Acciaioli a name common to three cardinals, viz.:
1. ANGELOS, born in 1340 at Florence, and died at Pisa in 1407. He was known for his learning, experience, and integrity. In 1883 he was made archbishop of Florence, and in 1385 cardinal by pope Urban VI. He resisted all endeavors to bring him on the side of the antipope Clement VII, and defended in words and deeds the regularity of the election of pope Urban VI. After the death of this pope, half of the votes were given in the conclave in favor of Acciaioli; but, to end the schism, he directed the election towards Boniface IX. The new pope made him cardinal-bishop of Ostia, and sent him to Germany, Slavonia, and Bulgaria to settle pending difficulties. He afterwards became governor of Naples and guardian of the young king Ladislaus, whom he brought to Naples, and accompanied, some time after, on his march to Hungary; reconciled, after his return, the pope with Orsini; and reformed the Monastery of St. Paul, at Rome. He died on his way to Pisa, and was buried at Florence. See Eggs, Purp. Docta, 2, 88.
2. NICCOLO, born at Florence, and died at Rome, Feb. 23, 1719, as cardinal-bishop of Ostia.
3. FILIPPO, who belonged to the same family, was born at Rome, March 12,1700. He was nuncio at Portugal, but, on account of his interference in behalf of the Jesuits, he was sent away by Pombal with military force. Clement XIII made him cardinal in 1759 and he died at Ancona, July 4, 1766. See-Wetzer u. Welte, kirchen-Lex. s.v. (B. P.)
