reconnected ecosystems that had
developed in isolation from one
another for thousands of years. In
the so-called Columbian Exchange,
lives and economies that had altered
only gradually over centuries were
suddenly transformed by the influx
of new crops, animals, technology,
and pathogens. Many of the effects
were unforeseen and misunderstood
by both Europeans and American
Indians at the time, but once the
first landing had been made, there
was no turning back.
Food and farming
When Europeans began to settle
in the Americas, they brought with
them their own domesticated
animals and foods. The enormous
range included citrus fruits, grapes,
and bananas; coffee, sugar cane,
rice, oats, and wheat; and cattle,
sheep, pigs, and horses. To cultivate
their crops and pasture their
animals, the settlers cleared huge
areas of woodland, destroying the
habitats of some native wild species
in the process, and unintentionally
contaminating American fields
with the seed of weeds such as
dandelion and sow thistle. The
exchange in the other direction
brought potatoes, tomatoes, sweet
corn, beans, pumpkins, squash,
and tobacco to the Old World, as
well as turkeys and guinea pigs.
The introduction of new staple
crops transformed lives on both
sides of the Atlantic. Potatoes and
maize, carbohydrate-rich and easily
grown, helped overcome chronic
food shortages in Europe and, along
with manioc and sweet potatoes,
spread on to Africa and Asia. In the

highlands of Mexico, eventually
became a fundamental food crop
for tens of millions of settlers. The
arrival of horses in the New World
was also revolutionary, permitting
more effective and selective
hunting, as well as facilitating
travel and transport.
Biological catastrophe
The most immediately devastating
impact of the Columbian Exchange
followed the introduction of new
diseases into the Americas. The
settlers and the chickens, cattle,
black rats, and mosquitoes that
accompanied them introduced
contagious diseases to a people
who had no biological defense
against them. American Indians’
immune systems were not adapted
to cope with alien diseases such
as smallpox, measles, chickenpox,
influenza, malaria, and yellow fever.
Once they were exposed to them,
they began to die in the hundreds
of thousands. Half the Cherokee
nation died in a smallpox epidemic
in 1738, and some other tribes
were wiped out entirely. European
explorers encountered and brought
back American illnesses such as
Chagas Disease, but the effect
on Old World populations was
negligible compared with the
consequences of Old World
pathogens in the New World.
Exchange economics
From the start, the Columbian
Exchange had a strong economic
driver. Commodities ranging from
gold and silver to coffee, tobacco,
and cane sugar were transported
on a vast scale, mostly to the
benefit of European traders and
plantation owners.
Very soon, slave trading became
a key part of this network too. The
movement of people from continent
to continent in vast numbers
provided a continual supply of labor
for expanding new economies at the
cost of unspeakable oppression,
misery, and early death to many
generations. The dramatic and
irrevocable changes brought about
on both sides of the Atlantic by the
Columbian Exchange continued
to shape lives for centuries. ■

Cultural exchange
New World peoples were using
stone-age tools, had no wheeled
vehicles, and few domesticated
animals when they encountered
Old World societies, who used
guns and alphabets, farmed
pigs, sheep, and cattle, and kept
bees. The huge cultural changes
that ensued, especially in the
Americas, were complicated by
the two societies’ very different
attitudes to the “ownership” of
nature and property; attitudes
that would have significant
consequences for future
American Indian–European
relations. The arrival of the
horse led to the emergence of a
new, nomadic American Indian
tribe that came to dominate the
southern Great Plains.
Christianity started to spread in
the New World, some elements
of which fused with pre-
Columbian beliefs in the old Inca
and Aztec territories. West
African religion also arrived,
while introductions such as
literacy and metal tools and
machines, brought advances in
education, agriculture, and the
evolution of warfare.
