In Gradenigo’s reign we note the first indication of a policy of territorial aggrandisement on the Italian mainland. Little wars had already been waged: with the Paduans in 1142, to prevent the diversion of the course of the Brenta; and with Ferrara in 1240, to maintain trading privileges. In 1308 these were again endangered by a dispute between rival claimants for the lordship of Ferrara. Venice intervened and was brought into conflict with the Pope. His Holiness, as a temporal enemy, fought at a vantage, for to the material bolts of Mars he was able to add the spiritual thunders of the Church. When the Papal warning was received, the Doge addressed the Councillors, and stoutly defended his policy and told them that they were not children to be frightened by words. There was an angry scene in the council chamber, and for once the ominous cries, “Guelph and Ghibelline,” were heard within the walls of the palace. The ducal party maintained their position and the ban was laid on Venice. The Doge, his Councillors and the citizens were excommunicated, their possessions in Ferrara confiscated, every treaty with them declared void, commercial relations forbidden, and all the clergy summoned to leave. The Pope’s words, however, were winged with terror to the Venetians. News soon came of banks, factories and ships sacked in Italy, France and England, and even in far Asia. Their trade, except with the infidel, was paralysed; religious and civic life disintegrated. But the Republic never winced. On the very day that the papal interdict reached Venice instructions were sent to the Venetian _podestà_ at Ferrara to fortify himself in _Castel Tebaldo_ and manfully and potently to uphold the rights and honour of his country. The Venetian garrison, however, weakened by disease, surrendered after a long struggle, and met the fate of the vanquished. The fleet was destroyed, and growing unrest in the State forced the Doge and his party to make terms with the Pope. Ferrara was acknowledged to be a papal fief, and an indemnity paid for the restoration of the trading privileges of the Republic.
