He returned to Rome on 3 February 1482. Shortly thereafter the sum of 300,000 ecus of gold was received from the French in a subsidy of the war. On 31 January 1483 Cardinal della Rovere was promoted suburbicarian Bishop of Ostia, in succession to Cardinal Guillaume d'Estouteville who had died on 22 January. It was the privilege of the Bishop of Ostia to consecrate an elected pope a bishop, if he were not already a bishop. This actually occurred in the case of Pius III (Francesco Todeschini-Piccolomini), who was ordained a priest on 30 September 1503 and consecrated a bishop on 1 October 1503 by Cardinal Giuliano della Rovere. Around this time, in 1483, an illegitimate daughter was born, Felice della Rovere. On 3 November 1483, Cardinal della Rovere was named Bishop of Bologna and Papal Legate, succeeding Cardinal Francesco Gonzaga, who had died on 21 October. He held the diocese until 1502. On 28 December 1484, Giuliano participated in the investiture of his brother Giovanni as Captain-General of the Papal Armies by Pope Innocent VIII. By 1484 Giuliano was living in the new palazzo which he had constructed next to the Basilica of the Twelve Apostles, which he had also restored. Pope Sixtus IV paid a formal visit to the newly restored building on 1 May 1482, and it may be that Giuliano was already in residence then. War with Naples Sixtus IV died on 12 August 1484 and was succeeded by Innocent VIII. After the ceremonies of the election of Pope Innocent were completed, the cardinals were dismissed to their own homes, but Cardinal della Rovere accompanied the new Pope to the Vatican Palace and was the only one to remain with him. Ludwig Pastor quotes the Florentine ambassador as remarking, "[Pope Innocent] gives the impression of a man who is guided rather by the advice of others than by his own lights." The ambassador of Ferrara stated, "While with his uncle [Della Rovere] had not the slightest influence, he now obtains whatever he likes from the new Pope." Della Rovere was one of the five cardinals named to the committee to make the arrangements for the Coronation. In 1485 Pope Innocent and Cardinal della Rovere (as the Pope's new principal advisor) decided to involve themselves in the political affairs of the Kingdom of Naples, in what was called the Conspiracy of the Barons.
