Jaghbub (Arabic: الجغبوب, Italian: Giarabub) is a remote desert oasis village in the eastern Libyan Desert. It is actually closer to the Egyptian town of Siwa than to any Libyan town of note. The oasis is located in Butnan District and is the administrative seat of the Jaghbub Basic People's Congress. Supported by reservoirs of underground water and date production, the town is best known for its hard-won self-sufficiency. Idris of Libya was born in Jaghbub on 12 March 1890.
The Jaghbub oasis is located in a deep depression that extends below sea level. This depression, an area lower than the surrounding region, reaches to about -10 m. To the east the Siwa Oasis lies in a similar depression and even further east the large Qattara Depression also lies below sea level.
It was once the headquarters of the Senussi Movement and home of a long disappeared Islamic university and the former Senussi palace (which is now in rubble). Jaghbub was a part of Egypt until December 1925, when it was ceded to Italy as part of a deal to fix the Egypt-Libya border. In February 1931 the Italian colonial administration led by Marshal Rodolfo Graziani decided to build a barbed-wire fence stretching from the Mediterranean port of Bardia to Jaghbub 270 km away. Supervised by armoured patrols and the air force, the fence sought to cut off the rebels from their supply sources and contacts with the Senussi leadership in Egypt. The construction of the fence began in April, 1931 and was completed in September. This, along with the deportation of almost the entire population of the Jebel Akhdar, was decisive and precipitated the end of the rebellion. The fence still runs along the Libyan-Egyptian border from near Tobruk, finishing at Jaghbub where the desolate Great Sand Sea begins.
The oasis was the scene of an action fought between Commonwealth and Italian forces during World War II. Italian and Libyan colonial troops led by Colonel Salvatore Castagna resisted for nine months the siege by British troops of vastly superior number. The siege ended with the conquest of Jaghbub on 21 March 1941. The heroic resistance of the Italian troops was vastly celebrated by the fascist regime and used to minimize the military defeat in Cyrenaica.
