By the late 1400s, European nations began exploring the Americas. But why?
Gold: European nations wanted wealth from gold, silver, and new trade routes.
Glory: Exploration brought fame to countries and explorers.
God: Many Europeans wanted to spread Christianity (especially Catholics from Spain & Portugal).
The Renaissance (1300s–1500s) encouraged curiosity, innovation, and learning.
Inventions like the printing press (spread new ideas) and the compass & astrolabe (made navigation easier) helped exploration.
Mercantilism: European nations believed wealth = power, so they wanted more colonies to bring in gold & raw materials.
New Trade Routes: After the Ottoman Empire took over Constantinople (1453), European countries wanted new routes to Asia for spices and luxury goods.
By the 1400s, European nations wanted wealth, power, and religious expansion, which pushed them to explore new lands.
As European nations began exploring, several key explorers played a major role in discovering and claiming new lands.
Prince Henry the Navigator: Funded exploration schools and voyages along Africa’s coast.
Bartolomeu Dias (1488): First European to reach the southern tip of Africa (Cape of Good Hope).
Vasco da Gama (1498): First European to reach India by sea, creating a direct trade route.
Christopher Columbus (1492):
Sponsored by Spain’s Ferdinand and Isabella to find a new route to Asia.
Landed in the Caribbean (Bahamas) but thought he was in India.
His voyage opened the Americas to European colonization.
Ferdinand Magellan (1519-1522):
Led the first voyage to circumnavigate the globe (though he died before finishing).
Hernán Cortés (1519):
Conquered the Aztec Empire (Mexico) with the help of superior weapons and alliances.
Francisco Pizarro (1532):
Conquered the Inca Empire (Peru) by capturing the emperor Atahualpa.
John Cabot (England, 1497): Claimed Newfoundland for England.
Jacques Cartier (France, 1534): Explored the St. Lawrence River (Canada).
Henry Hudson (Dutch & English, early 1600s): Explored the Hudson River and Hudson Bay.
European explorers claimed new lands, set up trade routes, and began the colonization of the Americas, which would change history forever.
When Europeans arrived in the Americas, they didn’t just bring themselves—they also brought plants, animals, diseases, and ideas in what became known as the Columbian Exchange.
A massive exchange of goods, crops, animals, people, and diseases between the Old World (Europe, Africa, Asia) and the New World (the Americas).
Named after Christopher Columbus, whose voyages started the global connection.
From the Old World → New World | From the New World → Old World |
---|---|
Diseases: Smallpox, measles, flu (killed 90% of Native Americans) | Crops: Potatoes, maize (corn), tomatoes, cacao (chocolate), tobacco |
Livestock: Horses, cows, pigs, sheep | Animals: Turkeys |
Crops: Wheat, rice, sugarcane, coffee | Medicinal Plants: Quinine (used for malaria) |
Technology & Religion: Guns, Catholicism | Precious Metals: Gold, silver (from the Americas to Europe & Asia) |
For Europe:
New foods (potatoes, corn) → Population boom.
Gold & silver from the Americas → More wealth & power.
For the Americas:
Diseases wiped out millions of Indigenous people (90% mortality in some areas).
Introduction of horses changed Native American culture (especially in the Great Plains).
For Africa:
The demand for labor in the Americas → Transatlantic Slave Trade grew.
The Columbian Exchange dramatically changed the world by introducing new foods, animals, and cultures, but it also led to disease, forced labor, and colonization.
As European colonies grew in the Americas, they needed a large labor force to work on plantations. This led to the expansion of the Transatlantic Slave Trade, which forcibly brought millions of Africans to the Americas.
Decline of Indigenous Labor: Diseases from the Columbian Exchange killed up to 90% of Native Americans, making them less available as laborers.
Demand for Cash Crops: European plantations in the Americas needed laborers to grow sugar, tobacco, and cotton.
African Slave Trade Networks: Some African kingdoms (like the Kingdom of Dahomey and Ashanti Empire) already practiced slavery and sold captives to Europeans in exchange for guns and goods.
The Transatlantic Slave Trade was part of a larger system called the Triangular Trade, which connected Europe, Africa, and the Americas.
Europe → Africa: Manufactured goods (guns, textiles, rum) were sent to African leaders in exchange for enslaved people.
Africa → Americas (Middle Passage): Enslaved Africans were transported under horrific conditions (chained, crammed ships, disease, abuse).
Americas → Europe: Plantation crops (sugar, cotton, tobacco) were sent back to Europe for profit.
The Middle Passage was the brutal voyage from Africa to the Americas.
Conditions:
People were packed tightly in slave ships with little space to move.
Disease, starvation, and abuse killed 15-20% of enslaved people before arrival.
Survivors were sold into slavery and forced to work in plantations and homes.
