Bentivoglio, Cornelio an Italian prelate, was born at Ferrara in 1668. Pope Clement XI made him chaplain, afterwards titular archbishop of Carthage, and legate at the French court. His zeal against the Jansenists gained for him the favor of Louis XIV, but when the latter died he was recalled. In 1719 he was made cardinal, and in 1720 legatus a latere for Ravenna and the Romagna.
Under Benedict XIII he was appointed by the king of Spain, in 1726, as his representative at the papal curia. He died in 1732. See Kaulen, in Wetzer u. Welte's Kirchenlexikon, s.v. (B.P.)
