Berbers (Berber: "Mazices" / "Imaziɣen" / "Imazighen" singular: ⴰⵎⴰⵣⵉⵖ "Amaziɣ" / "Amazigh") are an ethnolinguistic group indigenous to North Africa.
 They are distributed in an area stretching from the Atlantic Ocean to the Siwa Oasis in Egypt, and from the Mediterranean Sea to the Niger River.
 Historically, they spoke Berber languages, which together form the Berber branch of the Afroasiatic family.
 Since the Muslim conquest of North Africa in the seventh century, a large number of Berbers inhabiting the Maghreb (Tamazgha) have acquired different degrees of knowledge of varieties of the languages of North Africa.
 After the colonization of North Africa by France, "the French government succeeded in integrating the French language in Algeria by making French the official national language and requiring all education to take place in French."
 Foreign languages, mainly French and to some degree Spanish, inherited from former European colonial powers, are used by most educated Berbers in Algeria and Morocco in some formal contexts, such as higher education or business.
Elephantaria in Mauretania was an ancient city in the Maghreb during the Roman, Byzantine and Vandal empires.
 It is shown on the Peutinger Table map.
Zohra is a 1922 silent 35 mm short film from Tunisia by Albert Samama ('Chikly').
 It was the first indigenous North African film production.
 The movie script was written by Chikly's daughter, Haydée Chikly, who also edited and starred as the key female protagonist in the film.
Mutugenna or Muttegena was a "colonia" (town) of the Roman, Berber and Vandal empires, located in the Maghreb.
 The city is generally identified with the ruins at Ain-Tebla in modern Algeria.
 Mutugenna was also the locus of a bishopric and was an important site in the development of the Donatist schism.
The Diocese of Pudentiana is a suppressed and titular See of the Roman Catholic Church.
 It was centered on the Roman town of Pudentiana that flourished in the Province of Numidia, Roman North Africa, through the Vandal and Roman Empires of late antiquity.
The Diocese of Tubia (Dioecesis Tubiensis) is a suppressed and titular see the province of Mauritania Caesariensis of the Roman Catholic Church.
 Tubia was a city in North Africa during the Roman, Byzantine and Vandal empires that is identifiable with the ruins of Henchir-Toubia (Qar`at aţ Ţūbīyah) in Modern Algeria.
North African climate cycles have a unique history that can be traced back millions of years.
 The cyclic climate pattern of the Sahara is characterized by significant shifts in the strength of the North African Monsoon.
 When the North African Monsoon is at its strongest annual precipitation and subsequent vegetation in the Sahara region increase, resulting in conditions commonly referred to as the "green Sahara".
 For a relatively weak North African Monsoon, the opposite is true, with decreased annual precipitation and less vegetation resulting in a phase of the Sahara climate cycle known as the "desert Sahara".
Tabuda or Thouda was a Roman–Berber colonia in the province of Mauretania Caesariensis.
 A key town in the Roman, Byzantine and Vandal empires, it is identifiable with the stone ruins at the oasis adjacent to the village of Sidi Okba, Algeria.
The North African hedgehog ("Atelerix algirus"), or Algerian hedgehog, is a species of mammal in the family Erinaceidae.
 It is found in Algeria, Libya, Malta, Morocco, Spain, and Tunisia.
 Little is known about this species of hedgehog, even though the most common breed of domesticated hedgehogs is a result of crossing a four-toed hedgehog with a North African hedgehog.
 Because this species of hedgehog is native to Africa, it has been suggested that it was introduced by humans to the other countries where it is now found, including France and Spain (including the Canary Islands).
 Of the four African species of hedgehogs, the North African hedgehog is the only one of these hedgehogs that can be found outside the continent of Africa.
 Because the North African hedgehog has such a wide habitat range and has a seemingly stable population , both in the wild and in the domesticated capacity, it does not appear to be at risk at this time.
Gilva was a Roman–Berber city in the province of Mauretania Caesariensis.
 It flourished during the Roman and Vandal empires.
 It was located to the south of Hippo Regius in present-day Algeria.
 The town existed from around 300 to 640AD.
