A cardinal (Cardinal of the Holy Roman Church) is a senior ecclesiastical leader, considered a Prince of the Church, and an ordained bishop of the Roman Catholic Church. The cardinals of the Church are collectively known as the College of Cardinals. The duties of the cardinals include attending the meetings of the College and making themselves available individually or in groups to the Pope as requested. Most have additional duties, such as leading a diocese or archdiocese or managing a department of the Roman Curia. A cardinal's primary duty is electing the bishop of Rome when the see becomes vacant. During the sede vacante, the day-to-day governance of the Holy See is in the hands of the College of Cardinals. The right to enter the conclave of cardinals where the pope is elected is limited to those who have not reached the age of 80 years by the day the vacancy occurs.
In 1059, the right of electing the pope was reserved to the principal clergy of Rome and the bishops of the seven suburbicarian sees.
In Rome the first persons to be called cardinals were the deacons of the seven regions of the city at the beginning of the 6th century, when the word began to mean "principal," "eminent," or "superior."
By decree of a synod of 769, only a cardinal was eligible to become bishop of Rome. Cardinals were granted the privilege of wearing the red hat by Pope Innocent IV in 1244.
