Implications of
“Renaissance” for European exploration: Europeans had discovered the power of the human mind to
manipulate the world around them. Aggressive aspect to the new emphasis on man For Machiavelli, goal of princes
was to successfully maintain power – not to exercise this power in a Christian
way. Even on a personal level, legitimate goals of life
(according to humanists) were to succeed – to raise your status and gain money
and power - not to devote yourself to God. Greed
now seen as good for the state (Machiavelli – prince should promote economic
enterprises) The questions for us today are Why not the
Arabs? Why not the
Chinese? I. PRECONDITIONS OF EUROPEAN
EXPLORATION: ANCIENT GEOGRAPHY AND NEW TECHNOLOGY A. But in order to do so,
Europeans had to get over some serious obstacles to ocean navigation: The
belief that if you sailed over the ocean, you would fall off the end of the
earth. And
difficulty navigating on the open sea. In the Middle Ages, Europeans had conceived of the earth
like this: IMAGE OF
ISIDORE'S TRIPARTITE MAP The earth
was a circular disc (rather like a frisbee) All the
land was surrounded by water (the ocean) - and if you crossed this ocean, you
fell off edge of world. Maps were
oriented to the East (not the North) because the East was where Jerusalem was. Only three
continents were depicted - Asia, Africa, and Europe (no knowledge of America) The water
bodies which divided them were the Mediterranean Sea - the Nile river, and the
Hellespont/Black Sea - shown here as forming a Cross. You can see how religion dominated the way people viewed the
world in the Middle Ages - Now actual experience forced people to modify this idealized
tripartite schema during the high Middle Ages. Here is a 11th
century map . It is also oriented to the East;
the Ocean flows around on the rim of the Frisbee But the bodies of water are more
realistically portayed - you can see the Nile, the Adriatic, etc. Still, this map is horribly inaccurate. Doesn't
show the existence of China India is
much too small Subsaharan
Africa is almost unknown - except for mythical "Antipodes" What allowed Europeans to get a more accurate knowledge of
geography was the rediscovery of classical geography. B. Rediscovery of ancient geography - Ptolemy During the 14th and 15th centuries,
when all of these other classical texts were being rediscovered in Europe, the
classical geographers were also being discovered. The Greeks and Romans had a better idea of the shape of the
earth than medieval Europeans (or Moslems) - For one, the ancient Greeks had known that the earth was a
globe, not a flat disc. - And they better understood the shape of Africa and Asia
(in part because both the Hellenistic and Roman Empires had included North
Africa and western Asia). Ptolemy The most important ancient geographer had been Ptolemy - a scholar from Alexandria who wrote in 2nd century AD -
during the Roman Empire. IMAGE I IMAGE II. How does
Ptolemy's map differ from the medieval map? (recognizes
that earth is sphere - though for purpose of map, modifies sphere) Ptolemy's
most important contribution was imposing a grid-pattern on the globe in order
to aid navigation - origin of our
longitude and latitude (shape of continents - Europe,
Asia, Africa more to scale No
knowledge of Americas Belief that
land - not water - circles south of Africa. By 14th century - Ptolemy was being to read again
in Europe. Impact on navigation: Merchants and princes now knew that
the earth was a globe - not a disc: You wouldn't fall off the globe if you
sailed the oceans. Sailors began to use latitude to
judge distances - (they could measure latitude by the angle of the sun) - this
allowed them to sail open oceans (instead of just hugging the coast). And some navigators suspected that
it would be possible to get to Asia by going west as well as east. Christopher
Columbus would be one of them. C. NEW TECHNOLOGY of 14th
and 15th centuries In addition to rediscovering Ptolemy, European exploration was
made possible by new technology. Throughout most of human history
- new technology traveled from Asia and Africa into Europe - not the other way
around. Only in the 14th
century, did Europeans begin to make significance technological innovations
(though they still tended to get original idea from the East) Technology that helped European
exploration: - Gunpowder: We've already
discussed gunpowder: Invented by the Chinese, turned into effective weapons
by the Europeans (cannons
will be an important element in the success of European world exploration) - Portugese ship innovation: the caravel new type of ship was developed,
the caravel, that combined cargo capability, manoeuverability and
seaworthiness, It used a new
sort of sail adapted from Arabs which could tack against headwinds To sum up preconditions for
European world exploration: Motive - to
bypass Ottomans and get eastern luxuries Geographical
knowledge: earth was round; latitude
