1 Objective 20: The Columbian Exchange

2 Should Columbus Day be celebrated as a national holiday?

3 Voyages of Christopher Columbus Under the sponsorship of the Spanish crown, headed for Asia by sailing west Landed in the Bahamas Made four voyages altogether Didn’t find gold or spices Did find a “new world”

4 Columbus Landing at Guanahani, 1492 1837-47 Rotunda, US Capitol, Washington John Vanderlyn, an American whose revolutionary sympathies had led him to study and work in Paris in the early days of the empire, executed this painting in the American Capitol in Washington. His theme was Columbus Landing at Guanahani, 1492, glorifying the arrival on this West Indian island of the historical figure who was regarded as the founder of the white and Christian Americas. His Indians crouch like wild animals, frightened and puzzled, and some of the explorer's Spanish sailors crawl on the ground, already hunting for gold.

5 The four voyages of Christopher Columbus. He “discovered” “Hispaniola” [Haiti/DR] and the “Indians.”

6 Seven Myths of Spanish Conquest “Exceptional Men” “The King’s Army”—Neither paid nor forced. “White Conquistadors” – Invisible Allies “Spanish Conquest” – Myth of Completion “The Myth of (Mis) Communication” The Myth of Indian Desolation The Myth of Superiority

7 What Really Happened? Disease Native disunity Weapons – guns, steel, horses, war dogs, tactical skills, especially the steel sword Culture of War Global context of an age of expansion

8 Pre-Columbian America. Pre-Columbian America had two great regions of trade and political power. In the north, the Aztec kingdom, centered on Tenochtitlán, dominated. The adjacent Maya of Central America were in decline. In South America, about 1500, the Inca dominated the Andes mountain regions, linking them together through an extensive system of roads.

9 Conquest of Mexico 1519-1521 conquered the Aztec empire with only 450 men How? –Superior weapons –“Divide and conquer” –Disease Hernán Cortés

10 Cortes with Doňa Marina a.k.a. “Malinche” Broken spears lie in the roads; We have torn our hair in our grief. The houses are roofless now, and their walls Are red with blood… Elegy for Tenochtitlan

11 Conquest of the Incan Empire 1530-40 conquered the Incan empire with only 600 men

12 The “Columbian Exchange” TE: “…the global diffusion of plants, food crops, animals, human populations, and disease pathogens that took place after voyages of exploration by Christopher Columbus and other European mariners...”

13 Three main aspects of the Columbian Exchange Biological exchanges Dietary exchanges Human migration

14 Biological exchanges Prior to Columbus’s voyages, Eurasia was “thoroughly diseased” and the Americas had been in relative “biological isolation.” Why? Contact among cultures of Eurasia had been much more intense over the centuries. Eurasians had a long history of domesticating animals—a source of disease.

15 Diseases exchanged: Eurasia  Americas: –Smallpox, measles, diphtheria, whooping cough, influenza Americas  Eurasia: –Syphilis?

16 Consequences of biological exchanges: Devastation of native populations of the Americas and Oceania. Within one century, some native populations declined 95%!!!! Images of Aztec smallpox victims.

17 Between 1500 and 1800 approximately one hundred million people* in the Americas and Oceania likely died of imported diseases. *The current population of the U.S. is 300 million so this was equivalent to 1 in 3 Americans living today.

18 Dietary exchanges Americas  Eurasia –“New World Crops- –Maize, potatoes, beans, tomatoes, peppers, peanuts, manioc, papayas, guavas, avocados, pineapples, cacao, tobacco Eurasia  Americas –“Old World” –Wheat, horses, cattle, pigs, sheep, goats, chickens The incredible potato!!!

19 Export of Tobacco from Virginia “Drug and Taste Revolution”


21 Consequences of dietary exchanges: More balanced diets globally Increased calories in Eurasian diets  the amazing potato and also maize Basis of “national” foods and customs  tomatoes to Italy, spices to China, horses and cattle to the Americas A surge in global population!

22 Population increases: World population: 1500: 425 million 1600: 545 million 1750: 720 million 1800: 900 million World population more than doubled in three hundred years!! This more than offset population losses due to disease.

23 World Population Growth, 1500- 1800 CE

24 Human migration The massive de-population of the Americas due to conquest and disease: Enabled European migration and colonization Compelled forced migration of slaves from Africa



27 Sugar and Slavery “Every ton of sugar represented a life; every teaspoonful represented 6 days of a slave’s life.”

28 African Slave Exports per Century

29 Destination of Africans in the Atlantic Slave Trade


31 The “Atlantic System”

32 Slave trade Transfers African culture to the Americas Between 1450 – 1850 it is estimated 12 million Africans were shipped across the Atlantic Ocean Portuguese and then Dutch, English, and French European agents made agreements with local leaders to traffic slaves Enormous profits – up to 300 % on a voyage Sugar plantation labor

33 Manila galleon route and the lands of Oceania, 1500-1800

34 European exporation in the Pacific Ocean, 1519-1780.

35 European trading posts in Africa and Asia, about 1700

36 European empires and colonies in the Americas c. 1700

37 Economic Impact Gold and silver from America to Europe – who uses it to buy Asian goods Rise of the European commercial class and decline of the aristocracy Europe becomes the center of the world market



40 Some long-term effects of the Columbian Exchange: Creation of a global economy for the first time in human history European colonization of the Americas European Empires-beginning of “westernization” Cultural changes – Latin America, Atlantic Civilization Global population growth Permanent depletion or loss of many native American and Oceanic cultures Uneven consequences around the globe

41 European exploration, 1450–1600. Spanish and Portuguese explorers and traders had established settlements in South America and the Caribbean by 1600, and commercial depots on the coasts of Africa, India, the Pacific islands, China, and Japan—at a time when English, Dutch, and French explorations of North America had just begun.

42 World exploration. The limitations on sea routes through the Middle East drove the trading nations of western Europe to seek alternate maritime passages to Asia. European navigators and cartographers rapidly built a map of the globe which included, by sailing west, the “New World” of the Americas and, by sailing south, a passage around Africa, linking with the Arab trading routes of the Indian Ocean. The voyages of the Ming Chinese admiral Zheng He were undertaken to demonstrate China’s strength even more than for trade.
