It has been contended by those who would celebrate Columbus that
accusations concerning his perpetration of genocide are distortive
"revisions" of history. Whatever the process unleashed by his
"discovery" of the "New World," it is said, the discoverer
himself cannot be blamed. Whatever his defects and offenses, they are
surpassed by the luster of his achievements; however "tragic" or
"unfortunate" certain dimensions of his legacy may be, they are
more than offset by the benefits even for the victims of the resulting
blossoming of a "superior civilization" in the
Americas. Essentially the same arguments might be advanced with regard
to Adolf Hitler: Hitler caused the Volkswagen to be created, after
all, and the autobahn. His leadership of Germany led to jet
propulsion, significant advances in rocket telemetry, laid the
foundation for genetic engineering. Why not celebrate his bona fide
accomplishments on behalf of humanity rather than "dwelling" so
persistently on the genocidal by-products of his policies?
To be fair, Columbus was never a head of state. Comparisons of
him to Nazi SS leader Heinrich Himmler, rather than Hitler, are
therefore more accurate and appropriate. It is time to delve into the
substance of the defendants' assertion that Columbus and Himmler, Nazi
Lebensraumpolitik (conquest of "living space" in eastern Europe) and
the "settlement of the New World" bear more than casual
resemblance to one another. This has nothing to do with the Columbian
"discovery," not that this in itself is completely
irrelevant. Columbus did not sally forth upon the Atlantic for reasons
of "neutral science" or altruism. He went, as his own diaries,
reports, and letters make clear, fully expecting to encounter wealth
belonging to others. It was his stated purpose to seize this wealth,
by whatever means necessary and available, in order to enrich both his
sponsors and himself. Plainly, he pre-figured, both in design and by
intent, what came next. To this extent, he not only symbolizes the
process of conquest and genocide which eventually consumed the
indigenous peoples of America, but bears the personal responsibility
of having participated in it. Still, if this were all there was to it,
the defendants would be inclined to dismiss him as a mere thug along
the lines of Al Capone rather than viewing him as a counterpart to
Himmler.
The 1492 "voyage of discovery" is, however, hardly all that is
at issue. In 1493 Columbus returned with an invasion force of
seventeen ships, appointed at his own request by the Spanish Crown to
install himself as "viceroy and governor of [the Caribbean islands]
and the mainland" of America, a position he held until
1500. Setting up shop on the large island he called Espa–ola (today
Haiti and the Dominican Republic), he promptly instituted policies of
slavery (encomiendo) and systematic extermination against the native
Taino population. Columbus's programs reduced Taino numbers from as
many as eight million at the outset of his regime to about three
million in 1496. Perhaps 100,000 were left by the time of the
governor's departure. His policies, however, remained, with the
result that by 1514 the Spanish census of the island showed barely
22,000 Indians remaining alive. In 1542, only two hundred were
recorded. Thereafter, they were considered extinct, as were Indians
throughout the Caribbean Basin, an aggregate population which totaled
more than fifteen million at the point of first contact with the
Admiral of the Ocean Sea, as Columbus was known.