Africa: Devastated populations, increased warfare, and loss of millions of young men and women.
The Americas: Built economies based on slave labor, leading to racial hierarchies and systemic racism.
Europe: Gained massive wealth from plantation economies.
The Transatlantic Slave Trade fueled European economies but caused immense suffering and lasting social impacts for Africans and their descendants.
As Spain and Portugal expanded their empires in the Americas, they established colonial systems that shaped the region’s culture, economy, and society.
Spain and Portugal argued over land claims in the New World.
The Pope created the Line of Demarcation, dividing the world:
Spain controlled most of the Americas.
Portugal controlled Brazil and parts of Africa & Asia.
Spanish colonizers were granted land and Indigenous labor by the Spanish Crown.
In exchange, they were supposed to "protect" and convert Indigenous people to Christianity.
Reality: It became a system of brutal forced labor (like slavery), especially in gold & silver mines.
Spain and Portugal spread Catholicism through missionaries.
Franciscans and Jesuits built missions (church settlements) to convert Indigenous people.
Effects: Some Indigenous people converted, but many resisted or blended Christianity with their own beliefs.
Spanish colonies developed a rigid social hierarchy based on race:
Rank | Group | Description |
---|---|---|
1 | Peninsulares | Spaniards born in Spain (held top government roles). |
2 | Criollos (Creoles) | Spaniards born in the Americas (wealthy but less political power). |
3 | Mestizos & Mulattoes | Mixed-race people (Spanish + Indigenous or Spanish + African). |
4 | Indigenous & Africans | Forced laborers with little rights. |
The Casta System reinforced Spanish dominance and limited social mobility for non-Europeans.
Spanish and Portuguese colonization shaped economies (gold, plantations), societies (rigid racial hierarchy), and cultures (Catholic influence), but also caused forced labor, Indigenous resistance, and long-term inequalities.
While Spain and Portugal dominated early colonization, France, the Netherlands, and England also established colonies in North America. Each had different goals and strategies.
Location: Canada (New France), Great Lakes, Mississippi River (Louisiana).
Economy:
Focused on fur trading, especially beaver pelts, which were valuable in Europe.
Partnered with Native American tribes like the Huron for trade.
Relations with Natives:
Friendly alliances with Indigenous groups.
French traders often lived among Native peoples and intermarried.
Catholic Missions: Jesuit missionaries tried to convert Natives but were less aggressive than Spain.
Location: New Netherland (present-day New York, Hudson River Valley).
Economy:
Focused on trade, especially fur and shipping.
The Dutch West India Company controlled New Amsterdam (New York City).
Relations with Natives:
Mainly business-focused; did not prioritize conversion.
Some conflicts, but mostly peaceful trade.
Location: East Coast of North America (Jamestown, Plymouth, Massachusetts Bay).
Economy:
Early colonies (Jamestown) relied on tobacco plantations for profit.
New England focused on small farming, trade, and fishing.
Relations with Natives:
At first, some cooperation (Squanto helped Pilgrims).
Eventually led to violent conflicts (e.g., Powhatan Wars, Pequot War, King Philip’s War).
Religion:
Puritans and Pilgrims sought religious freedom in New England.
Anglicans settled in the South.
Each European power had different colonization strategies:
French: Trade and alliances with Natives.
Dutch: Business-focused with minimal settlement.
English: Permanent settler colonies, often leading to Native conflicts.
As European powers expanded their territories in North America, conflicts arose between colonizers, Indigenous peoples, and rival European nations. These struggles shaped the political and social landscape of the New World.
Indigenous groups resisted European expansion through warfare, diplomacy, and alliances.
The Pueblo Revolt (1680):
The Pueblo people (New Mexico) revolted against Spanish rule.
Led by Popé, they expelled the Spanish for 12 years before Spain regained control.
Spain lessened forced labor and religious oppression afterward.
King Philip’s War (1675-1676):
Metacom (King Philip) led a Native alliance against English settlers in New England.
One of the bloodiest conflicts in U.S. history.
Colonists won, leading to the near-destruction of many Indigenous groups.
European nations often competed for land, trade routes, and influence.
Anglo-Dutch Wars (1650s-1670s): England seized New Netherland from the Dutch (renamed New York).
French and Indian Wars:
England and France fought for control over North America.
These conflicts would later escalate into the Seven Years’ War (1754-1763).
The growing European presence in the Americas transformed the world.
Columbian Exchange effects continued:
New foods (corn, potatoes) boosted European populations.
Disease (smallpox, measles) continued devastating Indigenous peoples.
African Slavery Expanded:
The demand for plantation labor increased reliance on enslaved Africans.
Colonization led to violent conflicts with Indigenous peoples, European rivalries, and lasting global impacts through the Atlantic trade system.
