The diocese of Leptis Magna was an ancient bishopric in Africa with its episcopal see in Leptis Magna, modern Al-Khums in Libya. After the Muslim conquest of the Maghreb it was abandoned but reinstated as a titular see in the Catholic Church in 1925.
Leptis Magna had a bishop from the second century onwards. The first known person known to have served as bishop if a certain Victor who became pope in 189. [1] Bishop Archaeus composed a work on the dating of Easter around the year 200 and bishop Dioga participated at the Synod of 256 in Carthage. [2] The Synod of 484 in Carthage was attended by bishop Callipides of Leptis Magna. [3] After the Byzantine reconquest of Africa from the Vandals, a basilica [4] dedicated to the Theotokos was built in the town and the Nicene creed reintroduced.
The diocese was re-established as a titular see by the Catholic Church in the 20th century, first under the name Leptis Maior and since 1933 as Leptis Magna. [5]
