Brazil’s conflict history begins with Portuguese conquest, which joined a vast territory through violence against Indigenous peoples and the forced labour of enslaved Africans. Slavery was the country’s central formative process: Brazil became the largest and most enduring slave society in the Americas, and its plantation order concentrated land, wealth, and political power long after abolition. Independence preserved this hierarchy within an empire, while the Paraguayan War made Brazil the dominant military power in the River Plate basin and accelerated both national state-building and the crisis of slavery. Brazil’s regional influence thus rested partly on institutions and revenues forged within a slaveholding empire. The military coup of 1964 exposed a later consequence of this unequal political order, replacing fragile democracy with two decades of authoritarian rule. Its aftermath left Brazil confronting the durable links between racial inequality, concentrated power, and democratic instability.
Throughout 2025, Brazil recorded no state-based armed conflict in UCDP/PRIO data, but organized criminal violence persisted through turf wars among factions such as Comando Vermelho and the PCC and one-sided killings of civilians. UCDP recorded 619 battle-related deaths, including 117 civilians.
The World Map of Conflict uses two complementary datasets from the Uppsala Conflict Data Program (UCDP) to visualise conflict per country.
The colour coding of the overview base map is derived from the UCDP Georeferenced Event Dataset (GED), which contains fully verified conflict data aggregated at the country level. UCDP publishes the GED annually (typically May–June of the following year) to allow careful validation of every recorded event.
The map on this country page draws from the UCDP Candidate Events Dataset (CED), which includes the most recent reported events and provides a near-real-time overview of conflict developments. Because these events are still under verification, the data should be considered preliminary.
Historical Lenses
To understand Brazil’s conflict history, it is first important to understand what kind of country it is. Historians often explain the same country in different ways depending on what they believe are the main forces driving history. Each historical lens below offers a different, evidence-based interpretation of the country’s development.
The interpretation most widely accepted by historians, based on mainstream historical research and university scholarship. It reflects broad areas of agreement while acknowledging where historians disagree.
Brazil occupies the eastern half of South America, a landmass larger than the contiguous United States, stretching from the Amazon basin in the north to subtropical plains in the south, populated today by roughly 213 million people descended from Indigenous peoples, Portuguese colonizers, enslaved Africans, and successive waves of European, Middle Eastern, and Asian immigration. The mainstream historical account, most fully set out by Boris Fausto, treats Brazil’s development as a long, largely continuous process of territorial and demographic expansion under a single colonial and then national administration — in contrast to Spanish America’s fragmentation into more than a dozen republics. Portugal’s decision to rule Brazil as one colony, and the accident of the royal family’s flight to Rio de Janeiro in 1808 ahead of Napoleon’s armies, gave the territory a unified administrative core that its neighbors lacked. Independence in 1822 came not through revolutionary rupture but through a Portuguese prince, Pedro I, declaring the colony a separate empire under his own crown — a transition consensus historians read as a compromise that preserved elite continuity, kept slavery intact, and postponed rather than resolved the deeper structural questions of who would count as a citizen of the new nation.
Boris Fausto, A Concise History of Brazil (Cambridge University Press, 1999)
Consensus historians mark four thresholds that reorganized Brazil’s structure. First, the sugar economy of the Northeast (1530s–1700s) imported enslaved Africans on a scale that made Brazil the largest single destination of the Atlantic slave trade — more than four million people, roughly ten times the number brought to the United States — and set a labor system that outlasted the sugar boom itself. Second, the 1808 transfer of the Portuguese court to Rio de Janeiro, fleeing Napoleon, elevated a colony to the functional seat of empire and normalized the idea of Brazil governing itself. Third, abolition in 1888 — the last in the Western Hemisphere — ended legal slavery without land reform or political inclusion for the formerly enslaved, a gap historians treat as the origin of Brazil’s enduring racial and regional inequality. Fourth, the 1964–1985 military dictatorship, installed after a coup against elected president João Goulart, industrialized the economy under authoritarian rule before yielding to a negotiated return to democracy and the 1988 constitution, still in force, which extended new social and political rights while leaving the deep inequalities of land and income largely untouched.
