Cartographers translated imperial ambition into visual claims; maps functioned as political documents as much as geographic tools.
Early European Explorations & Imperial Divisions
Treaty of Tordesillas \,(1494)
Papal-brokered line \,(\approx\ 46^\circ\,W) divided new lands: Spain got west of the line, Portugal east.
Set precedent for diplomatic partitioning of non-European worlds.
Quest for a Northwest Passage
England, France, Netherlands launched repeated expeditions through North America seeking a route to Asia.
Failure of passage intensified focus on colonisation & resource extraction in the Americas themselves.
Cartographic Power & Propaganda
Printed maps circulated claims far faster than physical occupation could; they legitimised spheres of influence in European eyes.
Formation of Atlantic Empires (ca. 1550\text{–}1660)
Spain
Controlled vast territories: Mexico, most of South America, Caribbean, portions of North America.
Extracted bullion (silver, gold) that would later fuel European inflation.
Portugal
Dominated Brazil; established fortified trading posts (feitorias) along African coast and in Indian Ocean.
Britain
Settled North American eastern seaboard (e.g., Virginia, New England) and Caribbean sugar islands (Barbados, Jamaica).
France
Early presence in Canada (St. Lawrence, Quebec); later expansion down Mississippi to Louisiana.
Netherlands
Created far-flung trading empire (Dutch West India Company); settlements in New Netherland (present-day New York) and Caribbean islands (Curaçao, Aruba, St. Eustatius).
The Columbian Exchange: Trans-Oceanic Biological & Demographic Flows
People
Europeans, enslaved Africans, and forcibly displaced Indigenous groups circulated around the oceanic rim.
Plants & Animals
New World ➜ Old World: maize, potatoes, tomatoes, cacao.
Old World ➜ New World: wheat, sugarcane, horses, cattle, pigs.
Diseases
Smallpox, measles, influenza devastated Indigenous populations (up to 90\% mortality in some regions).
Syphilis (debatably) travelled from Americas to Europe.
African Societies & the Transatlantic Slave Trade
Geographic Sources
West & Central Africa (Senegambia, Gold Coast, Bight of Benin, Kongo, Angola) supplied the majority of enslaved peoples.
Coastal Kingdoms as Intermediaries
Coastal polities (e.g., Dahomey, Asante, Kongo) exchanged captives for firearms, textiles, metal goods.
Internal warfare often intensified to meet European demand.
Political Consequences
Some states gained temporary power; others collapsed under depopulation.
Demographic & Cultural Impact
Forced migration of approximately 12\,\text{million} Africans by 1800 reshaped populations across the Atlantic.
Enslaved peoples carried agricultural knowledge, religious practices (West-Central African spirit veneration ➜ Afro-Christian syncretisms), music, and language patterns.
Economic Impact: Commerce & the Price Revolution
Influx of Bullion
Silver from Potosí and Zacatecas, gold from Mexico & Colombia flooded Europe.
Spanish galleons moved \approx 150\text{–}200\,\text{tons} silver/year by late 1500\text{s}.
The Price Revolution (ca. 1500\text{–}1650)
Graphically documented inflation: general prices rose 300\%–400\%.
Causes: bullion influx, population rebound after Black Death, increased monetisation.
Mercantilism Emerges
States pursued positive trade balances, hoarded precious metals, used colonies as captive markets.
Navigation Acts, exclusive charters to joint-stock companies (e.g., Dutch VOC, English EIC) institutionalised state-backed commerce.
Social & Cultural Transformations
Demographic Snapshot by 1700
European migrants: 1.5\,\text{million}.
African enslaved: 12\,\text{million} (trafficked, though only \approx\,10\,\text{million} survived Middle Passage).
Indigenous mortality: up to 90\% through disease, warfare, displacement.
Indigenous alliances manipulated by Europeans (e.g., Iroquois–Huron conflicts linked to French & Dutch fur trades).
Legacies of the Atlantic World (to 1660 & Beyond)
Prototype for Globalisation
Regular, sustained, multi-directional exchange of people, goods, ideas foreshadowed later worldwide networks.
Cultural Exchange & Hybridities
Languages (pidgins, creoles), religious syncretism, blended artistic forms endure today.
Economic Foundations
Plantation complex (sugar, tobacco) model later replicated in cotton, coffee, rubber industries.
Mercantile capitalism paved way for industrial-era expansion.
Enduring Inequalities
Racialised hierarchies, underdevelopment of extractive colonies, and diaspora communities remain rooted in this era’s structures.
Connections to Earlier & Later Contexts
Builds on Age of Discovery (Dias 1488, Columbus 1492) and precedes Age of Enlightenment & Industrial Revolution.
Silver flow tied Americas to Ming/Qing China via Manila Galleons—the first truly global commodity chain.
Philosophical debates on human rights (Bartolomé de Las Casas vs. Juan Ginés de Sepúlveda) foreshadow modern discourse on universalism, racism, and empire.
Ethical & Philosophical Dimensions
Forced migration and genocide raise questions of moral responsibility, reparations, and historical memory.
Religious justifications for conquest (Requerimiento, Papal Bulls) challenged by emerging critics, laying groundwork for secular concepts of natural rights.
