Three Worlds Meet (Beginnings to 1620)

World History

This collection uses primary sources to explore the Columbian Exchange of ideas, plants, diseases, and people after the arrival of Christopher Columbus in America.

A drawing of Christopher Columbus.

This drawing shows Christopher Columbus being sent by King Ferdinand and Queen Isabella of Spain to find a western sea route to China and India. Instead of discovering the route, Columbus and his crew accidentally came upon the Americas. The drawing depicts excitement and eager preparation for the voyage. 

An illustration of Christopher Columbus’s initial meeting with Native Americans.

This image shows an artistic interpretation of Columbus’s initial interactions with Native Americans. Columbus, his men, and his ships are on the left while the Native Americans appear on the right. The drawing portrays big differences between the body positions and clothing of the two groups.

An excerpt from the 1815 book The *History of the Small Pox* by James Carrick Moore.

In this excerpt, Moore describes the calamities and deaths caused by smallpox in the fifteenth and sixteenth centuries as a result of European colonization of the Americas. Smallpox was one of the most devastating consequences of the Columbian Exchange. Diseases brought to the Americas by Europeans after the Columbian Exchange caused a population decline among Native Americans that was the largest in human history. 

A drawing of a sugar plantation.

This image of a sugar plantation shows Africans harvesting sugarcane under the close supervision and watchful eye of a European overseer. African slavery, another devastating effect of the Columbian Exchange, increased substantially with the introduction of sugarcane production in the New World.

An excerpt from *The Potato*, a 1917 book by Arthur W. Gilbert.

Gilbert discusses the origins of the potato and its transfer from the Americas to Europe. The potato originated in multiple places, but was first cultivated in Peru by the Incas some time between 8,000 BCE and 5,000 BCE. In 1589 CE, Sir Walter Raleigh introduced the potato to Ireland, where it became a major staple crop.

An 1891 photograph of a traditional Native American cow shield.

Cow shields were used by Native Americans as a defensive and protective armor for warriors on horseback. Cow shields were especially prominent amongst the Great Plain Indians. Columbus brought the first cows to the Americas from Europe in 1493. As a domesticated animal, cows were primarily a food source for Native Americans. Additionally, cowhide was used for clothing, tents, and shields. The cow shield in this photograph has green spots on white ground, with blue, red, and yellow lines across center.

An excerpt from a 1672 book describing plant and bird discoveries in New England.

These excerpts from *New England’s Rarities Discovered in Birds, Beasts, Fishes, Serpents, and Plants of That County*, by John Josselyn, provide evidence of plants being exchanged across hemispheres. Josselyn, an Englishman who made at least three trips to New England in the seventeenth century, was fascinated by the plant and animal life in the region. His published account is one of the earliest and most complete descriptions of the biodiversity in colonial New England. Among plants being exchanged across hemispheres, Josselyn notes that the dandelion “ha[s] sprung up since the English planted and kept cattle in New England” (137). He also notes that cabbage and lettuce from England grow exceedingly well in New England.

An excerpt from an 1890 book on horse training.

This excerpt comes from *Horse education: A Treatise on the Origin, Characteristics, and Training of Horses* by Thomas J. Murray. Murray describes the origins of the modern horse, which he traces back to fossils of a prehistoric animal with three toes and a hoof from the Cretaceous period around 145 millions year ago. The modern horses of Mexico, South America, and North America can all be traced back to European colonization.

An Aztec codex prominently displaying maize, 1830.

Pre-Columbian Mesoamerican people groups (Aztecs, Mixtecs, and Mayans, e.g.) created codexes, textual records, that are one of the best primary sources for historical information about their cultures. This codex, *Thirteen Cities Paying Tribute to Aztecs*, was recreated in 1830 by Agostino Aglio. It reveals the importance of maize to the Aztecs. Maize, a corn that was first grown by indigenous people in Mexico nearly ten thousand years ago, is one of the most important crops to be “exchanged” in the Columbian Exchange. It can grow in nearly any climate; currently, under certain conditions, corn can produce a yield double that of wheat. After the Columbian Exchange, corn fed humans and livestock, contributing to population growth in many areas.

An excerpt from a 1994 book of cultural ecology discussing Spanish missions. 

In this excerpt from *A River Ran Through It ... : The Cultural Ecology of the Santa Clara Valley Riparian Zone*, Erin Reilly discusses the history of [Spanish missions](https://dp.la/primary-source-sets/sets/spanish-missions-in-california) and the environmental consequences of Spaniards’ presence on the California coast. Reilly describes how the Spanish missions introduced a shift in thinking, from the indigenous peoples’ view of the earth “as living and deserving of attention and respect” to the Spaniards’ view of the earth “as a vehicle of production” (41).

A photograph of a sweet potato plant, 1900.

Sweet potato cultivation spread to Europe in the fifteenth century as a result of the Columbian Exchange, but it had already spread to Polynesia, Hawaii, and other Pacific islands around the ninth century. In this photograph, one can see many features of the plant. The leaves and stem at the top of the plant would be above ground when the potato is growing, while the fibrous roots and storage roots at the bottom of the plant would be below the surface. The storage roots are the sweet potatoes that, during harvest season, require some heavy labor to dig out of the ground.

A fire pot depicting Aztec gods, circa 1325 to 1521.

This fire pot, also called a brazier, was used by the Aztecs to offer burnt offerings to their gods. The figure attached to the front of the brazier is a combination of the Aztec rain god, Tlaloc, and the corn god, Centeōtl. One of the most important deities among the Aztecs, Centeōtl reveals the significance and importance of corn in that society. As a result of the Columbian Exchange, corn also became extremely important in other regions of the world.

An eighteenth-century illustration of a tomato plant.

This illustration of the tomato plant was created by Giorgio Bonelli, an Italian, who painted this and many others featuring plants in the eighteenth century. This illustration highlights the significance of the tomato to Italy. Tomatoes were first cultivated by the Aztecs and Incas and introduced to Europe through the Columbian Exchange.

Overview

Historical evidence proves that there were interactions between Europe and the Americas before Christopher Columbus’s voyage in 1492. But Columbus’s contact precipitated a large, impactful, and lastingly significant transfer of animals, crops, people groups, cultural ideas, and microorganisms between the two worlds. In 1493, for example, on his second voyage, Columbus brought horses, dogs, pigs, cattle, chickens, sheep, and goats to the “new” world. Later in the 1530s, the Spanish conquistador and explorer Francisco Pizarro saw the potato in the Andes of South America and brought this crop to Europe. Bacteria and viruses, as well technological and cultural ideas, moved between the hemispheres, and Europeans forcibly transported enslaved people from Africa to the Americas to provide free labor. These transfers had a monumental impact on the development of our modern world. Alfred Crosby, who wrote an important 1972 book called *The Columbian Exchange: Biological and Cultural Consequences of 1492*, asserts that the commingling of plants, animals, and bacteria resulting from the Columbian Exchange is one of the most important ecological events in human history. 

This primary source set explores positive and negative consequences of this great shift, showing both instances of exchange and resulting instances of cultural, political, ecological, and biological imperialism.