Boris Fausto, A Concise History of Brazil (Cambridge University Press, 1999)
In the consensus account, the Brazilian state preceded the Brazilian nation by more than a century. A functioning administrative state — courts, a currency, an army, a capital — existed continuously from the 1808 court transfer and the 1822 declaration of empire, run by a small Portuguese-descended elite that never fractured the territory the way Spanish American independence movements did. A shared sense of Brazilian nationhood, spanning a population that was demographically African, Indigenous, and European long before it was politically unified around that identity, developed far more slowly, gathering pace only through late-nineteenth-century nation-building projects — a national language policy, a public school system, and later the twentieth-century cultural nationalism of the Vargas era (1930–1945) — that tried retroactively to narrate a diverse, unequal population into a single people. This state-first, nation-after sequence differs sharply from cases where a nation’s sense of itself pushed for a state to contain it; in Brazil, the institutions came first and the story of belonging was built, deliberately and unevenly, to fit around them.
Thomas E. Skidmore & James N. Green, Brazil: Five Centuries of Change (Oxford University Press, 3rd ed., 2021)
For consensus historians the single force that best explains Brazil’s long arc is elite-managed continuity: a landholding and commercial elite that has repeatedly absorbed shocks — independence, abolition, the fall of the empire in 1889, the 1930 and 1964 coups, the 1985 return to democracy — without ever losing its grip on land, credit, and political access. Each transition in Brazilian history has been negotiated from above rather than imposed by popular revolution; even abolition, driven partly by the mounting cost of maintaining slavery and by international pressure, was managed by the same imperial elite that had profited from it, and the 1985 transition from military rule was itself brokered by generals and civilian politicians rather than won by an uprising. The result, in this reading, is a country whose formal institutions have changed dramatically — empire to republic, dictatorship to democracy — while its underlying distribution of land and wealth has proven remarkably resistant to those same transitions, a continuity that historians increasingly treat as the central puzzle of Brazilian development rather than a side effect of it.
Thomas E. Skidmore & James N. Green, Brazil: Five Centuries of Change (Oxford University Press, 3rd ed., 2021)
Alternative interpretations developed by respected historians that challenge or expand the mainstream view. These perspectives highlight debates within historical scholarship rather than presenting a single accepted explanation.
A revisionist reading, given weight in the essays collected in The Boundaries of Freedom, starts from the same map and the same population but refuses the consensus habit of narrating Brazil’s formation primarily through the decisions of monarchs, planters, and generals. It reframes the country’s founding population — enslaved and free Africans, Indigenous peoples, and the poor free population historians once treated as bystanders — as active shapers of the territory’s institutions rather than passive subjects of them. Rio de Janeiro’s docks, Bahia’s cane fields, and the mining towns of Minas Gerais were built and run day to day by enslaved labor whose choices — where to run, whom to petition, when to resist — repeatedly forced colonial and imperial administrators to adapt law and practice. This is not a claim that enslaved Brazilians controlled the country’s direction; it is a claim that the standard story, which credits elite decision-makers with managing an otherwise passive population through crisis after crisis, systematically understates how much of that management was itself a reaction to pressure applied from below, long before anyone in power called it politics.
Brodwyn Fischer & Keila Grinberg (eds.), The Boundaries of Freedom: Slavery, Abolition, and the Making of Modern Brazil (Cambridge University Press, 2022)
Where consensus historians treat abolition in 1888 as a single legislative threshold, revisionist scholarship treats it as the visible endpoint of a decades-long, largely unrecorded process of self-emancipation. The 1871 Free Womb Law, which freed children born to enslaved mothers, is read less as elite reform than as a legal opening that enslaved families and their advocates immediately exploited through the courts to press further claims to freedom. The mass flights from coffee plantations in São Paulo province during the 1880s — tens of thousands of enslaved workers simply walking off the land, often with the tacit cooperation of urban abolitionist networks — are treated as the decisive threshold, not the 1888 law that formally ratified an emancipation already underway in practice. This reordering matters because it relocates the engine of change from the imperial court in Rio de Janeiro to the plantations and the enslaved people living on them, challenging the consensus emphasis on 1808 and 1888 as elite-authored turning points by insisting that the most consequential decisions were made by people the official record barely names.
