Geography

Djelfa is located at an elevation of 3,734 feet (1,138 m) in the Ouled Naïl Range of north-central Algeria, between the towns of Bousaada and Laghouat. It is situated in a transitional zone between the dry, steppe-like Hautes Plaines (high plateaus) of the north, characterized by chotts (intermittent salt lakes), and the Sahara to the south. The town was founded in 1852 as a French military post on a geometric plan. It serves as an important livestock market centre for the semi-nomadic Ouled Naïl confederation. Djelfa is on the 12,000 mile-long Africa Trail.[citation needed]

History

The area is notable for its abundance of Neolithic rock carvings dating from 7000 to 5000 BC. North of Djelfa town there is an imposing physical feature known as Rocher de Sel (English: Salt Rock) that resulted from the erosion of rock salts and marls by rain.[1] To the west of the town Megalithic funerary structures are found.

During the Roman Empire a Roman town called Fallaba was built on the site of Djelfa.[2] That town lasted unto late antiquity.

In the 11th century, the Fatimids sent the Banu Hilal to the Tripolitania, Tunisia and Constantine areas against the Zirids.

During Philippe Pétain's period, a concentration camp was placed in Djelfa.[3]

Ecclesiastical history

During the Vandal Kingdom and Roman Empire the town was the seat of an ancient bishopric.[4][5] The bishopric was important enough in the Late Roman province of Numidia to become one of the many suffragan bishoprics of its Metropolitan Archbishopric in Carthage.[6][7]

It is possible that Christianity came to the town only after the rule of Constantine the Great, as there is no record of the bishopric under the Romans. The only known bishop of this African diocese is the Catholic bishop Salo mentioned in 484. This is considerably late compared to many of the other diocese in Numidia. Bishop Salo took part in the synod assembled in Carthage in 484 by the Arian ruler, Huneric of the Vandal Kingdom; after the Synod Salo was exiled (probably) to Vandal-controlled Sicily.

Like most bishoprics in Roman Africa, it faded after the Muslim conquest of the Maghreb.

Titular see

In 1933 the diocese was nominally restored as Latin Catholic titular bishopric.[8]

It has had the following incumbents, mostly of the fitting episcopal (lowest) rank with an archiepiscopal (intermediary) exception :

Culture

The inhabitants are also Ouled Naïl living in Biskra, M'Sila and in Saharan Atlas.

Climate

Djelfa has a semi-arid climate (Köppen climate classification BSk), with more precipitation in winter than in summer. Snow is not unusual in winter.
