Nicolò Acciaioli (cardinal)

Nicolò Acciaioli or Niccolò Acciaiuoli (Florence, 6 July 1630 – Rome, 25 February 1719), was an Italian Cardinal. He was Dean of the Sacred College between 1715 and 1719.

He belonged to the noble Florentine Acciaioli family, third of the ten children of Senator Ottaviano Acciaioli and Maria Acciaioli and was the uncle of Cardinal Filippo Acciaioli (1700 – 1766).

He graduated in law in Rome. In 1657 he became Auditor camerae at the Apostolic Camera. In the consistory of 29 November 1669 he was appointed Cardinal by Pope Clement IX despite not having yet received his minor orders. Only in March of the following year, he received the title of Cardinal-deacon assigned to the deaconry of Santi Cosma e Damiano. He was Papal legate to the city of Ferrara on several occasions for several years.

In 1689 he became Cardinal protodeacon and in October of the same year he opted for the deaconry of Santa Maria in Via Lata, but already one month later he became Cardinal priest of San Callisto. In 1690 he was appointed Abbot commendatory of the abbey of Sant'Angelo de Frigillo in Mesoraca, Calabria. Three years later he became Cardinal bishop of Frascati, receiving episcopal consecration on 8 November 1693. In 1700 he opted for the Suburbicarian Diocese of Porto–Santa Rufina.

He became Dean of the Sacred College in 1715 and had the title of Cardinal bishop of the Suburbicarian sees of Ostia and Velletri, also assuming the office of Governor of Velletri.
In 1717 he became secretary of the Congregation of the Sacred Roman and Universal Inquisition, a position he held until his death.

His body is buried in the church of San Lorenzo, near the Florence Charterhouse, built by a member of his family in the 14th century.
