Title: Ecological Imperialism


1
Ecological Imperialism
2
Ecological Imperialism
  • This is the story of how a few Europeans

Hernan Cortes
C. Columbus
3
Ecological Imperialism
  • with some nifty but basically cheap weapons

4
Ecological Imperialism
  • were able to conquer a powerful empire of 10-12
    million people in a few years.

5
Ecological Imperialism
  • It is the story of diseases like smallpox that
    killed more Indians than any Spanish gun

6
Ecological Imperialism
  • and it is the story of plants

7
Ecological Imperialism
  • and animals that transformed the American
    ecosystem and undermined Indian society and
    resistance.

8
I. The Role of Geography
9
30-12,000 BC, Ice Age Global Warming in reverse
10
Mostly, though probably boat (sites in Florida
before Alaska)
11
A. Invaders from Mars
  • When the Indians arrived in the Americas they
    might as well have been from Mars biologically
    the two worlds had been separated for millions of
    years? no competition, stupid prey? early success
    and pop. growth

12
B. The Environment Strikes Back
  • Global warming (hot, starving mammoths)
  • Hungry and effective hunters (high-tech spears)
  • Pleistocene overkill (extinction of almost all
    megafauna)
  • ? transition to agriculture (less healthy
    Indians, complex societies class divisions
    developed spread by women) no domestication
    of animals (wait for it)

13
C. Adaptation
  • Indians adapt to diff. climate zones (diversity
    between groups)
  • Trade between groups? individuals specialized on
    talents (diversity within groups)

14
D. Examples of Diversity
  • 1. Mississippian societies trade societies built
    around rivers dominate Wisconsin to Louisiana
  • Urban centers
  • Mound builders
  • Tied to Great Lakes (Algonquian Iroquois
    Atlantic)

15
Cahokia (30,000 in 1200 AD)
16
Animal Mounds
17
  • Cahokia collapses from over-farming, drought,
    competition from neighbors? disperse to plains
    and prairie villages
  • Replaced by Coosa metropole (GA)
  • Rise fall of metropolis-based societies
    Cycling

18
2. Anasazi
  • Ancestors of Hopi and Zuni in Southwest
  • Some of most populated areas in the world at
    their height Chaco Canyon and Bandalier Mountain

19
Chaco Canyon
20
Bandelier Mountain
21
Anasazi Collapse
  • Chaco Canyon collapsed in part because of a
    sustained drought? inadequate food surplus?
    unable to mobilize labor, religious ceremonies,
    trade? dispersion to smaller villages nearer
    water (Pueblos)

22
II. Europeans How did they do it?
  • A. The Traditional Explanations
  • 1. Superior technology
  • Steel weapons (swords and armor)
  • Guns (flintlock muskets, cannons)
  • 2. Written language
  • Superior communication abilities
  • 3. Conquest Religion
  • Catholicism motivated the conquistadores to
    conquer in the name of God

23
Problems with the Traditional Story
  • Spanish armor was as much an obstacle as an aid
    in the dense forests and heat of Mexico Aztec
    swords could decapitate a horse
  • Spanish guns were inaccurate and often misfired
  • Cannons were dramatic but ineffective against an
    enemy that did not fight in tight formations
  • The Aztecs had very effective communication
    systems developed over hundreds of years of
    conquest
  • Many of the conquistadores were not particularly
    religious men and were in it for the gold, not God

24
B. The Socio-Cultural Explanation
  • 1. Aztec Confusion
  • Cortes and his men seemed to fulfill the Aztec
    prophecy of the return of Quetzalcoatl, the Aztec
    feathered serpent god

25
  • Cortes used this misperception to his advantage.
    The Aztec emperor, Montezuma, upon hearing that
    Quetzalcoatl had returned, actually invited
    Cortes into the capital city of Tenochtitlan.

