Fetzara
Fetzara, a mixed Arabo-Berber tribe, province of Constantine, Algeria, in the hills of the Seybouse basin, south-east of Guelma. Originally the Fetzara were pure Arabs of the Ghatafan family, who formerly roamed the steppes of Cyrenaica, passing thence through Tunisia to Algeria, where they became amalgamated with the surrounding Berber populations. They give their name to the large lake or salt lagoon of Fetzara, which is supposed to have been formed by underground disturbances since their arrival in the country.
