Fadel
Fadel (properly Uled-Fedala), a historic Berber tribe of Algeria, province of Constantine, south-west of Batna; occupies the wooded slopes of the Aures mountains, where rises the Wed-Fedala, an affluent of the Biskra named from this tribe. The Fadels are mentioned by El-Bekri (11th century), and were formerly very powerful, but are now reduced to less than 2,000 souls.
