Finding a sea route to Asia
Two problems sailors faced before the 1400s
a. They did not have good ways of knowing where they were if
they got beyond sight of land.
b. The maps were poor and their ships were too slow to make long
The invention of the astrolabe
and the caravel
helped sailors to
travel faster, farther, and more safely.
The Portugese invented the caravel.
The Early Explorers
The Spanish Sail West
Columbus' believed that the earth was round. This
caused him to think he could sail west to find Asia.
Columbus did not know when he sailed west to
find Asia that the earth was much bigger than he thought.
Columbus called the Native Americans Indians
because he thought he really had reached the East Indies.
The effect of Columbus' journey was to start the
Age of Exploration
(the period of time when Europeans were exploring new lands).
The Portuguese Sail South and East
The effect of da Gama's decision to sail south
and east was that he found an excellent trade route that gained wealth
The Spanish Continue to Sail West
Spanish explorers still sailed west believing
that this would lead them to Asia.
Balboa discovered the Pacific Ocean in 1513.
Magellan's expedition proved to Europeans that
the world was round.
Da Gama's route to Asia was better than Magellan's
because it was safer and shorter.
Perspectives on the New European Trade Route to Asia
European governments viewed the discovery of a
new trade route to Asia differently than the Muslims
While the Muslim government made less money since they were selling
fewer Asian goods to Europeans, European governments supported
the new trade route because they earned taxes from trade.
Exploring the New World
Spain and England worried that Portugal would use
its growing wealth to try to dominate
them when Portugal started to use the new sea route to Asia.
Spain and England attempted to solve their
problem by exploring the Americas to get wealth.
Spain explored both North and South America.
England explored a part of North America.
Portugal explored an area in South America (current
