Extensive European colonisation of Latin America began in 1492, when a Spanish expedition headed by the Genoese navigator Christopher Columbus sailed west in search of a new trade route to the Far East (India) but inadvertently reached the Americas.
- Columbus’s first two voyages (1492–93) reached the Bahamas and various Caribbean islands, including Puerto Rico and Cuba.
As the sponsor of Columbus’s voyages, Spain became the first European power to settle and colonise the largest areas — stretching from North America and the Caribbean to the southern tip of South America.
- Spanish cities were founded as early as 1496, with Santo Domingo (in present-day Dominican Republic) among the first.
France founded colonies in eastern North America, several Caribbean islands, and small coastal parts of South America.
Portugal colonised Brazil and also attempted, from 1499, to colonise parts of the Canadian coast.
Europe, preoccupied with internal wars and only slowly recovering from population losses caused by the bubonic plague, could not have foreseen in the early 1400s the rapid rate at which it would soon grow in wealth and power through overseas expansion.
Eventually, the entire Western Hemisphere came under the ostensible control of European governments, bringing profound changes to its landscape, population, and plant and animal life.
- In the 19th century alone, over 50 million people left Europe for the Americas.
The period following 1492 is known as the era of the Columbian Exchange — a dramatically widespread exchange of animals, plants, culture, human populations (including enslaved people), communicable diseases, and ideas between the American and Afro-Eurasian hemispheres following Columbus’s voyages.

Early European Explorations and Conquests

Early explorations and conquests were undertaken by the Spanish and Portuguese immediately following their own final reconquest of Iberia in 1492.
In the 1494 Treaty of Tordesillas, ratified by the Pope after Columbus’s return, Spain and Portugal divided the entire non-European world into two zones of exploration and colonisation, separated by a north–south boundary running through the Atlantic Ocean along the eastern part of Brazil.
- Based on this treaty, and on early claims made by the Spanish explorer Balboa (discoverer of the Pacific Ocean in 1513), Spain conquered large territories across North, Central, and South America.
By the mid-16th century, the Spanish Crown had gained control of much of western South America, Central America, and southern North America, in addition to its earlier Caribbean territories.
Over the same period, Portugal claimed lands in North America (Canada) and colonised much of eastern South America, naming the territory Santa Cruz and later Brazil.
Other European powers soon disputed the terms of the Treaty of Tordesillas.
- England and France attempted to plant colonies in the Americas in the 16th century, but these early attempts failed.
- England, France, and the Dutch Republic succeeded in establishing permanent colonies the following century.
  - Some of these colonies were established on Caribbean islands already conquered by the Spanish or depopulated by disease, while others were established in eastern North America — territory Spain had not colonised north of Florida.
As more nations developed an interest in colonising the Americas, competition for territory grew increasingly fierce, and colonists frequently faced threats of attack from neighbouring colonies, indigenous tribes, and pirates.

Early State-Sponsored Colonists

The first phase of well-financed European activity in the Americas began with Christopher Columbus’s Atlantic crossings (1492–1504), sponsored by Spain, whose original objective was to find a new route to India and China — then known as “the Indies.”
Cabral reached Brazil and claimed it for Portugal.
Amerigo Vespucci, working for Portugal on voyages between 1497 and 1513, established that Columbus had in fact reached a new set of continents; a Latinised version of his first name — America — was subsequently used to name the two continents.
In 1513, Balboa crossed the Isthmus of Panama and led the first European expedition to sight the Pacific Ocean from the west coast of the New World, claiming the ocean and all adjoining lands for the Spanish Crown.
It was not until 1517 that another expedition, launched from Cuba, visited Central America in search of slaves.
These explorations were followed — notably in the case of Spain — by a phase of conquest:
- The Spaniards, having just completed the Reconquista of Spain from Muslim rule, were the first Europeans to colonise the Americas.
- Ten years after Columbus’s discovery, the administration of Hispaniola (in the Caribbean) was entrusted to Nicolás de Ovando, a Spanish soldier from a noble family.
- The encomienda system — a legal mechanism used by the Spanish Crown during colonisation to regulate Native Americans and reward individual Spaniards for services to the Crown — was progressively established, granting settlers tribute in the form of indigenous labour and taxation.
- Over the century and a half following Columbus’s voyages, the native population of the Americas plummeted by an estimated 80%, largely due to outbreaks of Old World diseases.
- In 1532, Charles V, Holy Roman Emperor of the Spanish Empire, dispatched a viceroy to Mexico to check Hernán Cortés’s independentist ambitions; Cortés belonged to the generation of Spanish colonisers who initiated the first phase of Spanish colonisation in the Americas.
- Two years later, Charles V signed the New Laws, which prohibited slavery and forced labour, while simultaneously claiming all American lands and their indigenous inhabitants as subjects of the Crown.
In May 1493, Pope Alexander VI issued a papal bull granting the newly discovered lands to the Kingdom of Spain, in exchange for the evangelisation of their inhabitants.
- Accordingly, many priests accompanied Columbus on his second voyage.
- In 1537, a papal bull promulgated by Pope Paul III recognised that Native Americans possessed souls, thereby prohibiting their enslavement — though some argued that a native who had rebelled and was later captured could still be enslaved.
The process of Christianisation was initially violent:
- When the first Franciscans arrived in Mexico in 1524, they burned sites of pagan worship, alienating much of the local population.
- By the 1530s, missionaries began adapting Christian practices to local customs, including building new churches on the sites of ancient places of worship.

