VI. THE JEALOUSIES AND NAVAL WARS OF VENICE AND GENOA. LAMBA DORIA'S
EXPEDITION TO THE ADRIATIC; BATTLE OF CURZOLA; AND IMPRISONMENT OF MARCO
POLO BY THE GENOESE.
[Sidenote: Growing jealousies and outbreaks between the Republics.]
31. Jealousies, too characteristic of the Italian communities, were, in
the case of the three great trading republics of Venice, Genoa, and Pisa,
aggravated by commercial rivalries, whilst, between the two first of those
states, and also between the two last, the bitterness of such feelings had
been augmenting during the whole course of the 13th century.[1]
The brilliant part played by Venice in the conquest of Constantinople
(1204), and the preponderance she thus acquired on the Greek shores,
stimulated her arrogance and the resentment of her rivals. The three
states no longer stood on a level as bidders for the shifting favour of
the Emperor of the East. By treaty, not only was Venice established as the
most important ally of the empire and as mistress of a large fraction of
its territory, but all members of nations at war with her were prohibited
from entering its limits. Though the Genoese colonies continued to exist,
they stood at a great disadvantage, where their rivals were so predominant
and enjoyed exemption from duties, to which the Genoese remained subject.
Hence jealousies and resentments reached a climax in the Levantine
settlements, and this colonial exacerbation reacted on the mother States.
A dispute which broke out at Acre in 1255 came to a head in a war which
lasted for years, and was felt all over Syria.
