Erythrum


Erythrum was a city and bishopric in Roman Africa, which remains a Catholic titular see.
The city, identified with modern Uaili-Et-Trun, was important enough in the Roman province of Cyrenaica and later the split-off province Libya Superior or Libya Pentapolitana to become a suffragan of its capital's Metropolitan of Cyrene.
Cyrenaica was conquered by Muslim Arabs during the tenure of the second caliph, Omer Bin Khattab, in 643/44, After the breakdown of the Ummayad caliphate it was essentially annexed to Egypt, although still under the same name, first under the Fatimid caliphs and later under the Ayyubid and Mamluk sultanates. Ultimately, it was annexed by the Turkish Ottoman Empire in 1517 when it was part of the Tripolitania Vilayet.

Christian bishopric

The Diocese of Erythron was a center of Early Christianity in the Pentapolis of North Africa. It was an early Christian bishopric. The seat of the Diocese was the Roman town of Erython, tentatively identified with the village of Uaili-Et-Trun in today's Libya.
We know of four bishops of the diocese from antiquity.
The diocese was nominally restored in 1933 as Latin titular bishopric under the names of Erythrum / Eritro / Erythritan.,
It has been vacant for decades, having had the following incumbents, so far of the fitting Episcopal rank, including an Eastern Catholic :
