The economy, social structure and political orientation of the Byzantine
state were all transformed through the crises of the fourteenth century.
The decision to recover Constantinople in 1261 led, on the one hand, to
a chimeric dream of reconstituting the old empire, thus negating the reality
that, since the late twelfth century, the strongest forces in that area
favoured decentralisation, which would have led to smaller, more homogeneous
political entities with, perhaps, strong economic and cultural links
with each other. The recapture of Constantinople led to another important
choice: the orientation toward western Europe which Michael VIII followed
almost single-mindedly. This choice, however, could not be retained
at the political level. At the economic level, the Byzantine economy of
exchange and manufacturing became inextricably connected with the Italian
economy. Close cultural contacts with Italy also existed. Internally, there
were, in the course of the century, profound changes in the structure of the
dominant classes, of the cities, the merchant class. Many of these developments
were advantageous to new social groups and new structures just as
they harmed old ones; the great civil war resulted from such conflicts, but
failed to resolve them. The most serious problem of the Byzantine empire
in this period was that its internal development was thwarted and shaped
under intense pressure from foreign and hostile powers, the Serbs for a
short while, and the Ottomans. As a result, no viable units could coalesce
from the process of decentralisation, for surely individual cities, even with
their hinterland, were not viable units. The despotate of the Morea was an
exception, but its fate followed inexorably that of the rest of the empire
and indeed of the Balkans, which eventually were reunited under a new
imperial power, the Ottoman state.