Brodwyn Fischer & Keila Grinberg (eds.), The Boundaries of Freedom: Slavery, Abolition, and the Making of Modern Brazil (Cambridge University Press, 2022)
The revisionist account complicates the idea that Brazil’s state simply preceded its nation. It argues that the population made continually excluded from formal citizenship — first as enslaved people, then as the largely landless, undocumented rural poor after 1888 — repeatedly used the tools available to them, court petitions, flight, informal land occupation, to force a redefinition of who the state actually served, well before any national project extended them equal standing. In this reading, the “nation” invoked by late-nineteenth-century elites was less a natural outgrowth of an existing state than a defensive narrative constructed partly in response to the demands and disruptions of people the state had excluded. The postponement of land reform after abolition, which left millions of freed Brazilians without property or political voice, is treated not as an oversight but as the deliberate terms on which formal nationhood was extended: inclusion in name, without the material basis to make that inclusion effective, a pattern revisionist historians trace forward into twentieth-century struggles over land and voting rights.
Brodwyn Fischer & Keila Grinberg (eds.), The Boundaries of Freedom: Slavery, Abolition, and the Making of Modern Brazil (Cambridge University Press, 2022)
Where the consensus names elite-managed continuity as Brazil’s defining process, the revisionist counter-thesis names contested, incomplete inclusion: a repeating cycle in which formally excluded populations — enslaved people before 1888, landless rural workers after it, favela residents in the twentieth and twenty-first centuries — force their way into partial recognition, only to find that recognition arrives without the land, credit, or security that would make it substantive. The mainstream account is not wrong that Brazilian elites have repeatedly renegotiated their position rather than lost it outright; the dispute is over which side of that renegotiation deserves the historical credit. Revisionist historians argue that treating elite adaptability as the central story obscures how much of that adaptability was a response to sustained pressure from below, and that a history organized around what elites conceded, rather than around who forced the concession, systematically underweights the agency of the enslaved, the poor, and — in the more recent chapters revisionist scholars are only beginning to write — the residents of Brazil’s informal urban peripheries.

Explains history through religion, culture, identity, political traditions, ideology and the stories societies tell about themselves. This lens asks how beliefs and shared identities have shaped historical development.
Seen through the lens of collective identity and culture, Brazil’s foundational story is the claim, first fully articulated by the sociologist Gilberto Freyre in the 1930s, that the country’s mixing of Portuguese, African, and Indigenous peoples produced a uniquely fluid, “racially democratic” society, free of the rigid segregation found in the United States or South Africa. Freyre’s account emphasized the intimate, if deeply unequal, contact of the colonial plantation household — the casa-grande, or big house, and the senzala, the enslaved people’s quarters, from which his most famous book takes its title — as the crucible of a new, mixed Brazilian people and culture, expressed in language, food, religion, and popular music. This is a genuinely contested thesis rather than settled history: later Brazilian scholars have shown that “racial democracy” described an aspiration or a self-image more than a lived reality, since Afro-Brazilians have continued to face measurable disadvantage in income, education, and representation. It remains foundational nonetheless, because Brazil’s national self-description — a country that sees itself as defined by mixture rather than division — still traces directly back to Freyre’s framing, even where his conclusions are rejected.
Gilberto Freyre, The Masters and the Slaves (University of California Press, 2nd rev. ed., 1986; orig. 1933)
This lens marks different thresholds than the political-institutional account. Portuguese colonization brought Catholicism as an official, unifying religious identity, but one that from the outset absorbed West African spiritual practice and Indigenous ritual into syncretic traditions — Candomblé, Umbanda — that persisted alongside, and often invisibly within, an outwardly Catholic culture. The 1888 abolition of slavery mattered here not primarily as a legal threshold but as a cultural one: newly freed Afro-Brazilians carried religious, musical, and culinary traditions from plantation regions into the growing cities, reshaping national culture from Rio de Janeiro’s carnival to the emergence of samba in the early twentieth century. The Vargas-era cultural nationalism of the 1930s and 1940s then took what had been marginalized Afro-Brazilian cultural practice and, selectively, promoted it as a symbol of the nation itself — samba and carnival became official emblems of Brazilian identity within a generation of the state actively suppressing the same traditions as disorderly. That reversal, from suppression to state-sponsored emblem, is treated in this lens as the decisive cultural turning point of the twentieth century.
