rather than exporting the violence of supply-side suppression to producing countries. The argument has resonance across Latin America, where anti-drug strategies have been seen as imposing costs on the region for the benefit of US domestic politics.

Security Challenges

Despite the 2016 peace agreement, Colombia’s security environment in 2026 remains troubled. FARC dissident groups — particularly the Estado Mayor Central (EMC) under Ivan Mordisco — have expanded significantly, controlling coca and gold corridors in Putumayo, Caquetá, and Cauca. The ELN controls significant territory in Norte de Santander, Chocó, and Arauca. The Clan del Golfo dominates drug trafficking routes in the Caribbean coast region. Overall homicide rates, while lower than the 2000s peak, remain higher than regional peers.

The Catatumbo crisis of January 2025 — in which a brutal ELN offensive killed dozens of civilians and displaced over 32,000 people — prompted Petro to suspend ELN peace talks, military emergency declarations, and a collapse of the ceasefire framework. The episode illustrated the central contradiction of “Total Peace”: negotiating with armed groups that have incentives to continue fighting, control territory for criminal revenue, and periodically use violence to improve their bargaining position.

Strategic Significance

Colombia’s geopolitical significance operates on several levels. Its coca production makes it central to the global cocaine market and to US drug policy in a way that no other country is. Its border with Venezuela makes it the principal transit country for Venezuelan displacement and the key bilateral relationship in South American security. Its institutions — a Supreme Court that functions, electoral authorities that are respected, a Constitutional Court that has struck down government measures — provide a regional model of imperfect but genuine democratic governance under stress. And its role as the US’s closest regional ally means that Colombian foreign policy orientations have outsized significance for US hemispheric strategy.

Future Outlook

Colombia’s near-term future is defined by the outcome of the Petro peace strategy. If Total Peace negotiations produce durable agreements with the ELN and manageable settlements with dissident FARC groups, the country could build on the 2016 peace architecture to reduce violence, allow rural development investment, and begin addressing the structural inequalities that perpetuate the conflict cycle. If the negotiations collapse — as the Catatumbo episode suggested was possible — Colombia faces the prospect of resuming intensive military operations against armed groups that have used ceasefire periods to rearm and expand.

The presidential election of 2026 will be consequential. If the right wins, it will likely abandon the “Total Peace” framework and return to a security-first counter-narcotics model backed by the US; if a centrist or leftist government continues, the negotiation framework will be maintained but faces the same structural obstacles. Either way, coca cultivation — driven by global demand and the poverty of rural growers — will remain the structural challenge that no Colombian government has yet solved.
