4. Transoceanic Interconnections

1450-1750

4.1 Technological innovations

ship design, navigation, mapmaking
Portuguese caravel: lighter, faster, highly maneuverable
navigation
currents in Atlantic Ocean are fixed (unlike monsoons)
Europeans mapped the wind currents as well as water currents
gunpowder combined with ironwork = guns and cannons

Ships

Old

Arab dhow
designed for Indian Ocean sailing
not for long distances
Chinese junk
large, flat bottom
carried lots of tribute gifts and cargo

New

caravel
smaller than junk
could access rivers, coastal waters
2 sets of sails
square: speed
lateen: maneuverability
fluyt
16th-century Dutch cargo ship
could carry twice the cargo for half the price and crew
1670: half of all European sea trade
carrack
15th century
3-4 masts
traded along African coast, Asia, Americas
example: Columbus’s Santa Maria

Early innovations

astrolabe
innovation from House of Wisdom
allowed sailors to determine latitude
compass
Chinese (from Han Dynasty 206 BCE)
later adopted by Europeans in 13th
allowed sailors to determine their position by using Earth as a magnet
lateen sail
early evidence suggests it was used in the Mediterranean as early as 2nd
allowed sailors to catch winds from both sides of the ship
made it easier for boats to travel in different directions, travel in large bodies of water

European discovery of naval technology

learned about naval technology from preservation of Greek knowledge combined with knowledge from House of Wisdom and Asian technology
al-Andulus (southern-most part of Spain) was formerly under Islamic rule; was a European capital of social and cultural exchange

Wind patterns

astronomical chart
map of stars and galaxies that sailors used to guide ships
increased trade and expansion as a result
1600s: scholars began using telescopes to create charts
resulted in increased accuracy for maritime travel
prevailing winds
understanding of winds was crucial to European maritime exploration
fixed year-round (unlike Indian Ocean monsoons)

Summary

before this period, many of the voyages that Europeans took would have been impossible
Europeans built on the knowledge of the travelers from Unit 2 (Networks of Exchange)
the most important things they picked up were astrolabes (Islamic) and trade wind maps to know how/when to get from place to place
Europeans disrupted trade networks around the globe
Europeans become major power of world

4.2 Causes and events

European disadvantages

inferior trade position
resentment from having to use Muslim intermediaries for access to Asian goods
looked towards Atlantic Ocean for better route to Indian Ocean trade
religious concerns
Catholic missionaries sought to expand Christendom (Reformation)
persecuting minorities (Protestants) sought religious freedom
competition over trade/territory
Venice held monopoly on trade in Mediterranean
other European states resented Venice’s wealth and power
Ottoman Empire encroaching into Europe
losing territory (and Christians) to Muslim empires
land = power

European advantages

government sponsorship
Portugal
Prince Henry the Navigator
financed expeditions around Africa to find a sea route to Indian Ocean
wanted to expand Portugal and Christendom
Bartholomeu Dias
sailed to and discovered Cape of Good Hope (Africa, 1488)
opened way for European ships to sail to Asia by circumnavigating Africa
Vasco de Gama sailed to India (1498)
Spain
Columbus tried to find a route to the “Indies”, arrived in Caribbean (1492)
Ferdinand Magellan
first recorded expedition to circumnavigate the globe (1519-1522)
did not survive entire journey
irrefutable evidence that Earth is round
landed in Philippines
John Cabot (English)
sponsored under King Henry VII to find westward route to Asia
ended up in the New World
instrumental in initiating English exploration and colonization in North America
Henry Hudson (English; initially sponsored by Dutch)
driven to find northwest passage to Asia
claimed Hudson River for Dutch in what is claimed as New Amsterdam (New York)
later worked under various trading companies
Jacques Cartier (French)
explored North America, particularly Canada
claimed Canada for France
advanced France’s exploration, claims, colonization of parts of North America

Summary

Europeans had new navigational technology (4.1)
Spain and Portugal went first, splitting the world with the Treaty of Tordesillas (Brazil and rest of Americas respectively)
new: British, Dutch, French
trading post empires: not massive, just along coast
arrivals accompanied by death, disease, genocide

4.3 Columbian Exchange

Transfer between Eurasia, Africa, Americas

New World → Old World
crops
maize, potato, cassava, sweet potato (highly caloric)
tomato, capsicum, cacao, tobacco (become culturally important)
diseases/medicines: syphilis, quinine (used to treat malaria)
innovation: rubber
Old World → New World
crops: wheat, rice, sugar, coffee, fruits (grew well in New World soil)
domesticated animals
horse, cow, pig, sheep
upset ecological balance, ate/destroyed native crops
major changes to indigenous cultures (horses)
diseases: smallpox, influenza, typhus, malaria
impact favors Europeans
cheap crops fueled European population growth
60 million (1400) → 390 million (1900)
American colonies provide space for excess population
wealth of colonies sparked Industrial Revolution

The Great Dying

natives lacked immunity to European diseases
90% of indigenous population killed by disease
sometimes even before European arrival
impact
allowed Europeans to easily conquer and quickly outnumber
forests regrew; animal populations rebounded from hunting
shortage of labor: Europeans turned to African slave trade

Summary

Old World and New World met for first time
exchange stuff
not an event, just exchange
disease, livestock for Native Americans
caloric foodstuffs for Afro-Eurasians

4.4 Maritime empires established

Slavery before the New World

Trans-Saharan trade provided slaves to Middle East and Indian Ocean
operated within the Islamic World
southern Russia: Slav was basis for “slave” in English
slavery came in many forms
Rome: slaves earned freedom, became politicians and business owners
Egyptian Mamluk: slaves became rulers
Indian Habshis: slaves became military strategists
Islamic world: female slaves preferred as domestic servants
slave status sometimes inherited, sometimes not

Slavery in the New World

most slaves came from West, Central Africa
12-15 million over 400 years
80% of slaves (mostly male) sent to sugar colonies in Brazil, Caribbean
chattel slavery: slaves were legally property, not humans
slavery became associated with race (African) for the first time
status as slave was inherited across generations

Atlantic Slave Trade

Why Africa

Europeans cut off from Slavic slaves by Ottoman expansion
Pope gave permission for Christians to enslave non-Christians
indigenous peoples of Americas killed off by diseases
European indentured servants were expensive and temporary

Middle Passage

second segment of the Triangle Trade (80 days long)
packed ships to maximize profits
male slaves chained together to keep from jumping overboard
special nets to catch any that decided to jump together
kept below decks in specially-built holds; crammed together
mortality rate: 14%
disease
starvation
dysentery (infectious viral diarrhea)
whipping
occasional executions

Effects

some African nations prosper (initially)
Asante (West Africa), Kongo (central Africa) were largest source of slaves
conquered neighboring tribes, sold slaves to Europeans in exchange for firearms, European goods, alcohol
disrupted most African societies
sex ratio imbalance
labor demands on women increased
economic stagnation

4.4-4.5 Maritime empires established and maintained

Portugal

Europe sought more trade with Asia
most trade went through Muslim middlemen, Venice
Portugal was first to seek alternative trade routes
Bartolomeu Dias (1488): sailed to Cape of Good Hope (southern tip of Africa)
Vasco da Gama (1498): sailed up coast of East Africa to India
interested in spice trade: cinnamon, cloves, nutmeg, pepper
Portugal sought to dominate trade in Indian Ocean by force
caravel ships were faster and better armed than merchant ships
developed a trading post empire (controlled commerce, not land)