and longitude to more accurately locate yourself on open sea Technology: ocean-worthy caravels; compass; printed maps
and charts; cannons to protect cargo II. PORTUGESE EXPLORE AFRICA AND ASIA Exploration of new trade routes was, however, an expensive
business - too expensive for any one merchant to finance. The explorers needed royal patrons - and the monarchs of
Portugal and Spain proved the most willing to explore the Atlantic. Why the Portugese and Spanish, instead of the English,
French, Italians, or Germans? partly
because Portugal and Spain had Atlantic coastline - natural direction for them
to expand Partly
because English and French occupied fighting one another (Hundred Years’ War);
Italy and Germany too disunified to have monarchs powerful enough to finance
such voyages. Portugese
and Spanish monarchs interested in financing voyages both for profit - and
conversion - the explorations of the world were as much Crusade as trading
expedition A. AFRICA Now, Africa is not far from Europe - so why didn't Europeans
and Africans make contact before? Geography of Africa
(MAP) To some extent, they had North Africa (red part on map) is on the
Mediterranean Sea - and had been part of the history we've been talking about
this in course (part of Roman Empire and later Islamic civilizations) The
Egyptians had created one of the earliest and greatest ancient civilizations. North
Africa had made up part of both the Roman and Moslem empires – North Africa is where many of the Moslem scientific and
philosophical advances originated. But the Sahara desert separates North Africa from
rest of Africa. Neither the
Romans or later Europeans could manage to cross the Sahara. The Arabs
were able to - which is reason why some of subsaharan Africa would become Moslem
during the Middle Ages. But even
Arabs found Africa difficult to explore as they approached the equator and the
tropics What was result of all this? Most
Africans were isolated from Europeans, Asians, and North Africans before the
early modern period. This (as it
did in America) will put them at a disadvantage technologically - for humans
advance technologically by borrowing and competing with their neighbors Henry the Navigator, king of Portugal, initiated the
exploration of the Atlantic coast of Africa in 15th century. He wanted to find a new sources for spices, gold, and other
eastern luxuries - but he also wanted to find Christian
allies against the Moslems (there was a story popular in the Middle Ages that
there was a Christian kingdom somewhere in Asia or eastern Africa) By the 1430’s, the Portugese were sailing up and down the
west African coast - setting up trading stations, and trying to find something
to trade. They found ivory, gold, food items (like rice), and slaves.
This is the beginnings of the African slave trade – which
will eventually, as you know, have important repercussions in America. Now slavery had existed as long as human history - but it
had by and large disappeared from Europe itself by the high Middle Ages. This was partly because the Christian church objected to
enslaving fellow Christians - and Europeans weren't rich or powerful enough to
enslave non-Christians during Middle
Ages. During the Middle Ages, it was more common for Europeans to be sold as slaves to the
Middle East. Our own
(and the Arabic) word "slave" comes from word "Slav" - for
the Slavs in 9th and 10th century were the main Europeans
exported to the Islamic world (their paganism made them legitimate trade items) Why Africans? But with the discovery of the Americas and the western coast
of Africa - Europeans found non-Christian populations they were capable of
enslaving. It is important to realize that slavery was not yet racially
defined - "White" people and native American slaves were
also sold in Europe in the 15th century. But native Americans tended to die because of their lack of
resistance to European to diseases, Africans were physically strong – they had already built
up immunities to smallpox, measles, and so on. The other main reason
Europeans started to get so many of their slaves from west Africa were
its relative poverty and political disunity. Slaves could be bought cheap in western Africa - (the people of India, China, and Islamic world, who were
richer than the Europeans, would have charged too much, even if they had been
willing to sell) Also, it was much harder to get slaves from regions with strong
governments. Most governments wouldn’t allow
their own citizens to be sold as slaves. They would, however, sell their
captured enemies (this is what happened in medieval Europe). In west Africa, the many small kingdoms and tribes were
often fighting one another. The Portugese would buy slaves from native African rulers –
who would raid enemy tribes to get them. The Portugese and later European slave traders would also
capture slaves themselves when they could away with it. (MAP OF
MAIN AREA OF SLAVE TRADE) So for this combinations of factors - Africans' resistance
