Columbus Sails Across The
Stories of fabulous kingdoms and
wealth in Asia captured the
imagination of Christopher
Columbus, a sailor from Italy.
Columbus was convinced that
he could reach Asia by sailing
west across the Atlantic Ocean.
The Journey Begins
• Columbus asked King
Ferdinand and Queen
Isabella of Spain to pay for
an expedition across the
Atlantic Ocean.
• He promised them great
riches, new territory, and
Catholic converts.
• Ferdinand and Isabella
agreed and ordered
Columbus to:
– Bring back any items of value
– To claim for Spain any lands
he explored
The Journey Begins
• On August 3, 1492,
Columbus’s three
ships set sail.
– The Nina and Pinta

– Columbus sailed in the
larger Santa Maria.
• Soon, they passed the
limits of Columbus’s
maps and sailed into
uncharted seas.

ships landed on an island
in the Bahamas.

found a new route to
• Instead, he reached
another continent that

Predicting the Results of Exploration
Based on what we have
learned in this class,
what do you think
Christopher Columbus
found when he landed?
Columbus Meets The Native Americans

another island called
Hispaniola, where he
met Native Americans.
At that time Europeans
called Asia the Indies.
Since Columbus

of exploring, looking
for gold, and
collecting exotic
plants and animals,
Columbus returned
to Spain.

three more journeys
to the Americas
during his lifetime.
In 1504, Columbus
returned to Spain.
He died two years

Impact of Columbus’s Voyages
• Columbus’s
created conflict
– Both Spain and
wanted to add
these lands to
their growing
Line of Demarcation
• As a solution, Pope
Alexander VI,
originally from Spain,
drew a boundary for
Portugal and Spain in
This line, known as
the Line of
Demarcation divided
the Atlantic Ocean.
– Portugal could claim
lands East of the line.
– Spain could claim all
lands West of the line.
Treaty of Tordesillas
• The Portuguese king
believed that the Line
of Demarcation was
better for Spain.
To prevent war, both
countries signed the
Treaty of Tordesillas.
– Moved the Line of
Demarcation 800
miles further west.
– Gave Portugal more
opportunity to claim
lands unexplored by
other Europeans.
