culture and Orthodox Christianity. The main exceptions were, first, in the
Balkan interior, where Slavonic, Vlakh and Albanian speakers predominated,
along with a sizeable, non-integrated Armenian population, and, secondly, in
the areas of southern Italy and Asia Minor which had been lost to the empire in
the late eleventh century, and in which Greek-speaking Orthodox Christians
were numerous. Looked at another way, Byzantium, or ‘Romania’, as its inhab-
itants referred to it, corresponded to the area needed to support a large standing
army and navy, an expensive international diplomacy and an enormous cap-
ital city. There was an outer frontier zone, broad in the Balkans, thin in Asia
Minor, which was partly protective shield and partly forward base for imperial
operations in Italy and Syria. In this zone, direct imperial administration was
limited to a few key strongholds, and local resources were either unexploited
(to starve invading forces), untaxed (to secure local loyalties) or used to pay for
regional defence and diplomacy (notably the case in Cyprus). Surrounded by
this zone, in an area consisting essentially of the Aegean and southern Black
Sea hinterland, the core Comnenian empire existed largely to maintain the
safety, the opulence and the population of Constantinople.
The pull of Constantinople was due not only to its role as the adminis-
trative capital, but also to its status as the ‘reigning city’ of New Rome, an
unrivalled showcase of holy relics, glittering treasures, ancient public monu-
ments and magnificent buildings, a megalopolis with a population somewhere
between 200,000 and 400,000 which appears to have been growing steadily
throughout the eleventh and twelfth centuries, even as the empire contracted
overall in territorial extent. By the late twelfth century, the relationship be-
tween the ‘reigning city’ and the provinces was seen, on both sides, as that
of a metropolis to its satellite tributaries, which were inhabited by culturally
inferior second-class citizens. Ownership of the empire’s prime agricultural
land was overwhelmingly concentrated in Constantinople. In the ‘outer ter-
ritories’, as opposed to Constantinople, heretics abounded, ignorance of the
law was standard, uncanonical, semi-pagan religious customs were practised,
people spoke bad Greek and there was no protection against corrupt and brutal
officials. Yet this unequal relationship obviously depended on the productiv-
ity of the suppliers, on the ability of provincial communities to provide the
metropolis not only with money, foodstuffs, manpower and raw materials,
but also, increasingly, with manufactured goods, such as silks from Thebes
and knives from Thessalonica. It is abundantly clear that Constantinople was
not the only place where urban society was expanding. It is also clear, al-
though documentation is patchy, that revenue could not have been raised or
military defence organized in the localities without the cooperation and partic-
ipation of the local aristocracy, the archontes. In frontier cities, such as Durazzo,
Philadelphia or Trebizond, their loyalty was crucial in keeping invaders out.