Gilberto Freyre, The Masters and the Slaves (University of California Press, 2nd rev. ed., 1986; orig. 1933)
Through this lens, the Brazilian nation was not built by institutions alone but narrated into being through culture — music, festival, food, and religious practice — often ahead of, and sometimes in tension with, what the state itself was doing. The state in the 1930s promoted samba and carnival as unifying national symbols partly to paper over the deep regional, racial, and class divisions that political and economic history document plainly; the resulting national self-image, of a joyful, racially harmonious Brazil, functioned as much as an ideal to live up to as an accurate description of a country still marked by steep inequality. Religious syncretism tells a similar story: Candomblé and Umbanda, born from the forced coexistence of African, Indigenous, and Catholic practice under slavery, became broadly practiced and culturally prestigious well before Brazilian law extended full religious freedom or racial equality in fact. In this reading, cultural belonging in Brazil often ran ahead of political and economic inclusion — a nation performed and felt before it was fully, formally, made equal.
Gilberto Freyre, The Masters and the Slaves (University of California Press, 2nd rev. ed., 1986; orig. 1933)
The process this lens foregrounds is the long, uneven translation of a hierarchical, multiracial colonial society into a national culture that celebrates the mixture it once enforced through slavery. Each generation has renegotiated what “Brazilianness” means — from Freyre’s mid-twentieth-century racial democracy thesis, through the more explicitly critical Black consciousness and Afro-Brazilian rights movements that gathered strength from the 1970s onward and directly challenged Freyre’s framing, to contemporary debates over affirmative action and racial quotas in universities and public employment, introduced from the 2000s. What stays constant, in this account, is that Brazilian identity is fought over in cultural terms — who gets credit for the nation’s music, cuisine, and religion, and whether “mixture” is celebrated as harmony or named as a history of forced proximity and unequal power — as much as it is fought over in the courts or at the ballot box, making culture itself, not only law or economics, one of the primary arenas in which Brazil’s national story continues to be written and rewritten.

Explains history through geography, natural resources, trade, demographics, technology and economic structures. This lens explores how the physical environment and material conditions have influenced historical change.
Viewed through geography and economics, Brazil’s shape is a story of successive export commodities pulling settlement and infrastructure into different regions of an otherwise vast, thinly connected territory. The economic historian Celso Furtado’s classic account treats colonial and imperial Brazil not as a single integrated economy but as a series of largely separate export enclaves — sugar in the Northeast, gold and diamonds in Minas Gerais, later coffee in the Southeast — each organized to extract a single commodity for European and, later, North American markets, with limited investment in the connections between them. This left Brazil, at independence in 1822, as a vast territory with a genuinely national government but only a loosely stitched-together economy, its regions oriented outward toward Lisbon and later international buyers rather than toward each other. That pattern — a country whose regions are individually well connected to the world economy but historically under-connected to one another — still shapes Brazilian infrastructure and regional inequality today, and is, in this lens, the single most important fact about how the country’s geography and economy took shape.
Celso Furtado, The Economic Growth of Brazil: A Survey from Colonial to Modern Times (University of California Press, 1963)
This lens marks its thresholds by commodity cycle rather than by political event. The sugar cycle (roughly 1530–1700) concentrated wealth and enslaved labor in the humid coastal Northeast; its collapse, as Caribbean sugar undercut Brazilian prices, left the region economically stranded for more than a century. The gold and diamond rush in Minas Gerais (from the 1690s) briefly shifted Brazil’s economic center inland and financed the crown’s administration, before its own decline by the later eighteenth century. The coffee cycle, beginning in the Rio de Janeiro highlands in the 1820s and expanding into São Paulo, made Brazil the source of roughly 80 percent of world coffee supply by the 1920s and financed the railways, ports, and immigration — including the influx of Italian, Japanese, and other European labor after abolition — that built the modern industrial core around São Paulo. Each cycle’s rise and eventual exhaustion or replacement, this lens argues, mattered more for where roads, railways, and cities were built than any single law or election, wiring regional inequality directly into Brazil’s physical infrastructure.
