Lecture 29: From Villages to Cities


From Villages to Cities ....................................................................


LECTURE


The appearance of Agrarian civilizations, from about 5,000 years ago,
marks an important subordinate threshold in this course.

W


ith Agrarian civilizations we get, for the ¿ rst time, cities, states,
and ... writing! This means that for the ¿ rst time we have written
evidence, precise dates, and even some names. In short, we enter
the realm of what many historians might regard as “real history.” Suddenly,
we have a mass of information and ideas. This creates new problems.
Whereas in discussing biology or geology there was a broad consensus about
the main ideas, historians debate endlessly about the main lines of historical
development, so there is more room for controversy here than in any earlier
part of this course. From now on, our main challenge will be to avoid getting
too caught up in the details or the controversies of historians and try to keep
our eye on the overall shape of human historical development.

Lectures Twenty-Nine through Thirty-Seven survey the 5,000 years or so
during which “Agrarian civilizations” dominated the history of most people
on Earth. This is the largest single group of lectures in this course. This
lecture de¿ nes Agrarian civilizations and offers a brief chronology of their
initial appearance. Then we turn to Mesopotamia, located in modern Iraq, to
describe how increasing productivity created the foundations for some of the
earliest Agrarian civilizations.

The term “civilization” can be used in many different ways, so I need to
explain that I use it neutrally, as a label for a particular type of human
community. I do not use it to imply any value judgments about these
communities. However, I will argue that Agrarian civilizations were
more complex than all earlier human societies. Agrarian civilizations had
distinctive characteristics.

x They had large, networked communities of many millions
of people.