26
2. Divide and Conquer
  • Perhaps more importantly, Cortes used the
    Quetzalcoatl myth to recruit Indians to help the
    Spanish.
  • The Aztec empire, like all other empires, was
    built by conquering other peoples. The Aztecs
    demanded tribute from these conquered peoples,
    sometime in form of human sacrifice

27
  • Just as the Algonquians in the Great Lakes region
    eventually joined with the French for protection
    against the Iroquois (who then sided w/the
    English), thousands of conquered Indians joined
    Cortes in attacking the Aztecs.
  • Among those who joined Cortes was a woman named
    Malinche who served as guide and translator for
    Cortes.
  • Mayan princess, enslaved by Aztecs
  • Bears Cortes children believes saving Indians
    from Hell disease via conversion

28
C. Biological Warfare Invaders from Mars Redux
  • Unlike peoples in the Old World, Native Americans
    did not domesticate very many animals
    (Pleistocene overkill) in particular they did
    not have pigs or chickens.

29
  • Big germ killersinfluenza, tuberculosis,
    measles, smallpoxoriginally animal diseases that
    mutated and got picked up by humans who lived
    close to their food source.
  • Europeans eventually got immunity (after Black
    Death) Indians did not have the time? virgin
    soil epidemic

30
  • 1580, Thomas Hariot, Roanoke The Indians
    began to die very fast, and many in a short
    space in some townes about twentie, in some
    fourtie, in some sixtie, in one sixe score,
    which in trueth was very manie in respect to
    their numbers....The disease also was so strange
    that they neither knew what it was, nor how to
    cure it the like by report of the oldest men in
    the countrey never happened before, time out of
    mind.
  • 1663, New England colonist "it pleased God to
    visite these Indeans with a great sickness, and
    such a mortalitie that, of 1000, above 900 and a
    halfe of them dyed, and many of them did rott
    above ground for want of buriall."

31
  • Impacts of disease
  • 1. Aztec leaders overwhelmed by 1) confusion of
    Quetzalcoatl myth, 2) treason of tributaries,
    and 3) massive deaths from disease
  • 2. War on the Beaver historian Calvin Martin
    argues near-extinction beaver Great Lakes result
    rejection of taboos as inexplicable disease,
    conversion, and loss of elders undermined Micmac
    society? kill beavers as enemy bringing on
    devastation
  • 3. Expansion of Indian wars some tribes largely
    unaffected? prey on weaker? need for new
    alliances (e.g. Iroquois Algonquians or
    Powhaten or Squanto)

32
Important Note about Biological Warfare
  • Because this devastation was unintentional (they
    wanted slaves and converts), the term genocide
    does not technically apply, even though the
    results were essentially the same
  • Upwards of 90 of all Native Americans pre-1492
    killed by Europeans (upwards of tens of millions
    of people)

33
III. Ecological Imperialism
  • Q How did a small number of Spaniards hold on to
    their conquest?
  • A With a little help from their friends

34
  • A. Weeds
  • Any plant that spreads rapidly and out-competes
    others on disturbed soil.
  • Native plant life had no resistance to the
    plantsespecially weedsthat the Europeans
    introduced to the New World.
  • Example Kentucky bluegrass, introduced by
    English around 1685? now covers entire SE

35
  • Whats the problem with weeds?
  • Weeds replace native plants? less food for native
    animals (toxins)? less food for Indians?
    starvation and further Indian population decline
    (vicious cycle)
  • (20th Century San Joaquin Valley introduced
    plants 63 of grasslands, 66 of woodland, 54 of
    chaparral)
  • C3 vs. C4 plants

36
  • B. Animals
  • Europeans brought barnyard animals with them to
    the New World horses, sheep, goats, domesticated
    dogs, chickens, cows, and pigs
  • Europeans let animals forage free for food?
    compete w/native animals (Indians severely
    punished for harming) tear up the soil? more
    weeds (see above vicious cycle)

37
C. Shock Troops
  • Animals, weeds, and disease traveled ahead of
    Europeans clearing the way Europeans often
    discovered empty lands because Indians had
    died/moved away
  • Europeans (esp. English) used emptiness to
    justify further conquest Indians didnt use the
    land, so why should they have it?
  • False assumption about the wilderness

38
D. Keystone Species
  • Indians manipulated environment (fire) in ways
    necessary for them to thrive? Americas more a
    garden than wilderness
  • Weakening of Indians? further disruption of
    eco-system? vicious cycle

39
Conclusion
  • Europeans were able to conquer the New World and
    maintain control over it in large part because of
    certain environmental advantagesdisease
    immunity, opportunistic plants and animalsthat
    increased the limited cultural and technological
    advantages that the Europeans brought with them.