Celso Furtado, The Economic Growth of Brazil: A Survey from Colonial to Modern Times (University of California Press, 1963)
Economic and geographic historians read Brazilian nation-building as substantially a story of infrastructure following commodities rather than an idea of nationhood organizing the territory from the start. São Paulo’s rise to Brazil’s dominant industrial and financial center traces directly to coffee-export wealth reinvested locally from the late nineteenth century onward, a regional head start that national political institutions, headquartered in Rio de Janeiro and later Brasília, never fully corrected. The Northeast, by contrast, was left economically marginal for generations after the sugar economy declined, a gap that decades of federal drought-relief and development programs in the twentieth century worked to narrow without eliminating. In this reading, the “nation” that Brazilian institutions eventually claimed to represent was, for much of the country’s history, an uneven patchwork of regional economies at very different levels of development, held together more by a shared central government and currency than by comparable prosperity — a structural imbalance this lens treats as more foundational to modern Brazil than any single constitutional or political settlement.
Celso Furtado, The Economic Growth of Brazil: A Survey from Colonial to Modern Times (University of California Press, 1963)
For this lens, the defining force in Brazilian history is commodity dependency and its regional legacy: a repeating pattern in which a single export — brazilwood, sugar, gold, coffee, and in the twentieth century soybeans, iron ore, and oil — has driven whichever region produces it to temporary prosperity, while leaving the national economy exposed to global price swings it cannot control. Furtado’s foundational analysis argued that this pattern, not any deficiency of national character or institutions, explains why Brazil industrialized later and more unevenly than economies less dependent on primary-commodity exports. Twenty-first-century Brazil has diversified considerably, becoming a major manufacturer and food exporter with a large domestic market of its own, but this lens still traces contemporary regional inequality — the wealth gap between the industrial Southeast and the historically export-dependent North and Northeast — directly back to which commodity each region happened to produce, and when, centuries ago, making geography and market timing, as much as policy, the forces that built the map of Brazilian inequality still visible today.
Celso Furtado, The Economic Growth of Brazil: A Survey from Colonial to Modern Times (University of California Press, 1963)
This is not a fifth lens — it names where the four accounts above genuinely disagree, and where they agree despite disagreeing about causes.
The four lenses agree that Brazil’s transitions — from colony to empire, from slavery to formal freedom, from dictatorship to democracy — were negotiated rather than revolutionary, and that each transition left deep inequalities of land, race, and region substantially intact. Where they part is over who deserves credit for change and what counts as that inequality being resolved.
The sharpest dispute is over the abolition of slavery in 1888. The scholarly consensus, following Fausto and Skidmore, treats abolition as an elite-managed reform, driven by economic pressure and international opinion, that the imperial government ultimately conceded. The revisionist scholarship gathered in The Boundaries of Freedom insists the true engine was the enslaved population itself — mass flight, legal petitioning under the 1871 Free Womb Law, and organized resistance — with the 1888 law formally recognizing an emancipation already underway rather than initiating one. Both accounts describe the same year and the same law; they disagree fundamentally about who was acting and who was merely reacting.
A second, quieter divergence concerns Brazil’s national self-image. The cultural lens treats Gilberto Freyre’s “racial democracy” thesis as genuinely foundational to how Brazilians have understood their own country for nearly a century, even while flagging it as contested. The economic and consensus lenses, tracking measurable outcomes in land, income, and infrastructure, describe a country whose regional and racial inequalities were never seriously interrupted by the mixture Freyre celebrated — the same history read as harmonious in one lens and as unresolved in another.
What all four agree on, finally, is the shape of the outcome: a country whose formal institutions have repeatedly changed while its underlying distribution of land, wealth, and opportunity has proven remarkably durable. They disagree about whether that durability reflects elite management, popular agency delayed rather than defeated, a cultural mythology outrunning material reality, or the long shadow of which commodity a region happened to produce first.

