Acciaioli

The Acciaioli were a Florentine family whose bank operated from Greece to western Europe. In 1331 Niccolò Acciaioli went to Naples to manage its interests and gained influence at court.

The bank collapsed in 1345, but Niccolò helped Louis of Taranto reconquer Achaea and was appointed lord of Corinth in 1358. Another branch ruled the Duchy of Athens from about 1390 to 1460. Before 1512 Simone di Zanobi Acciaioli moved to Madeira to represent the family's commercial interests, founding a Portuguese line.