Colonisation by Spain

Colonial expansion was initiated by the Spanish conquistadores and developed by the Monarchy of Spain through its administrators and missionaries.
The motivations behind this expansion were twofold: trade and the spread of the Catholic faith through indigenous conversion.
Beginning with Columbus’s arrival in 1492 and continuing for over three centuries, the Spanish Empire expanded across half of South America, most of Central America and the Caribbean islands, and much of North America.
In the early 19th century, the Spanish American wars of independence led to the emancipation of most Spanish colonies in the Americas, with the exception of Cuba and Puerto Rico.
- These were finally relinquished in 1898 following the Spanish–American War, along with Guam and the Philippines in the Pacific — marking the political end of Spanish colonisation in the Americas.

Demographic Impact

It is estimated that around 240,000 Spaniards emigrated to the Americas in the 16th century, rising to about 500,000 in the 17th century, predominantly to Mexico and Ecuador.
In Hispaniola, the indigenous population — once several hundred thousand — had declined to 60,000 by 1509.
The native Amerindian population of Mexico declined by an estimated 90% by the early 17th century.
In Peru, the indigenous Amerindian population of roughly 6.5 million fell to 1 million by the early 17th century.
The indigenous Californian population, estimated at 310,000 at first contact in 1769, had dropped to 25,000 by 1910 — though the vast majority of this decline occurred after the Spanish period, during the Mexican and American phases of Californian history (1821–1910).

Cultural Impact

The Spaniards were committed, by royal decree, to converting their New World subjects to Catholicism.
- However, initial efforts met with limited success, as indigenous people often incorporated Catholic elements into their long-standing traditional ceremonies and beliefs.
Many native expressions, art forms, and practices were viewed as idolatry and consequently prohibited or destroyed by Spanish missionaries, military personnel, and civilians.
While the Spanish did not impose their language as forcefully as their religion, some indigenous languages of the Americas were nonetheless gradually replaced by Spanish.