to disease, their poverty, their political disunity - west African became main
source of slaves for Europeans. By the middle of the 15th century, the Portugese
had sold several thousand black Africans in Europe – where they were regarded
as exotic luxuries at first. The export of African slaves to Europe itself would only
last about a century – By the mid 16th century, most of the slaves were
being sent to the new colonies in America and the Caribbean, not to Europe. This is why many of the countries
of Latin America (Jamaica, Brazil) have populations with mixed African, native
American, and European ancestry. But their goal was still to get to India - where spices,
silk, and so on would be found. 1488: Bartholomeu Dias rounded Cape of Good Hope (because a
storm blew him off course)- proving that it was in fact possible to travel
around Africa by sea. •1493: First Portugese explorer reaches Ethiopia
Portugese relations with eastern African states European relations with other east African states were less
exploitative than in western Africa. They traded spices and gold - but not many slaves. This was partly because some East Africans were Christians: Ethiopia
had been Christian for as long a period as Europe had - missionaries had
reached it in late Roman period. Ethiopians were literate– if you
learn Ethiopic, you could read saints’ lives, chronicles, and poetry written by
Ethiopians during the medieval period (other sub-Saharan Africans – like Mali –
were also literate – see Bulliet) When they met the Ethiopian king,
the Portugese thought they had discovered new allies against the Moslems. Ethiopian kings entered into
diplomatic relations with representatives of king of Portugal. Even the non-Christian eastern Africa states were better
able to defend themselves: They were
more politically unified (Swahili empire; They had
impressive fortifications.. And Africans of eastern coast were used to traders
visiting them - they were part of an Arab trading network much older than the
Portugese. PORTUGESE AND INDIAN OCEAN TRADE In 1498, the Portugese explorer Vasco da Gama reached India
by going around Africa. (first European
to reach India by circumnavigating Africa; Diaz had circumnavigated Africa a
few years earlier by accident) He had
succeeded: he had found a new route to India - which bypassed the Moslems. But Gama's first attempts to trade in India were not a
success. The first people there he spoke to were two Moslems from
North Africa - who greeted him Spanish with "May the Devil take you! What brought you here?" (then they
started to talk about European politics) These Arab merchants weren't surprised that the Portugese
had managed to go around Africa - they had suspected it was possible, but
didn't think it was worth the trouble. Then Gama showed the rulers of Calicut the goods he
had brought to trade: cloth, beads, lumps of sugar The Indians laughed at him: they didn't want any
anything the Europeans had. Two years later Gama went back to India - this time with a
Portugese squadron armed with cannons. In Indian Ocean, - he attacked a Moslem ship (carrying pilgrims
to Mecca), and burned it with gunpoweder - along with its crew of 400 plus men,
women and children. When Gama got to India, he demanded that the ruler of
Calicut surrender. To encourage him, he cut up bodies of captured traders and
fishermen and sent baskets of their hands, feet and heads to the king (Samuri)
of Calicut. This was the beginning of the Portugese trading empire in
Asia. Soon Portugese fleets sailed regularly to the Indian Ocean
by going around Africa. By means of their cannon carrying ships, they got control of
a few ports of the western Indian coast (Bombay, Goa). They never conquered much territory: Europeans wouldn’t conquer India until much
later - but Because of their gunpowder and cannons, the Portugese
conquered some key ports. To convince the Indians to trade with them, they acted as
middlemen for transporting Asian goods (i.e. from Persia to India) rather than
selling European goods – which no one wanted yet. With the profits from this trade - the Portugese would buy
eastern goods to sell in Europe. Soon after reaching India, Portugese started to sail to East Indies and China: Very soon after Gama's voyage, the
Portugese were trading with East Indies
(Indonesia) 50 years later - by 1557 - they were in eastern
China; and Japan. Important point: it was Europeans use of force that
enabled them to penetrate Asian trade routes, not the goods they had to sell or
any special expertise at navigation (Moslems; Chinese equivalent here); they by
and large were just plugging into a preexisting trade system. III. NEW WORLD The Americas were different; Europeans first peoples of Old
World (Europe, Africa, Asia) to reach them. A. Columbus and the discovery of America Columbus was an Italian, from Genoa - of possibly Jewish
ancestory - with a Portugese wife. He had studied the
