Gambacorta
The Gambacorta or Gambacorti were a merchant noble family of Pisa, traced to the thirteenth-century trader Buonaccorso, called Coscio, who moved from the Pisan countryside into the city and built a fortune trading with Naples and Sardinia. They led the Bergolini faction, which favoured alliance with Florence.
Andrea Gambacorta became head of the Pisan government after the Bergolini victory of 1347. His nephew Francesco succeeded him in 1354 but was deposed and killed in 1355. Pietro Gambacorta brought the family back to power in 1369, but in 1392 Jacopo d'Appiano's conspiracy drove them out and Pietro was executed with his sons.
After Florence conquered Pisa in 1406 the Gambacorta held Bagno di Romagna until 1453, when Gherardo moved the family to Naples and entered the Neapolitan patriciate. That branch died out in 1703. Chiara Gambacorti, a Dominican, was beatified in 1830.
