was continually kept aflame by the greed of the nobles, who hoped to convert the conflict into a ladder to power, and whose own ambitions were spurred by the crafty encouragement of Florence. Corsica was ruled by a certain Sinucello, bearing the title of Judge of Cinarca. He had been educated in Pisa, and the Republic had assisted him to regain and increase his hereditary possessions in the island. Governing there as a vassal of Pisa, he nevertheless transferred his allegiance to the Genoese, who occupied another part of the island. Later on, after perpetrating every species of cruel and tyrannous deeds, he turned against the Genoese and devastated their Corsican towns. Taking refuge at Pisa, that republic granted him protection as a former vassal, equally regardless of the subsequent treaties, by which he had sworn fealty to Genoa, and of all the barbarities he had committed. Pisa tried to reinstate Sinucello in Corsica by force, but as the Genoese were determined to keep him at a distance, this served to provoke hostilities. In fact, being sent back to the island with 120 horse and 200 foot, he was able to recapture his possessions; but from that moment (1282) the Genoese and Pisan ships were always chasing one another over the Mediterranean in order to engage. Accordingly, from the end of 1282 to the August of 1283, a continual series of sanguinary conflicts took place, sometimes attaining the proportions of real naval battles; and although the Pisans were generally defeated, they always rallied their forces, and prepared to resume the struggle. On one occasion half their fleet perished in a storm; nevertheless, shortly after this (1284) they sent twenty-four galleys to escort Count Fazio to Sardinia, where collisions with the Genoese were of constant occurrence. In fact, on the 1st of May, they encountered the latter's fleet, gave battle, and carried on an obstinate fight that lasted the whole day. Finally, however, the Pisans were beaten off, leaving thirteen galleys and a great number of prisoners in the enemy's hands. Notwithstanding this reverse, the same year witnessed another naval battle between the two republics, that proved one of the most memorable fights on record in the Middle Ages.