ancient Greeks textbooks on geography (Ptolemy) and also knew how to use the
new technology of seafaring (compass, ships with multiple sails). He started his career sailing Portugese ships down coast of
Africa. But Columbus wanted to lead an expedition west - He believed that if you sailed west
you would reach India – (he was right, but he didn’t know
that another continent – the Americas – blocked the way) -Columbus’ expedition Columbus first tried to get the king of Portugal (and then
France) to finance his voyage. They refused - so he turned to the monarchs of Spain. The queen of Castile (Isabella of Castile) and the king of
Aragon (Ferdinand of Aragon) had just married - uniting Castile and Aragon into
one kingdom - the kingdom of Spain. Isabella and Fernando were bent on furthering the glory of
Spain and Christianity: They agreed to finance Columbus' voyage - In 1492 (the same
year Spain expelled the Jews), Columbus set out for what he hoped would be
Asia. He was
supposed to claim any territory he found for the crown of Spain. He landed in what he thought was the Spice Islands near
India, actually the West Indies – the Bahamas. He traded with the native Americans
- "Indians" - during his first voyage (trading beads for gold) During his second voyage, he
brought missionaries and captured slaves Columbus thought he had invented a new route to India. But in the 20 years after his voyage, other explorers
figured out the true significance of his discovery: Two new continents – inhabited by
people who couldn’t match the Europeans militarily. NATIVE AMERICANS BEFORE COLUMBUS If you were to describe native Americans before Columbus –
how would you do it? Were the
native Americans literate? (WRITE IT DOWN?) Did they
use metals like iron? Did they
live in cities (i.e. settlements of thousands) or just villages and nomadic
tribes? The answer varies depending on what Americans you are
talking about: Some native
Americans had been able to write since the early Middle Ages - Maya in Honduras ; early Mexicans
hadwriting. In Mexico,
and South America, complex civilizations still existed when Europeans arrived -
with books, cities larger than European cities, and sophisticated road systems. What the
native Americans didn't have was iron weapons, horses, gunpowder, or resistance
to European diseases. Native Americans of Bahamas The people Columbus encountered in the West Indies were among
the less technologically advanced of the native Americans. They could farm – i.e. they had had their “agricultural
revolution” - but they did not have
cities, writing, or complex government. Columbus’ description of their civilization in Letter from
the First Voyage 1493: Maya A third American civilization had existed long before the Europeans had arrived - the Maya in Central America,
perhaps the most appealing of pre-Columbian American civilizations. Just as you need to look at the Greeks and Romans to
understand how Europeans got to be the way they are, in America, you have to
look at the Maya. The Maya had their Golden Age in the 6th to 9th
centuries – i.e. at the same time as the Early Middle Ages in Europe. The Maya lived in Central America (Guatemala and Honduras),
in a tropical rain-forest. Somehow, in this dripping, insect infested and disease
ridden environment, they built large cities, created a beautiful art and
architecture, and wrote books. (They also invented hot chocolate – for which I am
grateful). We are just beginnings to learn the history of the Maya,
because only recently have scholars been able to read much of their script. (OVERHEAD
OF GLYPHS) One of the things historians would like to learn is why the
Maya civilization collapsed – for it seems to have done so in the 9th
century. Perhaps party because
of invasions from the Mexico by people who could use metal weapons (they
Maya only used tone). After the 9th century, the Maya survive as a people
– they still exist today – but centers of civilization moved elsewhere, to
peoples who adopted much from the Maya. The two later complex societies in the Americas were the
Incas of Peru, and the Aztecs of Mexico. - Aztecs (Mexica) The Aztecs in Mexico had the potential to put up more of a
fight. (Aztecs is modern 19th century term for these
people, not what Mexica called themselves). The Aztecs lived in central Mexico – where they had built up
a large empire in the 14th and 15th centuries, stetching
from Mexico to Panama. Unlike the people of the Bahamas, the Aztecs were warriors. IMAGE They were also literate: They had pictographic writing – similar to
hieroglyphics. IMAGE OF
BOOK In these books, the Aztecs recorded years and times; days
and feasts, dreams, and omens; victories and the
conduct of wars; the succession of principal lords, bad weather conditions, noteworthy signs in the sky Unfortunately, only a few of their books survive - because
Spanish burned them. In addition to writing, the Mexica had cities. Urban society: Tenochtitlan Their capital was what is called today Mexico City – on Lake