As of August 2026, Brazil’s formal political institutions remain stable: the country has held regular, competitive elections since 1985, and President Luiz Inácio Lula da Silva formally launched his bid for re-election in the October 2026 elections on 2 August 2026, within the ordinary constitutional calendar. What UCDP tracks as ongoing conflict in Brazil is not a contest for state power but organized, non-state violence: criminal factions including Comando Vermelho and the Primeiro Comando da Capital continue to fight each other and, in UCDP’s one-sided-violence category, to kill civilians, concentrated in the North and Northeast and in the urban peripheries of Rio de Janeiro and São Paulo, with UCDP’s Candidate Events Dataset recording several hundred battle-related deaths since the start of 2025. Brazilian federal and state governments have responded with periodic security operations in contested favela territories, but no comprehensive resolution to the underlying territorial contest between criminal factions has been reached.
In this narrower sense — not the survival of the state, but the state’s uncontested control of the territory and population within it — Brazil’s story remains open, even as its democratic institutions are not currently in question.

Brazil became independent from Portugal in 1822 and later became a republic, but its politics were often unstable, including a harsh military dictatorship from 1964 to 1985. Democracy returned in 1985, with a new constitution in 1988. According to UCDP, long-standing social and economic inequality, corruption, and underinvestment—especially in poor neighborhoods and prisons—created conditions in which powerful criminal groups could grow.
UCDP describes major non-state armed rivalries between organized crime groups, especially Comando Vermelho (CV), which emerged in a Rio de Janeiro prison in 1979, and the Primeiro Comando da Capital (PCC), formed in São Paulo’s prison system in 1993. Their influence spread nationwide and into drug trafficking. A truce broke down in 2016, after which prison riots and street violence increased as both sides fought for territory and international trafficking routes.
Brazil has not fought a state-to-state war since 1946 and often contributes to UN peacekeeping, including Haiti, but it still faces serious internal violence linked to organized crime. UCDP notes that government crackdowns can reinforce cycles of violence, and security forces and alleged “death squads” have been accused of one-sided violence, with disputed circumstances. Control over cross-border drug routes also connects Brazil’s insecurity to regional crime.

Brazil pursues a multi-alignment strategy, maintaining strong economic ties with China—its largest trading partner—while preserving security cooperation with the United States. This approach avoids entanglement in US-China rivalry, emphasizing diversified partnerships with Europe, India, and the Global South to safeguard autonomy amid geopolitical fragmentation. Under President Lula, Brazil leverages its position as a stable democracy and Latin America’s largest economy to balance these relationships, resisting binary alignments. Recent G20 initiatives under Brazil’s 2024 presidency highlighted this by promoting global governance reform and South-South cooperation without favoring one superpower.

Brazil maintains neutrality in the Russia-Ukraine conflict, advocating non-intervention, respect for sovereignty, and diplomatic solutions. It has abstained from Western sanctions against Russia, prioritizing trade relations while engaging both Kyiv and Moscow. Lula’s 2023 suggestion that Ukraine recognize Russian sovereignty over Crimea drew criticism but aligned with Brazil’s active non-alignment, oscillating between ties to Russia/China and Western partners. This posture reflects Brazil’s multipolar worldview, avoiding alliances that could disrupt commerce or global stability, as seen in its UN voting and G20 peace proposals.
Sources: CEBRI, Americas Quarterly
Brazil views BRICS as a platform for multipolar reform of global institutions like the UN Security Council and IMF, amplifying Global South voices. As 2025 BRICS chair, it applies active non-alignment to counterbalance Western dominance, fostering South-South cooperation despite concerns over China’s growing influence and 2023 expansions including Iran. Brazil opposed rapid BRICS growth to preserve its neutral stance but uses the group, alongside G20 and IBSA, for coalition-building on development, climate, and trade. This positions Brazil as a diplomatic hub bridging North-South and East-West divides.

After more than three centuries under Portuguese rule, Brazil gained independence in 1822 and maintained a monarchical system of government. This period ended after the abolition of slavery in 1888.
In 1889, the military proclaimed a republic. For years afterward, Brazilian coffee exporters politically dominated the country.
