Acciaiolo Acciaiuoli

Acciaiolo Acciaiuoli (died 1349) was a Florentine banker and politician of the Acciaiuoli family, the illegitimate son of Niccolò Acciaiuoli il Vecchio and father of Niccolò Acciaiuoli, the future grand seneschal of Naples. He took the family bank south, founding branches at Naples and in Greece, the Levant and Barbary; the Naples branch proved especially important to the family's fortune.

He lent large sums to King Robert of Naples, who named him chamberlain and counsellor in 1333, and from 1335 until his death he was the Angevin king's perpetual vicar at Prato.

In Florence he was twice prior of liberty, served among the war magistrates in 1336, and commanded the fortress of Pistoia in 1339. He died in Florence in 1349.