Texaco (Tenochtitlan). Mexico City under the Aztecs had a population of around 100,000
– enormous by European standards. The Spanish were impressed by the city’s size, splendor, and
wealth – especially all the merchants selling their wares. Human sacrifice But the Spanish were horrified by the altars to the gods
reeking with human blood – for the Aztecs sacrificed captured enemies, and ate
them. The Aztecs main goal in warfare was to capture as many men
as possible. As many as 20,000 captives a year were brought to Mexico
City. Some of these captives would be ritually sacrificed – first
a captive was slowly killed and decapitated, then the Aztec who had captured
him drank his blood, and then the captor’s family ate a stew composed partly of
little pieces of the captive. The Europeans of the 16th century were disgusted by this behavior. However, the Aztecs ended up killing a lot fewer men than
died in European wars, and they honored their victims – especially those who
showed courage when dying. - Incas The Incas were the other great empire in the Americas when
the Europeans arrived. The Incan empire was in South America - centered in the
Andes mountains of Peru. The Incas were not literate in the usual sense; instead of writing
they used colored cords tied into complex knots to send messages and keep
records. This was enough to allow them to build a great empire in
South America. They connected this empire with road systems built through
the mountains - - Las Cases thought only Roman roads could compete with them. IMAGE The roadway represents a considerable feat of engineering,
including even an 8m tunnel section where the Inca engineers widened a natural crack in the rock into a
tunnel large enough to allow the passage of men and animals What impressed the Europeans most was the socialist
organization of the Incas. All produce belonged to the state – farmers gave their harvests
to central granaries. Then the state would redistribute food, clothing, and so on
to the people. Native Americans in general did not have same concept of
private property as Europeans (who inherited theirs from Romans) European conquest of the native Americans By the mid 16th century, the Spanish – with the
Pope’s approval - had conquered the Bahamas, the Incas and the Aztecs;
Portugese will conquer Brazil. Why so successful at conquest in Americas, while not very
successful in Africa or Asia? Comparison of Aztec (the most warlike Americans) and
European warfare: Capture was the main goal of Aztec wars; while killing
the enemy during battle was the goal of Europeans. The Aztecs also lacked key military technology: No
horses (the American horse had been
hunted to extinction long ago) No iron
weapons – still used fling, obsidion No
gunpowder (but matters rarely got that far)- Above all, Aztecs had no resistance to European disease -
and were dying by the hundreds of thousands soon after Europeans' arrival. In the early 16th century, a few hundred
Spaniards under Cortes ended up taking Mexico City and eventually the entire
Aztec empire. - Biggest European ally in Americas: Disease Europeans - thanks to thousands of years of fighting and
borrowing from other civilizations in the Old World - had superior military
technology to the native Americans. But weapons were not the only thing which helped the
Spaniards defeat the Aztecs – or the Incas, and all of the other native
Americans. The most effective conquerors were European bacteria and
viruses. Native Americans had been isolated from the rest of the
world for tens of thousands of years. They had few infectious diseases of their own (due to
scarcity of domestic animals) and no resistance to measles, small pox, mumps,
cholera – all the nasty diseases which Europeans usually had as children (and
we vaccinate ourselves again). Cortes and his few hundred men only took Mexico City so
easily because small pox had got it first - When he entered the walls, he found a city of corpses. It is estimated that between 1519 and 1568 the population of
Mexico alone went from 30 million people to 3 million people (REPEAT) This is a decline of 90%
- which makes the Bubonic Plague in Europe seem like a bad cold. As a result of the introduction of European diseases in
addition to military conquest, the civilization of the Incas and the Aztecs
disappeared. Even the Aztec books were burned – since the priests
considered them the work of the devil. The civilizations of the Bahamas were even more completely
destroyed. This is where the Europeans will set up their first gold
mines and slave plantations. The local population quickly started to die out as a result
of mistreatment, disruption of agriculture, and disease. African slaves were imported as early as 1502 as a new labor
supply. Legacy of the native Americans Except for what archaeologists can recover, the high
