Pope Alexander VI was head of the Catholic Church and ruler of the Papal States from 11 August 1492 until his death in 1503. Born into the prominent Borgia family in Xàtiva in the Kingdom of Valencia under the Crown of Aragon, Spain, Rodrigo studied law at the University of Bologna. He was ordained deacon and made a cardinal in 1456 after the election of his uncle as Pope Callixtus III, and a year later he became vice-chancellor of the Catholic Church. He proceeded to serve in the Curia under the next four popes, acquiring significant influence and wealth in the process. In 1492, Rodrigo was elected pope, taking the name Alexander VI.
Pope Julius II was head of the Catholic Church and ruler of the Papal States from 1503 to his death, in February 1513. Nicknamed the Warrior Pope, the Battle Pope or the Fearsome Pope, it is often speculated that he had chosen his papal name not in honor of Pope Julius I but in emulation of Julius Caesar. One of the most powerful and influential popes, Julius II was a central figure of the High Renaissance and left a significant cultural and political legacy. As a result of his policies during the Italian Wars, the Papal States increased their power and centralization, and the office of the papacy continued to be crucial, diplomatically and politically, during the entirety of the 16th century in Italy and Europe.
Pope Sixtus IV was head of the Catholic Church and ruler of the Papal States from 9 August 1471 until his death.

Pope John XXII, born Jacques Duèze, was head of the Catholic Church from 7 August 1316 to his death, in December 1334.

Pope Paul IV, born Gian Pietro Carafa, was head of the Catholic Church and ruler of the Papal States from 23 May 1555 to his death, in August 1559. While serving as papal nuncio in Spain, he developed an anti-Spanish outlook that later coloured his papacy. In response to an invasion of part of the Papal States by Spain during his papacy, he called for a French military intervention. After a defeat of the French and with Spanish troops at the edge of Rome, the Papacy and Spain reached a compromise: French and Spanish forces left the Papal States and the Pope thereafter adopted a neutral stance between France and Spain.
Pope Pius IX was head of the Catholic Church from 1846 to 1878. His reign of nearly 32 years is the longest of any pope in history. He was notable for convoking the First Vatican Council in 1868 and for permanently losing control of the Papal States in 1870 to the Kingdom of Italy. Thereafter, he refused to leave Vatican City, declaring himself a "prisoner in the Vatican".
Baudouin was King of the Belgians from 17 July 1951 until his death in 1993. He was the last Belgian king to be sovereign of the Congo, before it became independent in 1960 and became the Democratic Republic of the Congo.
A military order is a Christian religious society of knights. The original military orders were the Knights Templar, the Knights Hospitaller, the Order of the Holy Sepulchre, the Order of Saint James, the Order of Calatrava, and the Teutonic Knights. They arose in the Middle Ages in association with the Crusades, in the Holy Land, the Baltics, and the Iberian peninsula; their members being dedicated to the protection of pilgrims and Christians, as well as the defence of the Crusader states. They are the predecessors of chivalric orders.

The Military Order of Our Lord Jesus Christ is the former order of Knights Templar as it was reconstituted in Portugal. Before 1910, it was known as the Royal Military Order of Our Lord Jesus Christ, and the Order of the Knights of Our Lord Jesus Christ. It was founded in 1319, with the protection of King Denis of Portugal, after the Templars were abolished on 22 March 1312 by the papal bull, Vox in excelso, issued by Pope Clement V. King Denis refused to pursue and persecute the former knights as had occurred in most of the other sovereign states under the political influence of the Catholic Church.
The Order of the Redeemer, also known as the Order of the Saviour, is an order of merit of Greece. The Order of the Redeemer is the oldest and highest decoration awarded by the modern Greek state.
An order of chivalry, order of knighthood, chivalric order, or equestrian order is an order of knights, typically founded during or inspired by the original Catholic military orders of the Crusades and paired with medieval concepts of ideals of chivalry.
Jus exclusivae was the right claimed by several Catholic monarchs of Europe to veto a candidate for the papacy. Although never formally recognized by the Catholic Church, the monarchs of France, Spain and Austria claimed this right at various times, making known to a papal conclave, through a crown-cardinal, that the monarch deemed a particular candidate for the papacy objectionable.
The Order of Pope Pius IX, also referred as the Pian Order, is a papal order of knighthood originally founded by Pope Pius IV in 1560. Currently, it is the highest honor conferred by the Holy See. The awarding of the order fell into disuse and was re-instituted by Pope Pius IX as a continuation on 17 June 1847.
The Sacred Military Constantinian Order of Saint George, also historically referred to as the Imperial Constantinian Order of Saint George and the Order of the Constantinian Angelic Knights of Saint George, is a dynastic order of knighthood of the House of Bourbon-Two Sicilies. Currently, the grand magistry of the order is disputed among the two claimants to the headship of the formerly reigning House of Bourbon-Two Sicilies as heirs of the House of Farnese, namely Prince Pedro and Prince Carlo. The order was one of the rare orders confirmed as a religious-military order in the papal bull Militantis Ecclesiae in 1718, owing to a notable success in liberating Christians in the Peloponnese. Together with the Sovereign Military Order of Malta, it is one of a small number of Catholic orders that still have this status today. It is not an order of chivalry under the patronage of the Holy See, but its membership is restricted to practising Catholics.
The Order of Saint Stephen is a Roman Catholic Tuscan dynastic military order founded in 1561. The order was created by Cosimo I de' Medici, first Grand Duke of Tuscany. The last member of the Medici dynasty to be a leader of the order was Gian Gastone de Medici in 1737. The order was permanently abolished in 1859 by the annexation of Tuscany to the Kingdom of Sardinia. The former Kingdom of Italy and the current Italian Republic also did not recognize the order as a legal entity but tolerates it as a private body.
The orders, decorations, and medals of the Holy See include titles, chivalric orders, distinctions and medals honoured by the Holy See, with the Pope as the fount of honour, for deeds and merits of their recipients to the benefit of the Holy See, the Catholic Church, or their respective communities, societies, nations and the world at large.
The papal nobility are the aristocracy of the Holy See, composed of persons holding titles bestowed by the Pope. From the Middle Ages into the nineteenth century, the papacy held direct temporal power in the Papal States, and many titles of papal nobility were derived from fiefs with territorial privileges attached. During this time, the Pope also bestowed ancient civic titles such as patrician. Today, the Pope still exercises authority to grant titles with territorial designations, although these are purely nominal and the privileges enjoyed by the holders pertain to styles of address and heraldry. Additionally, the Pope grants personal and familial titles that carry no territorial designation. Their titles being merely honorific, the modern papal nobility includes descendants of ancient Roman families as well as notable Catholics from many countries. All pontifical noble titles are within the personal gift of the pontiff, and are not recorded in the Official Acts of the Holy See.