Colonisation of Brazil

The land now known as Brazil was claimed by Portugal in April 1500, upon the arrival of the second Portuguese India Armada, commanded by Cabral, on the Bahian shores.
The Portuguese encountered indigenous nations divided into several distinct tribes.
- Although the Portuguese sailors stayed for only nine days, the local population was quickly fascinated by the iron tools, the Catholic mass, and the alcoholic beverages they observed.
Because of this perceived interest in Roman Catholicism, the Portuguese assumed the indigenous people would readily convert to Christianity once educated in the faith.
Portugal, however, did not initially appreciate Brazil’s value, as its trade priorities remained centred on India and the Far East.
- It was primarily New Christian investors (converted Jews) who scouted and defended the coast, trading in brazilwood and sharing monopoly contracts with the Portuguese king.
- The king, in turn, permitted private investors to conquer designated areas for their own benefit — but at their own cost — resulting in a combination of royal and private ownership.
- Brazilwood yielded a rich red dye that was highly valuable for colouring textiles and clothing, making Brazil an increasingly attractive prize for rival powers.
It was not long before other European nations sought to conquer and occupy parts of Brazil.
- The French and Spanish made repeated attempts to enter Brazil, but the Portuguese fought determinedly against these invasions, dispatching strong fleets to clear the coast.
Portugal’s other key strategy was establishing permanent settlements — the first being São Vicente, founded in 1532.
- Although this first settlement was founded in 1532, effective colonisation began in 1534, when Dom João III divided the territory into fifteen hereditary captaincies.
- This arrangement proved problematic, and in 1549 the king appointed a Governor-General to administer the entire colony.
The Portuguese had already established a culture of violent domination and abuse in India, but this approach did not go down well with the Brazilian locals, who captured and ritually consumed their Portuguese “owners” in elaborate ceremonies — forcing the king to heed indigenous warnings and assume direct control.
Sousa became the first Governor-General of Brazil in 1549, serving until 1553.
- By royal order, Sousa declared Salvador the capital city.
- He waged war on the indigenous population to counter the threat posed by the French, who sought to cooperate with local tribes to increase their own influence.
- As Governor-General, Sousa played an integral role in building towns, sugar mills, and important public buildings.
- The Crown later instructed Sousa to treat the locals well, with the aim of converting them to Christianity; those who refused conversion could be enslaved.
As Portuguese and indigenous communities intermingled, so too did their cultures and genes — colonists adopted Brazilian customs even as indigenous people absorbed elements of European culture.
- As the Portuguese crown and church underwent renewal, slavery fell out of favour, and the number of enslaved people in Brazil declined sharply.
- The Portuguese assimilated some native tribes, while others gradually disappeared through prolonged conflict or European diseases to which they had no immunity.
In 1562 and 1563, outbreaks of smallpox, measles, and influenza devastated the local population, followed by a severe famine.
- Desperate for food and income, many locals sold themselves into slavery rather than starve.
Investors were increasingly required to fund land grants and sugar mills, and Portuguese colonisers had to maintain positive working relationships with local communities to sustain this economy.
- Sugar would later become the agricultural and financial pillar of Brazil’s colonial economy.
Towards the end of the 1500s, the “Indians” fled into Brazil’s interior to escape colonial pressures, prompting European settlers to import enslaved labour from Africa instead.
- By the mid-16th century, sugar had become Brazil’s most important export owing to rising international demand.
- By 1700, over 963,000 African slaves had been transported across the Atlantic to work in Brazil — more than were brought to all other parts of the Americas combined.
Through continued wars against the French, the Portuguese steadily expanded their territory: southeast to Rio de Janeiro in 1567, and northwest to São Luís in 1615.
- They also sent military expeditions into the Amazon rainforest, conquering English and Dutch strongholds, and in 1680 reached the far south, founding Sacramento (present-day Uruguay).
At the end of the 17th century, sugar exports began to decline, but the discovery of gold in the 1690s in the region later known as Minas Gerais (“General Mines”) rescued the colony from imminent collapse, drawing thousands of immigrants from across Brazil and Portugal.
In 1775, the three colonies of Portuguese America — the State of Brazil, the State of Maranhão and Piauí, and the State of Grão-Pará and Rio Negro — were unified into a single colony under the State of Brazil, an arrangement that lasted until the end of the colonial period.
- As a result, unlike its Spanish-speaking neighbours, Brazil did not fragment into several separate countries after independence.
Spain attempted to check Portuguese expansion into territory it claimed under the 1494 Treaty of Tordesillas, briefly conquering Uruguay in 1777.
- However, a new treaty signed the same year settled the territorial dispute: Spain ceded Brazilian territories (including the Amazon Basin) to Portugal in exchange for retaining control of Uruguay, confirming Portuguese sovereignty over the lands it had gained and largely establishing the modern borders of Brazil.

From Colony to United Kingdom

During Napoleon’s invasion of Portugal (1807), the Portuguese royal family fled to Brazil, establishing Rio de Janeiro as the de facto capital of Portugal.
- This move inadvertently created many of the institutions Brazil would need to function as an independent state, and crucially, freed it to trade with other nations at will.
After Napoleon’s defeat in 1815, King John VI of Portugal — seeking to retain the capital in Brazil and ease Brazilian fears of a return to colonial status — elevated Brazil’s status to an equal, integral part of the United Kingdom of Portugal, Brazil, and the Algarves, rather than a mere colony, a status it held for the next seven years.

Development of Spanish American Independence

The accompanying map (1750–1808 progression) illustrates the shifting political control across Latin America during the independence period, using the following colour scheme:
- Red — Government under traditional Spanish law
- Pale — Loyal to the Supreme Central Junta or Cortes
- Yellow — American junta or insurrection movement
- Green — Independent state declared or established
- Blue — Height of French control of the Peninsula