culture of the native American civilizations disappeared. We can’t talk about borrowings in science, math, literature,
and so on from the Aztecs and Incas. However, as far as daily life, Latin American culture is a
blending of European and native American traditions. Native Americans languages survived as well as popular art
and architecture. And the whole world adopted native American foods – the
potato, tomato, chocolate and so on , Foods which were created by many generations of skilled
farmers – the people we usually do not
talk about in history courses. From the European perspective, the discovery of the new
world was a good thing. 1. Politically, European kingdoms like Spain, Portugal, and
eventually England and the Netherlands – began to create overseas empires. This increased both their wealth and influence at home. And provided a frontier for European colonists to settle 2. Wealth: And another product of the New World – much for valuable to Europeans in the 16th
century than to us – was gold and silver. New mines, not yet exhausted by mining, were found in the
Americas. Sugar plantations in the Americas, worked by slave labor -
would make many European families rich. 3. Food: the
products of the New World changed the way Europeans (and eventually Americans)
ate. Imagine life without tomatoes, potatoes, corn, bananas, or
worst of all, chocolate. All of these foods – tomatoes, potatoes, corn, bananas, and
chocolate came from the Americas. IV. The question to end with: why was it the Europeans who
became the explorers of the world? Why not the
Arabs? Why not the
Chinese? Both Arabs
and Chinese had better technology earlier than the Europeans, were wealthier,
were more politically unified? To answer this
question (why Europe?) - I'd like to compare Chinese attitudes towards world
exploration. China around 1500 AD was the most centralized and populous
state in the world. China had cities, complex government structures, a
sophisticated philosophical and religious tradition. Social mobility in China was through education - not birth
or wealth: By becoming
educated - you could become part of the administrative elite. During the Middle Ages, the Chinese had invented many things
the Europeans would only get during the Renaissance – printing with movable
type, paper, gunpowder, the compass. The technical quality of Chinese ceramics (“china”) and
textiles was superior to European - and would remain so for centuries. And when the Portugese arrived, an energetic new dynasty
ruled China – the Ming dynasty –( in power since 14th
century) World exploration under Ming dynasty In 15th century, Ming rulers engaged in some
geographical exploration similar to the Europeans – Between 1405-33, the rulers
sent out maritime expeditions under admiral Cheng Ho. These Chinese ships (called junks) explored East Indies - Java, Sumatra, Ceylon. They went to the Persian Gulf and Egypt - the Red Sea. And went down east African coast to Somaliland and Zanzibar. So before Portugese reach these places - Chinese have got to
them from other direction. These Chinese expeditions were larger than any European
fleets - 37,000 sailors; 317 ships. But one thing which helps explain why Chinese didn't
continue to be world explorers was purpose of expeditions
Not conquest ; not to increase nation's wealth not to convert people to
Christianity or to learn new science - Chinese purpose was to display splendor and power of Ming
dynasty: Ships would
just arrive, show off, and then leave Chinese didn't actually want anything from
foreigners: They
thought they had the most civilized, admirable civilization on earth - so why
try to acquire new things? In 1433, Ming rulers stop these voyages to rest of the world Later on the 15th century – they forbade any
further Chinese ships from going abroad, and stopped building ocean going
vessels. Why Chinese consciously choose not to take full advantage of
their inventions and strength? Value of cultural stability: They valued cultural stability above all – and China
had the most long-lived, stable civilization in the history of the world. Anything which might disrupt the
Chinese social order – new military technology, or foreign contact – was avoided. The paradox of China is that its
people did not exploit their own inventions fully: Chinese
invented gunpowder, but never made cannons. sailors used
compass before anyone else; but didn’t explore Pacific (next to them) Chinese
had mechanical clocks first, but the Jesuit brought better clocks when they
arrived in 16th century. Chinese
invented the printing press first - but Europeans in 15th century
will make printing press vehicle for first mass distribution of literature in
world history. So why did the Europeans become
the world explorers? Europeans by 1500 - were eager for
new knowledge, new goods to trade, new lands to explore and conquer: Even
if these discoveries disrupted their social and mental order.
The first region the
Portugese explored was western Africa.