Populist leader Getúlio VARGAS rose to power in 1930 and governed through various democratic and authoritarian arrangements from 1930 to 1945. Democratic rule returned in 1945, including a democratically elected VARGAS administration from 1951 to 1954, and lasted until 1964.
In 1964, the military overthrew President João GOULART. The regime censored journalists and repressed and tortured dissidents in the late 1960s and early 1970s, and the dictatorship lasted until 1985, when it peacefully ceded power to civilian rulers; Congress passed the current constitution in 1988.
As the largest and most populous country in South America, Brazil continued to pursue industrial and agricultural growth and the development of its interior. After successfully weathering global financial difficulty in the late 20th century, Brazil was seen as a strong emerging market and a contributor to global growth under President Luiz Inácio LULA da Silva (2003–2010).
The awarding of the 2014 FIFA World Cup and 2016 Summer Olympic Games to Brazil was symbolic of this rise. However, from about 2013 to 2016, Brazil faced a sagging economy, high unemployment, and high inflation, emerging from recession in 2017.
In 2016, Congress removed President Dilma ROUSSEFF (2011–2016) for committing impeachable acts against Brazil’s budgetary laws, and Vice President Michel TEMER served the remainder of her second term. Operation Lava Jato uncovered a vast corruption scheme, and prosecutors charged several high-profile politicians with crimes; former President LULA was convicted of accepting bribes and served jail time (2018–19), though his conviction was overturned in 2021.
LULA returned to power in 2022 after narrowly defeating incumbent Jair BOLSONARO (2019–2022). Positioning Brazil as an independent global leader on climate change and promoting sustainable development, LULA took on the 2024 G20 presidency while balancing efforts against deforestation with sustainable energy and other projects aimed at alleviating poverty and promoting economic growth, including expanding fossil fuel exploration.
The armed conflict in Brazil is largely fueled by intense competition between organized crime groups, such as Comando Vermelho and Primeiro Comando da Capital (PCC), over territory and lucrative drug trafficking routes. These rivalries regularly erupt into violent clashes in urban areas and prisons. The fragmentation of criminal networks and limited state control in some regions create a climate where violence is used to enforce territorial boundaries and respond to perceived threats from other gangs or law enforcement.
Civilians in Brazil are frequently caught in the crossfire of gang turf wars and operations by security forces. According to UCDP data, most civilian deaths result from deliberate targeting by non-state groups, but significant harm is also attributed to security force actions. Residents of affected areas face threats to personal safety, elevated homicide rates, and possible displacement, with daily life often disrupted by fear of sudden violence or mistaken identity during operations or reprisals.

The Government of Brazil is responsible for law enforcement and public security operations against criminal organizations. According to UCDP, deliberate killings of civilians by government forces have been documented, reflecting significant risks for people living in affected areas.
Comando Vermelho is a major Brazilian criminal organization involved in violent confrontations with rival gangs and other criminal groups. They have a documented record of deliberate civilian killings, making them one of the principal drivers of violence and risk to non-combatants in affected regions.
The PCC is another influential criminal organization with a strong presence in several Brazilian states. Its ongoing violent rivalries with Comando Vermelho and others put many civilians at risk, as evidenced by high numbers of deliberate and collateral violence, including targeted killings.
Bonde do Maluco operates mainly in Brazil's northeast, clashing with rival gangs and contributing to violence against civilians through both turf conflicts and deliberate attacks, according to UCDP incident records.
Bonde dos 40 is implicated in frequent and violent confrontations with larger national gangs. Reports indicate the group also deliberately targets civilians in its operations.
Cartel do Norte is one of several regional gangs clashing with larger groups over territory. Compared to the main organizations, the group appears to be involved in fewer incidents resulting in civilian casualties, according to available data.
Sindicato do Crime is one of several state-level groups involved in turf conflicts with national gangs. Civilian impact appears lower relative to dominant groups, based on current event reporting and UCDP classifications.
Numerous smaller and regionally focused gangs contribute to local violence and gang rivalries. Their civilian impact is lower compared to the main syndicates, but they play a role in the fragmented nature of urban violence in Brazil.
