Djerba (ˈdʒɜːrbə,_ˈdʒɛərbə; Jirba, ˈʒɪrbæ; Meninge, Girba), also transliterated as Jerba or Jarbah, is a Tunisian island and the largest island of North Africa at , in the Gulf of Gabès, off the coast of Tunisia. It had a population of 139,544 at the 2004 census, which rose to 163,726 at the 2014 census. Citing the long and unique history of its Jewish minority in Djerba, Tunisia has sought UNESCO World Heritage status protections for the island.
Legend has it that Djerba was the island of the lotus-eaters where Odysseus was stranded on his voyage through the Mediterranean Sea.
The island was called Meninx (Μῆνιγξ) until the third century AD. Strabo writes that there was an altar of Odysseus.
The island was controlled twice by the Norman Kingdom of Sicily: in 1135–1158 and in 1284–1333. During the second of these periods it was organised as a feudal lordship, with the following Lords of Jerba:
1284–1305: Roger I
1305–1307, and 1307–1310: Roger II (twice)
1310: Charles
1310: Francis-Roger III
In the 14th century, the Borj El Kebir castle was built, on top of Roman ruins. The Tunisian government took possession of the castle in 1903, and later converted it into a museum.
An archaeological field survey of Djerba carried out between 1995 and 2000 under the auspices of the University of Pennsylvania, the American Academy in Rome and the Tunisian Institut National du Patrimoine, revealed over 400 archaeological sites, including many Punic and Roman villas and an amphitheatre.
According to their oral history, the Jewish minority has dwelled on the island continuously for more than 2,500 years. The first physical evidence that historians know of comes from the 11th century found in Cairo Geniza.
This community is unique in the Jewish diaspora for its unusually high percentage of Kohanim (Hebrew; the Jewish priestly caste), direct patrilineal descendants of Aaron the first high priest from Mosaic times. Local tradition holds that when Nebuchadnezzar II levelled Solomon's temple and laid waste to Judah and the city of Jerusalem in the year 586 BC, the Kohanim who settled in Djerba were among the refugees who were able to avoid slavery.
