Saeculum obscurum


Saeculum obscurum was a period in the history of the Papacy during the first two-thirds of the 10th century, beginning with the installation of Pope Sergius III in 904 and lasting for sixty 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.

Periodisation

The saeculum obscurum was first named and identified as a period of papal immorality by the Italian cardinal and historian Caesar Baronius in his Annales Ecclesiastici in the sixteenth century. Baronius's primary source for his history of this period was a contemporaneous writer, Bishop Liutprand of Cremona. Baronius himself was writing during the Counter-Reformation, a period of heightened sensitivity to clerical corruption. His characterisation of the early 10th-century papacy was perpetuated by Protestant authors. The terms "pornocracy", hetaerocracy and the Rule of the Harlots were coined by Protestant German theologians in the nineteenth century.
Historian Will Durant refers to the period from 867 to 1049 as the "nadir of the papacy".

10th-century popes

The Theophylacti family originated from Theophylactus. They held positions of increased importance in the Roman nobility such as Judex, vestararius, gloriosissimus dux, consul and senator, and magister militum. Theophylact's wife Theodora and daughter Marozia held a great influence over the papal selection and religious affairs in Rome through conspiracies, affairs, and marriages.
Marozia became the concubine of Pope Sergius III when she was 15 and later took other lovers and husbands. She ensured that her son John was seated as Pope John XI according to Antapodosis sive Res per Europam gestae, by Liutprand of Cremona. Liutprand affirms that Marozia arranged the murder of her former lover Pope John X through her then husband Guy of Tuscany possibly to secure the elevation of her current favourite as Pope Leo VI. There is no record substantiating that Pope John X had definitely died before Leo VI was elected since John X was already imprisoned by Marozia and was out of public view.
Theodora and Marozia held great sway over the popes during this time. In particular, as political rulers of Rome they had effective control over the election of new popes. Much that is alleged about the saeculum obscurum comes from the histories of Liutprand, Bishop of Cremona. Liutprand took part in the Assembly of Bishops which deposed Pope John XII and was a political enemy of the Roman aristocracy and its control over papal elections. Lindsay Brook writes:

List of Popes during the ''saeculum obscurum''

The Tusculan Papacy, 1012–1059

After several Crescentii family Popes up to 1012, the Theophylacti still occasionally nominated sons as Popes:
Pope Benedict IX went so far as to sell the Papacy to his religious Godfather, Pope Gregory VI. He then changed his mind, seized the Lateran Palace, and became Pope for the third time in 1047–48.
The Tusculan Papacy was finally ended by the election of Pope Nicholas II, who was assisted by Hildebrand of Sovana against Antipope Benedict X. Hildebrand was elected Pope Gregory VII in 1073 and introduced the Gregorian Reforms, increasing the power and independence of the papacy.
