Patriarchate of Old Aquileia

The Patriarchate of Old Aquileia was created at the beginning of the 7th century, as a result of an internal schism within the Patriarchate of Aquileia. It was centered in the old Aquileia, that was held by the Lombards, while the rival Patriarchate of New Aquileia in Grado was under the Byzantine rule. Residence of the patriarchs of Old Aquileia was later moved, first to the city of Cormons, then to Cividale, and finally to Udine. Since 1077, patriarchs of Old Aquileia were also temporal lords of the Patriarchal State of Aquileia, that was annexed by the Venetian Republic in the first half of the 15th century, while the Patriarchate of Old Aquileia continued to exist as an ecclesiastical institution until 1751, when it was also abolished.
