Since the thirteenth century it has been customary at Rome to confide to some particular Cardinal a special solicitude in the Roman Curia for the interests of a given religious order or institute, confraternity, church, college, city, nation etcetera. Such a person is known as a Cardinal Protector. He was its representative or orator when it sought a favor or a privilege, defended it when unjustly accused, and besought the aid of the Holy See when its rights, property or interests were violated or imperiled.

In ancient Rome a similar relationship had existed between the client (cliens) and his patronus (hence 'patron'); as Rome's power grew, a still closer analogy is visible between the Roman institution and the modern ecclesiastical protectorate. Nearly every provincial city had its patronus, or procurator, in imperial Rome, usually a Roman patrician or eques, and such persons were held in high esteem. Thus Cicero was patronus of Dyrrachium (later Durazzo, now Durrës) and of Capua, in which Campanian city a gilded statue was raised to him. In time the office became hereditary in certain families; Suetonius wrote, in his life of Tiberius, that the [imperial] Claudian family (gens Claudia) was from ancient times protector of Sicily and the Peloponnesus.
Every cardinal (except a Cardinal-Patriarch) is also, since the reign of John Paul II, called the Cardinal protector of the title (titular church s.s. for a Cardinal priest or Cardinal-deaconry for a Cardinal deacon) in or near Rome which he is assigned to, which gives him his title and benefits from his material support for upkeep or restoration, especially when he holds a rich see (usually as Archbishop).

The Roman Church adopted this, with many other imperial institutions, as one serviceable for external administration, not that the popes who first conferred this office and title sought to copy an ancient Roman usage, but because analogous conditions and circumstances created a similar situation. The office is conferred by the pope through the Cardinal secretary of state, sometimes by spontaneous designation of the Pope, sometimes at the request of those who seek such protection. Such a cardinal protector had the right to place his coat-of-arms on the church or main edifice of the institute, or on the municipal palace of the city in question.
The first to hold such an office was Cardinal Ugolino Conti (later Pope Gregory IX), who sought thereby to paralyze the intrigues of his many enemies at Rome; at the request of St. Francis himself, he was named protector of the Franciscans by Pope Innocent III, and again by Honorius III. Alexander IV and Nicholas III retained for themselves the office of protector of the Franciscans. Indeed, the latter were long the only order that boasted of a cardinal protector; it was only in the fourteenth century that gradually the office was extended. As early as 1370 Pope Gregory XI was obliged to restrain the abuses committed by the cardinal protector of the Franciscans; Pope Martin V (1417-31) forbade the acceptance by the protector of a religious order of any payment for his protection. While Sixtus IV and Julius II defined more particularly the limits of the office, Pope Innocent XII (1691-1700) must be credited with a lasting regulation of the duties and rights of a cardinal protector.
Kingdoms, empires etc. must have had cardinal protectors until Pope Urban VI (1378-89) forbade such cardinals to receive anything from the respective sovereigns of these states, lest through love of money they should be led to abet works of injustice. In 1424 Martin V forbade the cardinals to accept the protectorate of kings and princes, which prohibition was renewed in 1492 by Alexander VI. This prohibition was not renewed by Pope Leo X in the ninth session of the Lateran Council of 1512; the cardinals, however, were urged to exercise the office in an impartial way and without human respect. Until the Portuguese Revolution of 1910, the Kingdom of Portugal was the only state with a cardinal protector.
Within the papal curia, a cardinal is also appointed as protector of the Pontifical Ecclesiastical Academy which trains papal diplomats.
