Rinaldo d'Este

Rinaldo d'Este (1618 – 30 September 1672) was an Italian Catholic cardinal.

Early life and education Rinaldo d'Este was born in 1618, the son of Alfonso III d'Este, Duke of Modena, and Isabella of Savoy. He was the brother of Francesco d'Este who succeeded his father as Duke of Modena. As a boy, he undertook military study in Modena but left to answer an ecclesiastic calling.

Early ecclesiastic career Little is known of his early Church career but he was elevated to cardinal by Pope Urban VIII at the request of Ferdinand III, Holy Roman Emperor, in 1641; and this was published in the consistory of 16 December that year. However, the First War of Castro broke out between Barberini Pope Urban and the Farnese Dukes of Parma. As a result, Rinaldo d'Este refused to travel to Rome to receive his cardinal's hat. Instead, when Pope Urban died in 1644, he travelled to Rome to participate in the papal conclave which elected Pope Innocent X who then conducted the ceremony following his own papal coronation.

After Pope Innocent's election, though, d'Este had a falling out with members of the Spanish faction of the College of Cardinals who had been the driving force behind the Pope's election against candidates put forward by the French faction. After the falling out, d'Este declared himself for France. As a result, though his family had previously been in conflict with the Barberini, he became their ardent supporters while they were in exile in France.
