CASTRUCCIO CASTRACANI DEGLI ANTELMI NELLI (1281-1328), duke of Lucca, born March 29, 1281, at Castruccio, near Lucca, was a noted condottiere and Ghibelline. He served under Philip IV. of France in Flanders, then with the Visconti in Lombardy, and in 1313 with Uguccione della Fag giuola, lord of Pisa, in central Italy. In 1316 he was elected lord of Lucca, and spent many years in incessant warfare against the Florentines, whom he defeated at Altopascio in 1325, the year in which he was created duke of Lucca, Pistoja, Volterra and Luni by the emperor Louis the Bavarian. In 1327 he captured Pisa, of which he was made imperial vicar. He died Sept. 3, 1328.
