Pisa

(anc. Pisæ ). One of the oldest and most beautiful cities of Italy, and, till lately, the capital of the now extinct grand duchy of Tuscany, on the banks of the river Arno. Pisæ was one of the twelve cities of Etruria; it is frequently mentioned in the Ligurian wars as the headquarters of the Roman legions. Early in the 11th century, Pisa had risen to the rank of a powerful republic. Its troops took part in all the great events of the Holy Land; and its fleet in turn gave aid to the pope in Southern Italy, to the emperor in Northern France, chastised the Moors, and exacted its own terms from the Eastern emperors. In their wars with the Saracens of Sardinia, the Pisans had conquered Sardinia, Corsica, and the Balearic Islands, and for a time maintained their ground against their hereditary enemies, the Genoese; but having sided with the Ghi bel lines in the long wars which desolated the empire, Pisa suffered severely at the hands of the victorious Guelphic party. Indeed, the rivalry of the Guelphic cities of Florence, Lucca, and Siena nearly brought Pisa to the brink of ruin at the close of the 13th century; and after struggling for more than a hundred years against external foes and the internal di ensions between the democratic mob and the Ghibelline nobles, without losing their character for indomitable valor, the Pisans finally threw themselves under the protection of Galeazzo Visconti of Milan. It became subject to Florence after a long siege, 1405-6. In 1494, Pisa became independent under the protection of Charles VIII. of France. When the French left Italy, the old struggle was renewed; and after offering a desperate resistance, the Pisans, in 1509, were compelled by hunger to surrender the city to the Florentine army besieging the walls.
