Historically, cardinals were the clergy of the city of Rome, serving the Bishop of Rome as the Pope, who had clerical duties in parishes of the city. The College has its origins in the events surrounding the crowning of Henry IV as King of Germany and Holy Roman Emperor at the age of six, after the unexpected death of Henry III in 1056. Until this moment secular authorities had significant influence over who was to be appointed Pope, and the Holy Roman Emperor in particular had the special ability to appoint him. This was significant as the aims and views of the Holy Roman Emperor and the Church did not always coincide. Members of what was to become known as the Gregorian Reform took advantage of the new King and his lack of power, and in 1059 declared that the election of the Pope was an affair only for the Church. This was part of a larger power struggle, which became known as the Investiture Controversy, as the Church attempted to gain more control over their clergy, and in doing so gain more influence in the lands and governments they were appointed to. Theological implications aside, its creation represented a significant shift in the balance of power in the Early Medieval world. From the beginning of the 12th century, the College of Cardinals started to meet as such, when the cardinal bishops, cardinal priests, and cardinal deacons ceased acting as separate groups.
The Dean of the College of Cardinals and the Sub-Dean are the president and vice-president of the college. Both are elected by and from the cardinals holding suburbicarian dioceses, but the election requires Papal confirmation. Except for presiding, the dean has no power of governance over the cardinals, instead acting as primus inter pares (first among equals).
The Church cites Acts 6 as the formation of the Sacred College of Cardinals. Specifically, the seven assistants, Stephen, Philip, Nicanor, Timon, Nicholas, Parmenas, and Prochorus, selected by the Apostles to relieve them of the more mundane tasks of the Church so that they might concentrate more on prayer, contemplation, and preaching. As early as the third century, these assistants were defined as critical supporters of the papacy, and by the fourth century, the title of Cardinal was applied to these consultors of the Pope.
The word cardinal itself is derived from the Latin Carda, translated as "hinge". The cardinals were believed to facilitate a relationship between the theological and governmental roles of the hierarchy of the Church as a sort of pivot; on them hung the relationship between Christ and His Church on Earth, headed by the pope. This definition of helper has not changed over the years, and popes have not ceased to depend on the College for advice on doctrine and government.
Towards the end of the 600s, the title of Cardinal had become synonymous with an honor, and was no longer reserved to men who served the pope as special assistants. Sts. Augustine and Ambrose applied the term to truths of life and Christian virtues respectively. In 845 the Council of Meaux "required Bishops to establish Cardinal titles or parishes in their towns and outlining districts." At the same time, the popes began referring to the cardinal priests of Rome to serves as legates and delegates within Rome at ceremonies, synods, councils, etc., as well as abroad on diplomatic missions and councils. Those who were assigned to the latter roles were given the titles of Legatus a latere (Cardinal Legate) and Missus Specialis (Special Missions).
During the pontificate of Stephen V (816-17), the three classes of the College that are present today began to form. Stephen decreed that all cardinal-bishops were bound to say Mass on rotation at the high altar at St. Peter's Basilica, one per Sunday. The first class to form was that of the cardinal-deacons, direct theological descendants of the original seven ordained in Acts 6, followed by the cardinal-priests, and finally, the cardinal-bishops.
The College played an integral part in various reforms within the Church as well, as early as the pontificate of Pope Leo X (1050). In 759, the third Lateran Council declared that only Cardinals could assume the papacy, a requirement that has since lapsed. In 1130, under Urban II, all the classes were permitted to take part in papal elections; up to this point, only cardinal-bishops had this role.
By the end of the 1300s, the practice of solely Italian cardinals had ceased. Between the 1300s and 1600s, there was much struggle for the College between the cardinals of the day and the reigning popes. The most effective way for a pope to increase his power was to increase the number of cardinals, promoting those who had nominated him. Those cardinals in power saw these actions as an attempt to weaken their influence. In 1517, Pope Leo X added another thirty-one cardinals, bringing the total to sixty-five so that he could have a supportive majority among the cardinalate. Paul IV brought the total to seventy. Pius IV raised an additional six. By the papacy of Sixtus V, the number was set at seventy, divided among fourteen cardinal-deacons, fifty cardinal-priests, and six cardinal-bishops.
Under the terms of Pope Paul VI's motu proprioIngravescentem Aetatem, cardinals who reached the age of 80 before a conclave opened had no vote in papal elections. Pope John Paul II's Universi Dominici Gregis of 22 February 1996 modified that slightly, so that cardinals who have reached the age of 80 before the day the see becomes vacant do not have a vote.
Although the canonical qualifications required of candidates for episcopacy leave a broad field open to the cardinals, they have for over six centuries elected one of their own number to be Bishop of Rome. The last time they chose someone who was not a cardinal was at the 1378 election of Pope Urban VI. The conclave rules specify the procedures to be followed, should someone residing outside Vatican City or not yet a bishop be elected.
The following is the list of all Cardinals living as of 22 February 2014. Cardinals appear in order of precedence, based on seniority by date of appointment. Paulo Evaristo Arns is the most senior member of the College by length of service (the Protopriest) and the last survivor from the 1973 consistory. Angelo Sodano has the highest precedence as a Cardinal Bishop and Dean of the College of Cardinals. As of February 2014[update], the oldest living Cardinal is Loris Francesco Capovilla, born in 1915.
Within the College of Cardinals, there are three categories, the highest-ranked Cardinal Bishops, then Cardinal Priests, and finally Cardinal Deacons. Within each category the Cardinals are ranked by seniority of appointment. Since the pontificate of Pope John XXIII, despite these titles, almost all Cardinals who were not already bishops at the time their appointment was announced have been ordained bishops prior to the conclusion of the formal installation, though from the late 20th century Jesuit priests made cardinals when already over 80 have usually petitioned not to become bishops and have received permission in this sense.

The College currently has 199 members, 106 of whom have voting rights. The group's size at any given moment has historically been limited by popes, ecumenical councils, and even the College itself. Over the period from 1099 to 1986, the total number of cardinals appointed was approximately 2900 (excluding possible undocumented 12th century cardinals, cardinals appointed during the Western Schism by pontiffs now considered to be antipopes, and subject to some other sources of uncertainty), nearly half of whom were created after 1655.
^ abIn 2003 Pope John Paul II announced he was also creating one cardinal secretly (in pectore). This appointment would have taken effect if it had been announced before the Pope's death. There was press speculation that it was his senior personal secretary, Stanisław Dziwisz, or a resident of the mainland of the People's Republic of China. On 6 April 2005 the Vatican spokesman revealed that Pope John Paul II had not announced the name of this cardinal before witnesses prior to his death and that the appointment was therefore null.
