Bentivoglio was an Italian family that became the de facto rulers of Bologna and responsible for giving the city its political autonomy during the Renaissance, although their rule did not survive a century.
History
The presence in Bologna of the Bentivoglio family is first recorded in 1323. Originally from the castle of that name in the neighborhood of Bologna, the family claimed descent from Enzio, King of Sardinia, an illegitimate son of Frederick II, Holy Roman Emperor. During the fourteenth century, the family, belonging to one of the worker's guilds at Bologna, had gained power as pro-papist Guelph leaders in the fourteenth century. Amid the faction-conflicts of the commune, on 14 March 1401, Giovanni I Bentivoglio, with the help of Gian Galeazzo Visconti, declared himself signore and Gonfaloniere di Giustizia. The Visconti however soured on Giovanni, and he was defeated and killed on 26 June 1402 at the Battle of Casalecchio and was interred in the church of San Giacomo Maggiore. During the next few decades, the city's political status -and the family's fortunes- remained unpredictable. The son of Giovanni I, Anton Galeazzo, was a lecturer in civil law who briefly assumed power in Bologna in 1420, but was quickly overthrown. He became a condottiero, and was assassinated by papal officials on 23 December 1435 due to fears over his growing power. During his reign the Bentivoglio received the fief of Castel Bolognese. In 1438 Annibale I, a putative son of Anton Galeazzo , led a city revolt against the Papacy. He tried to make peace with the Visconti of Milan and to convince the Pope not to place Bologna under papal dominion. In 1442, the Visconti condottiere Niccolò Piccinino imprisoned Annibale and his supporters at Varano, but Annibale was freed by Galeazzo Marescotti in 1442. When Annibale returned to Bologna, the powers of government were conferred to him, a sign that the city recognized the family's political importance. However, on 24 June 1445, with the support of Pope Eugene IV, Battista Canneschi, succeeded in assassinating his rival Annibale. Annibale was succeeded by Sante I. Sante was also of dubious paternity and origin, but alleged to be a son of Ercole Bentivoglio, a cousin of Annibale I. Originally an apprentice of the wool guild of Florence, Sante ruled as signore of Bologna from 1442. Sponsored by Cosimo de' Medici, Sante Bentivoglio ushered in a brief period of political tranquility. Always technically under papal sovereignty, the city obtained some actual autonomy and recreated a regime of the feudal type, with a communal senate composed of the landowning nobility, the new rich, and the papal nobility. Bologna also strengthened its relations with Venice, Milan, and Florence. Sante was succeeded by Giovanni II, the son of Annibale I, who ruled as virtual tyrant of Bologna. In 1506, the noble Bentivoglio family was brought to ruin by Pope Julius II when he expelled Giovanni II from Bologna. A son of Giovanni II, Annibale II, married Lucrezia d'Este, an illegitimate daughter of Duke Ercole I of Ferrara, in 1487. He served as a condottiero. During a rebellion in 1511 against Julius II, Annibale II with the help of the French took control o Bologna, but he was able to rule for only a year. He was hated by other rival families, such as the Ghislieri and the Canetoli, and was subsequently assassinated. Annibale II was the last ruler of his line. In exile, the Bentivoglio family established themselves in Ferrara and produced several notable prelates.
Ercole Bentivoglio, the putative father of Sante I who lived in exile in Florence and Ferrara, wrote a long poem on dietetic, greatly extolling the medical properties of cheese. He also wrote satirical works. The Bentivoglio Family, expelled from Bologna in 1506, established themselves in Ferrara, where they produced some important prelates, such as:
Cardinal Guido Bentivoglio, though a disciple of Galileo, was one of the Inquisitors-General who signed his condemnation. Papal diplomat and historian of the Flanders War in his work Della Guerra di Fiandra.
The third son of Giovanni II, Alessandro Bentivoglio, who had married Ippolita Sforza, became a counselor of the last duke of Milan and later governor of the town, giving origin to a lombard branch of the family. A notable recent member of the family is Galeazzo Benti, originally Galeazzo Bentivoglio, 20th century actor.
Power base
The Church of San Giacomo Maggiore, originally built in the mid-13th century, was adopted in the 15th century by the Bentivoglio family as the center of their power base in the surrounding neighborhood, and they embellished the church accordingly. It included the tomb of Anton Galeazzo Bentivoglio by Jacopo della Quercia and the Bentivoglio family's own private chapel, the altar of which has some striking artwork by Lorenzo Costa depicting family victories over other Bolognese dynasties.
