Gregory I was the Count of Tusculum sometime between 954 and 1012. Consul et dux 961, vir illustrissimus 980, praefectus navalis 999. He was the son of Alberic II (son of Alberic I of Spoleto and Marozia), and Alda of Vienne (daughter of Hugh, King of Italy and his second wife, Alda (or Hilda)). His half-brother was Pope John XII.
He held the cities of Galeria, Arce, and Preneste and the title count palatine, the palace referred to being that of the Lateran. He was the first to carry the title "Count of Tusculum" and he passed it to all his descendants. They also received the titles of excellentissimus vir' (most excellent man) and apostolic rector of Sant'Andrea, which Gregory received in 980. In 981, Gregory bore the title Romanorum consul, dux et senator: "Consul, duke, and senator of the Romans."
As well as being an intimate and ally of the popes, especially Sylvester II, Gregory also served as praefectus navalis of Holy Roman Emperors Otto I and Otto II. However, on 6 February 1001, he was named "Head of the Republic" by the Romans for leading the revolt against Otto III and expelling the Crescentii. In 1002, the latter returned to power and he had to renounce his title.
His death is attested before the 11 June 1012, when his successor, Theophylact, was elected Pope.
By his wife Maria (died 1013) he had three sons and a daughter:
Pope Benedict VIII was bishop of Rome and ruler of the Papal States from 18 May 1012 until his death. He was born Theophylact to the noble family of the counts of Tusculum. Unusually for a medieval pope, he had strong authority both in Rome and abroad.
Pope Stephen VIII was the bishop of Rome and nominal ruler of the Papal States from 14 July 939 to his death. His pontificate occurred during the Saeculum obscurum, when the power of popes was diminished by the ambitious counts of Tusculum, and was marked by the conflict between his patron, Alberic II of Spoleto, and King Hugh of Italy.
Pope Sergius III was the bishop of Rome and nominal ruler of the Papal States from 29 January 904 to his death. He was pope during a period of violence and disorder in central Italy, when warring aristocratic factions sought to use the material and military resources of the papacy. At the behest of Theophylact I of Tusculum, Sergius seized the papal throne from Antipope Christopher, who in turn had deposed Pope Leo V. Sergius' reign was subsequently marked by Theophylact's influence. As pope, Sergius continued many ecclesiastical controversies of his predecessors, including conflict over Pope Formosus' legacy, annulling all ordinations made by the late pope, and the filioque controversy with eastern patriarchs. His pontificate was similarly marked by temporal conflicts, with Sergius' refusal to crown Berengar I of Italy as Holy Roman Emperor, and his support of Byzantine Emperor Leo VI the Wise's fourth marriage. Sergius also saw the restoration of the Lateran Palace.
Marozia, born Maria and also known as Mariuccia or Mariozza, was a Roman noblewoman who was the alleged mistress of Pope Sergius III and was given the unprecedented titles senatrix ("senatoress") and patricia of Rome by Pope John X.
Pope John XI was the bishop of Rome and nominal ruler of the Papal States from March 931 to his death. The true ruler of Rome at the time was his mother, Marozia, followed by his brother Alberic II. His pontificate occurred during the period known as Saeculum obscurum.
Pope John X was the bishop of Rome and nominal ruler of the Papal States from March 914 to his death. A candidate of the counts of Tusculum, he attempted to unify Italy under the leadership of Berengar of Friuli, and was instrumental in the defeat of the Saracens at the Battle of Garigliano. He eventually fell out with Marozia, who had him deposed, imprisoned, and finally murdered. John’s pontificate occurred during the period known as the Saeculum obscurum.
Saeculum obscurum, also known as the Pornocracy or the Rule of the Harlots, was a period in the history of the papacy during the first two thirds of the 10th century, following the chaos after the death of Pope Formosus in 896 which saw seven or eight papal elections in as many years. It began with the installation of Pope Sergius III in 904 and lasted for 60 years until the death of Pope John XII in 964. During this period, the popes were influenced strongly by a powerful and allegedly corrupt aristocratic family, the Theophylacti, and their relatives and allies. The era is seen as one of the lowest points of the history of the papal office.
The Duchy of Spoleto was a Lombard territory founded about 570 in central Italy by the Lombard dux Faroald. Its capital was the city of Spoleto.
Theophylact I was a medieval count of Tusculum who was the effective ruler of Rome from around 905 through to his death in 924. His descendants controlled the papacy for the next 100 years.
Theodora was a senatrix and serenissima vestaratrix of Rome. Theodora was married to Theophylact I, Count of Tusculum. The couple shared effective rulership of Rome between 905 and her death in 916.
Hugh, known as Hugh of Arles or Hugh of Provence, was the king of Italy from 926 until his death. He belonged to the Bosonid family. During his reign, he empowered his relatives at the expense of the aristocracy and tried to establish a relationship with the Byzantine Empire. He had success in defending the realm from external enemies, but his domestic habits and policies created many internal foes and he was removed from power before his death.
Alberic II (912–954) was ruler of Rome from 932 to 954, after deposing his mother Marozia and his stepfather, King Hugh of Italy.
The counts of Tusculum, also known as the Theophylacti, were a family of secular noblemen from Latium that maintained a powerful position in Rome between the 10th and 12th centuries. Several popes and antipopes during the 11th century came from their ranks. They created and perfected the political formula of noble-papacy, wherein the pope was arranged to be elected only from the ranks of the Roman nobles. The Pornocracy, the period of influence by powerful female courtesans of the family, also influenced papal history.
Alberic I was the Lombard Duke of Spoleto from between 896 and 900 until 920, 922, or thereabouts. He was also Margrave of Camerino, and the son-in-law of Theophylact I, Count of Tusculum, the most powerful man in Rome.
Crescentius the Elder, also known as Crescenzio de Theodora, was a politician and aristocrat in Rome who played a part in the papal appointment.
Gregory II was the son of Alberic III, Count of Tusculum and Ermelina. He was the Count of Tusculum and the Lateran from 1044 to his death.
Alberic III was the Count of Tusculum, along with Galeria, Preneste, and Arce, from 1024, when his brother the count Roman was elected Pope John XIX, until his own death. He was a son of Gregory I and Maria, brother of Popes Benedict VIII and John XIX, and brother-in-law of Thrasimund III of Spoleto.
Peter was a medieval Roman noble. Like his father, he carried the illustrious title of Romanorum patricius, consul, dux et senator, implying his secular command over Rome and its militia. He was the son of Alberic III, Count of Tusculum. As a result, he was a descendant of Theophylact I, Count of Tusculum.
The selection of the Pope, the Bishop of Rome and Supreme Pontiff of the Catholic Church, prior to the promulgation of In Nomine Domini in AD 1059 varied throughout history. Popes were often putatively appointed by their predecessors or by political rulers. While some kind of election often characterized the procedure, an election that included meaningful participation of the laity was rare, especially as the Popes' claims to temporal power solidified into the Papal States. The practice of papal appointment during this period would later result in the putative jus exclusivae, i.e., the claimed but invalid right to veto the selection that Catholic monarchs exercised into the twentieth century.
The Tusculan Papacy was a period of papal history from 1012 to 1048 where three successive relatives of the counts of Tusculum were installed as pope.
