NWA meaning in Regional ?

The Maghreb (; Arabic: المغرب‎ al-Maghrib, "the west"), also known as Northwest Africa and the Arab Maghreb (المغرب العربي al-Maghrib al-Arabi), is the western part of North Africa and the Arab world. The region includes Algeria, Libya, Mauritania (also considered part of West Africa), Morocco and Tunisia. The Maghreb also includes the disputed territories of Western Sahara (controlled mostly by Morocco and partly by the self-proclaimed Sahrawi Arab Democratic Republic) and the Spanish cities Ceuta and Melilla. As of 2018, the region had a population of over 100 million people.

Through the eighteenth and nineteenth centuries, English sources often referred to the region as the Barbary Coast or the Barbary States, a term derived from the demonym of the Berbers. Sometimes, the region is referred to as the Land of the Atlas, referring to the Atlas Mountains, which are located within it. In Berber languages, the word "Tamazgha" is used to refer to the Maghreb region plus the smaller parts of Mali, Niger, Egypt and the Spanish Canary Islands that have traditionally been inhabited by the Berbers.

The Maghreb is usually defined as encompassing much of the northern part of Africa, including a large portion of the Sahara Desert, but excluding Egypt and Sudan, which are considered to be located in the Mashriq — the eastern part of the Arab world. The traditional definition of the Maghreb — which restricted its scope to the Atlas Mountains and the coastal plains of Morocco, Algeria, Tunisia and Libya — was expanded in modern times to include Mauritania and the disputed territory of Western Sahara. During the era of Al-Andalus on the Iberian Peninsula (711–1492), the Maghreb's inhabitants — the Muslim Berbers, or Maghrebi — were known by Europeans as the "Moors".

Before the establishment of modern nation states in the region during the 20th century, the Maghreb most commonly referred to a smaller area, between the Mediterranean Sea and the Atlas Mountains in the south. It often also included the territory of eastern Libya, but not modern Mauritania. As recently as the late 19th century, the term "Maghreb" was used to refer to the Western Mediterranean region of coastal North Africa in general, and to Algeria, Morocco and Tunisia, in particular.

During the rule of the Berber kingdom of Numidia, the region was somewhat unified as an independent political entity. This period was followed by one of the Roman Empire's rule or influence. The Germanic Vandals invaded after that, followed by the equally brief re-establishment of a weak Roman rule by the Byzantine Empire. The Islamic Caliphates came to power under the Umayyad Caliphate, the Abbasid Caliphate and the Fatimid Caliphate. The most enduring rule was that of the local Berber empires of the Ifranid dynasty (also called Emirate of Tlemcen with abu Qurra as leader; the Berbers called him "caliph" Ibn Khaldun, as explained in his book Kitab al ibar), Almoravid dynasty, Almohad Caliphate, Hammadid dynasty, Zirid dynasty, Marinid dynasty, Zayyanid dynasty, Hafsid dynasty and Wattasid dynasty, extending from the 8th to 13th centuries. The Ottoman Empire for a period also controlled parts of the region.

Algeria, Libya, Mauritania, Morocco, and Tunisia established the Arab Maghreb Union in 1989 to promote cooperation and economic integration in a common market. It was envisioned initially by Muammar Gaddafi as a superstate. The union included Western Sahara implicitly under Morocco's membership, and ended Morocco's long cold war with Algeria over this territory. However, this progress was short-lived, and the union is now dormant.

Tensions between Algeria and Morocco over Western Sahara re-emerged, reinforced by the unsolved border dispute between the two countries. These two main conflicts have hindered progress on the union's joint goals and practically made it inactive as a whole. The instability in the region and growing cross-border security threats revived calls for regional cooperation. In May 2015 foreign ministers of the Arab Maghreb Union declared a need for coordinated security policy at the 33rd session of the follow-up committee meeting; this revived hope of some form of cooperation.
