Lecture 37: The Americas in the Later Agrarian Era


The Americas in the Later Agrarian Era..........................................


LECTURE


Market relations and warfare seem to have linked all these areas of
evolving Agrarian civilization into a large network of exchanges and
warfare. So, it may be appropriate to talk of an evolving Mesoamerican
“world system.”

H


ow similar was the evolution of Agrarian civilizations in the
American and Afro-Eurasian world zones? And what were the
crucial differences? In the Americas, Agrarian civilizations evolved
in Mesoamerica and the Andes. In both regions, evidence of embryonic
Agrarian civilizations began to appear from the 2nd millennium B.C.E. In
Mesoamerica, incipient Agrarian civilizations appeared in the middle of the
2 nd millennium B.C.E. They appear among the Olmec of Southeast Mexico,
near modern Veracruz, on the Gulf of Mexico. Improved varieties of maize,
beans, and squash allowed rapid population growth in regions of heavy
rainfall, where drainage was more important than irrigation. Towns such as
Lorenzo (with a population of about 2,500 people) and La Venta appeared.
They had large ceremonial centers, with pyramid-like tombs up to 33 meters
high. The Olmec made huge and distinctive basalt stone heads. With no large
domestic animals, these had to be transported by humans, presumably under
compulsion. The small size of these towns suggests that they represented
polities perhaps at the level of chiefdoms. The presence of obsidian and other
precious goods at Olmec sites shows the existence of extensive exchange
networks. La Venta was destroyed violently in about 400 B.C.E., clear
evidence of the importance of warfare. An inscribed stone found in 2006 in
Veracruz suggests that the Olmec had already developed a writing system,
though it has not yet been deciphered.

After 1000 B.C.E., larger communities evolved in the Oaxaca valley of
South Mexico, with evidence of craft specialization, canal building, markets,
and writing. By 500 B.C.E., there existed a cluster of city-states, reminiscent
of 3rd-millennium Sumer. By 500 C.E., the region’s largest settlement, Monte
Alban, may have had 20,000 or more inhabitants; it is often thought of as
the ¿ rst large city of the Americas. Carved stone engravings found nearby