Brazil's armed violence is driven primarily by territorial struggles between powerful criminal organizations, rival gangs, and security forces, centered on control of illicit markets and urban areas. The resulting conflict landscape is highly fragmented, placing civilians at risk from both deliberate and indiscriminate violence.
Brazil adopts a democratic constitution after Getúlio Vargas’s Estado Novo dictatorship, strengthening presidential powers, federalism, and the armed forces’ political role. This institutional legacy later shapes military intervention, urbanization, and uneven development that help underpin contemporary security and criminal-violence challenges.
Armed forces overthrow left-leaning President João Goulart, launching a US-backed military regime. The dictatorship centralizes power, represses opposition, and expands security forces, while deepening social inequalities and abuses that weaken trust in state institutions, later influencing how communities relate to today’s police and criminal organizations.
The regime issues AI-5, suspending habeas corpus, shutting Congress, and widening powers of security forces against dissent. This normalizes militarized public order and impunity for abuses, a pattern that informs later heavy-handed policing and lethal state violence seen in contemporary operations against suspected criminals and civilians.
The end of Brazil’s “economic miracle” brings inflation and slowing growth. Rapid, poorly planned urbanization expands favelas in major cities without adequate services or policing, creating spaces where informal armed groups and early drug networks grow, laying groundwork for later dominance by criminal organizations like Comando Vermelho.
A political amnesty allows exiled opponents and some regime agents to escape accountability. Brazil transitions toward civilian rule without fully reforming security institutions, preserving structures and attitudes in policing and prisons that later facilitate the rise of violent criminal factions and persistent one-sided violence against civilians.
Mass nationwide protests demand direct presidential elections, forcing the military to accept political liberalization and civilian leadership. While democratization advances, public security remains largely militarized and unreformed, leaving a gap between democratic promises and everyday policing that encourages communities to seek protection from, or join, criminal groups.
The “Citizen Constitution” restores civil liberties and strengthens states and municipalities, but maintains military-style policing and overcrowded prisons. Fragmented authority over public security and justice contributes to coordination gaps, enabling organized crime to expand influence in urban peripheries and detention facilities, patterns central to today’s violence dynamics.
As Andean cocaine production surges, Brazil’s borders and ports become major transit routes. Weak frontier control, corruption, and unequal development encourage drug-trafficking networks, especially in the North and Northeast, setting conditions for later territorial disputes and violent competition between emerging organizations like Comando Vermelho and PCC.
Military police kill over 100 inmates during a riot at São Paulo’s Carandiru prison. The episode signals extreme prison overcrowding, brutality, and limited accountability, helping fuel narratives of state hostility that later motivate inmate organization and the formation of powerful criminal groups such as Primeiro Comando da Capital.
Comando Vermelho, formed earlier in Rio’s prisons, consolidates control over favela drug markets and territorial “ownership.” Its model of prison-based coordination and community penetration influences other factions nationally, deepening cycles of armed confrontations with police and rival groups that echo in present-day urban and prison violence.
PCC, founded in São Paulo’s prisons after the 1992 massacre, grows into Brazil’s most powerful criminal organization. It organizes inmates, standardizes rules, and expands drug trafficking. Its prison-centered structure and regional expansion prefigure today’s factional struggles, especially after later splits and disputes over trafficking routes.
PCC orchestrates coordinated attacks on police, buses, and public buildings, plus riots in dozens of prisons. Hundreds die, many in controversial police operations. The violence exposes the state’s fragile control over prisons and public security, accelerating militarized responses and embedding PCC as a central actor in Brazil’s conflict landscape.
A breakdown in PCC–Comando Vermelho cooperation ignites violent disputes over Amazonian trafficking corridors, border crossings, and prison control. Killings surge in the North and Northeast, and inside detention centers, creating today’s non-state conflict dynamics and reinforcing Brazil’s status as a hub of organized armed criminal violence.
Federal and state authorities expand military-style interventions, including Rio de Janeiro’s federal intervention and later hardline policies under President Bolsonaro. Police killings and controversial operations grow, especially in marginalized areas, entrenching patterns of one-sided violence against civilians that continue alongside criminal-group warfare in 2024.
