The two parties of the Guelfs and Ghibellines, since the death of Henry VII, no longer nearly balanced each other in virtue, talents, and patriotism. In the beginning of their struggle, there were almost as many republics on one side as the other; and sentiments as pure and a devotion as generous equally animated the partisans of the empire and of the church. But, in the fourteenth century, the faction of the Ghibellines had become that of tyranny--of the Guelfs that of liberty. The former displayed those great military and political talents which personal ambition usually develops. In the second were to be found, almost exclusively, patriotism, and the heroism which sacrifices to it every personal interest. The republic of Pisa alone, in Italy, united the love of liberty with the sentiments of the Ghibelline party. This republic had been thunderstruck by the death of Henry VII at a moment when a career of glory and prosperity seemed to open on him. Pisa, exhausted by the prodigious efforts which she had made to serve him, was true to herself, when all the Guelfs of Tuscany rose at once, on the death of Henry, to avenge on her the terror which that monarch had inspired. She gave the command of her militia to Uguccione dà Faggiuola, a noble of the mountainous part of Romagna, which, with the March, produced the best soldiers in Italy. The Pisans, under the command of Faggiuola, obtained two signal advantages over the Guelfs. They took Lucca, on the 14th of June, 1314, while the Lucchese Guelfs and Ghibellines were engaged in battle in the streets of that city; and, on the 29th of August of the same year, they defeated, at Montecatini, the Florentines, commanded by two princes of the house of Naples, and seconded by all the Guelfs of Tuscany and Romagna. But the Pisans soon perceived that they were fighting, not for themselves, but for the captain whom they had chosen. Almost immediately after his victory, he began to exercise an insupportable tyranny over Pisa and Lucca. Fearing much more the citizens of these republics than the enemies of the states, he, on the slightest suspicion, employed the utmost severity against all the most illustrious families. At Lucca, he threw into a dungeon Castruccio Castracani, the most distinguished of the Ghibelline nobles, who had recently returned to that city with a brilliant reputation, acquired in the wars of France and Lombardy. A simultaneous insurrection at Lucca and Pisa, on the 10th of April, 1316, delivered these cities from Uguccione dà Faggiuola and his son.[d]
