The Urban Way of Life

tensive the area under the control of any one town was. The central gov-
ernments were relatively strong and were able to ensure that the market
area of each was as extensive as was necessary to maintain a regular sup-
ply of foodstuffs and other commodities. Their “city limits” were effec-
tively of little or no importance. In central Europe, where, in the absence
of a strong central authority, there could have been a deep hostility be-
tween a town and its surrounding territories, the possession of a large
contado was highly desirable. Augsburg, for example, had to maintain
good relations with the lords of surrounding lands. It might otherwise
have quite literally been starved into surrender.
Every town was the focal point of a region, as it had been since urban
history began. The extent of this region was a function of the city’s size
and the range of its economic activities. It would also have been influ-
enced by the terrain, by transportation facilities, and by obstacles to
movement such as mountains and rivers. It would also have been affected
by political considerations: relations with surrounding territories and
treaty privileges and obligations. But let us assume that the area in ques-
tion was homogeneous, that the quality of the land and ease of move-
ment over it did not vary in any direction. No area on this earth could
have satisfied these conditions. Perhaps the nearest approach would have
been the plains of eastern England and of northern France. In these areas
every small town, which, by definition, was unable to supply its own needs
in foodstuffs and at the same time required a market for its own products,
was surrounded by its market region. The extent of this market region
would have been determined primarily by the distance peasant farmers
were prepared to travel to their nearest urban market. The medieval Eng-
lish jurist, Bracton (d. 1268), enunciated a simple rule. A man could walk
twenty miles in a day (at least, he was able to do so then). He would be
required to spend at least a third of a day at the market, thus leaving him
with two-thirds of the day for his outward and homeward journeys. Dur-
ing this period he could cover at most two-thirds of the twenty miles that
made up the hypothetical day’s journey. He would thus have to live not
more than six and two-thirds miles from a market. Our hypothetical, ho-
mogenous land would thus be divided up into market areas, all of them
of the same size and within each of which the peasant was guaranteed
access to a market within the limits just described. Since, however, the
land surface cannot be divided into circular areas without their overlap-
ping, it is assumed that they must be hexagonal, as in Figure 16.
