Simony in the context of "Béla III of Hungary"

Pope Gregory VII (Latin: Gregorius VII; c. 1015 – 25 May 1085), born Hildebrand of Sovana (Italian: Ildebrando di Soana), was head of the Catholic Church and ruler of the Papal States from 22 April 1073 to his death in 1085. He is venerated as a saint in the Catholic Church.

One of the great reforming popes, he initiated the Gregorian Reform, and is perhaps best known for the part he played in the Investiture Controversy, his dispute with Emperor Henry IV to establish the primacy of papal authority and the new canon law governing the election of the pope by the College of Cardinals. He was also at the forefront of developments in the relationship between the emperor and the papacy during the years before he became pope. He was the first pope to introduce a policy of obligatory celibacy for the clergy, which had until then commonly married, and also attacked the practice of simony.

Henry IV (German: Heinrich IV; 11 November 1050 – 7 August 1106) was Holy Roman Emperor from 1084 to 1105, King of Germany from 1054 to 1105, King of Italy and Burgundy from 1056 to 1105, and Duke of Bavaria from 1052 to 1054. He was the son of Henry III, Holy Roman Emperor—the second monarch of the Salian dynasty—and Agnes of Poitou. After his father's death on 5 October 1056, Henry was placed under his mother's guardianship. She made grants to German aristocrats to secure their support. Unlike her late husband, she could not control the election of the popes, thus the idea of the "liberty of the Church" strengthened during her rule. Taking advantage of her weakness, Archbishop Anno II of Cologne kidnapped Henry in April 1062. He administered Germany until Henry came of age in 1065.

Henry endeavoured to recover the royal estates that had been lost during his minority. He employed low-ranking officials to carry out his new policies, causing discontent in Saxony and Thuringia. Henry crushed a riot in Saxony in 1069 and overcame the rebellion of the Saxon aristocrat Otto of Nordheim in 1071. The appointment of commoners to high office offended German aristocrats, and many of them withdrew from Henry's court. He insisted on his royal prerogative to appoint bishops and abbots, although the reformist clerics condemned this practice as simony (a forbidden sale of church offices). Pope Alexander II blamed Henry's advisors for his acts and excommunicated them in early 1073. Henry's conflicts with the Holy See and the German dukes weakened his position and the Saxons rose up in open rebellion in the summer of 1074. Taking advantage of a quarrel between the Saxon aristocrats and peasantry, he forced the rebels into submission in October 1075.

Pope Boniface VIII (Latin: Bonifacius PP. VIII, Italian: Bonifacio VIII; born Benedetto Caetani; c. 1230 – 11 October 1303) was head of the Catholic Church and ruler of the Papal States from 24 December 1294 until his death in 1303. The Caetani family was of baronial origin with connections to the papacy. He succeeded Pope Celestine V, who had abdicated from the papal throne. Boniface spent his early pontificate abroad in diplomatic roles.

Boniface VIII put forward some of the strongest claims of any pope to temporal as well as spiritual power. He involved himself often with foreign affairs, including in France, Sicily, Italy, and the First War of Scottish Independence. These views, and his chronic intervention in temporal affairs, led to many bitter quarrels with Albert I of Germany, Philip IV of France, and Dante Alighieri, who expected the pope to soon arrive at the eighth circle of Hell in his Divine Comedy, among the simoniacs.

The Charter of Liberties (Latin: Carta Libertatum), also called the Coronation Charter, or Statutes of the Realm, was a written proclamation by Henry I of England, issued upon his accession to the throne in 1100. It sought to bind the King to certain laws regarding the treatment of nobles, church officials, and individuals. The nineteenth-century historians Frederick Maitland and Frederick Pollock considered it a landmark document in English legal history and a forerunner of Magna Carta. It was issued in Latin, Anglo-Norman and Old English versions, a sign of the increasing status of the English language at the time.

The document addressed abuses of royal power by his predecessor William II (Henry's brother, r. 1087–1100), as perceived by the nobility, specifically the over-taxation of the barons, the abuse of vacant sees, and the practices of simony and pluralism.

Jan Hus (/hʊs/; Czech: [ˈjan ˈɦus] ; c. 1369 – 6 July 1415), sometimes anglicized as John Goose or John Huss, and referred to in historical texts as Iohannes Hvs or Johannes Huss, was a Czech theologian and philosopher who became a Church reformer and the inspiration of Hussitism, a key predecessor to Protestantism, and a seminal figure in the Bohemian Reformation. Hus is considered to be the first Church reformer, even though some designate the theorist John Wycliffe. His teachings had a strong influence, most immediately in the approval of a reformed Bohemian religious denomination and, over a century later, on Martin Luther.

After being ordained as a Catholic priest, Hus began to preach in Prague. He opposed many aspects of the Catholic Church in Bohemia, such as its views on ecclesiology, simony, the Eucharist, and other theological topics. Hus was a master, dean, and rector at the Charles University in Prague between 1409 and 1410.

Eligius (French: Éloi; 11 June 588 – 1 December 660), venerated as Saint Eligius, was a Frankish goldsmith, courtier, and bishop who was chief counsellor to Dagobert I and later Bishop of Noyon–Tournai. His deeds were recorded in Vita Sancti Eligii, written by his friend Audoin of Rouen.

Born into a Gallo-Roman family, Eligius found success as a goldsmith at the Merovingian royal court of Clotaire II and served as chief counsellor to Dagobert I until Dagobert's death in 639. Under the subsequent regency of Nanthild, the queen consort, Eligius was ordained a priest and campaigned against simony in the Church. Appointed Bishop of Noyon–Tournai in 642, he founded many monasteries and churches while working to convert the pagan population of Flanders to Christianity.

Pope Callixtus II or Callistus II (c. 1065 – 13 December 1124), born Guy of Burgundy, was the head of the Catholic Church and ruler of the Papal States from February 1119 to his death in 1124. His pontificate was shaped by the Investiture Controversy, which he was able to settle through the Concordat of Worms in 1122.

As son of Count William I of Burgundy, Guy was a member of and connected to the highest nobility in Europe. He became archbishop of Vienne and served as papal legate to France. He attended the Lateran Synod of 1112. He was elected pope at Cluny in 1119. The following year, prompted by attacks on Jews, he issued the bull Sicut Judaeis which forbade Christians, on pain of excommunication, from forcing Jews to convert, from harming them, from taking their property, from disturbing the celebration of their festivals, and from interfering with their cemeteries. In March 1123, Calixtus II convened the First Lateran Council which passed several disciplinary decrees, such as those against simony and concubinage among the clergy, and violators of the Truce of God.
