Mali in the context of "Mauritania–Senegal border"

A failed state is a state that has lost its ability to fulfill fundamental security and development functions, lacking effective control over its territory and borders. Common characteristics of a failed state include a government incapable of tax collection, law enforcement, security assurance, territorial control, political or civil office staffing, and infrastructure maintenance. When this happens, widespread corruption and criminality, the intervention of state and non-state actors, the appearance of refugees and the involuntary movement of populations, sharp economic decline, and military intervention from both within and outside the state are much more likely to occur.

Originating in the 1990s, the term was initially applied to characterize the situation in Somalia. The country descended into disorder following a coup that ousted its dictator, Siad Barre, in 1991, leading to internal conflicts among the country's clans. In the early 2020s, Afghanistan, the Central African Republic, the Democratic Republic of the Congo, Haiti, Libya, Mali, Myanmar, Somalia, South Sudan, Sudan, Syria, and Yemen have all been described as failed states. There are concerns that Venezuela may be on path to becoming a failed state in the near future.

Berbers, or the Berber peoples, also known as Amazigh or Imazighen, are a diverse grouping of distinct ethnic groups indigenous to North Africa who predate the arrival of Arabs in the Maghreb. Their main connections are identified by their usage of Berber languages, most of them mutually unintelligible, which are part of the Afroasiatic language family.

They are indigenous to the Maghreb region of North Africa, where they live in scattered communities across parts of Morocco, Algeria, Libya, and to a lesser extent Tunisia, Mauritania, northern Mali and northern Niger (Azawagh). Smaller Berber communities are also found in Burkina Faso and Egypt's Siwa Oasis.

Mauritania, officially the Islamic Republic of Mauritania, is a country in Northwest Africa. It is bordered by the Atlantic Ocean to the west, Western Sahara to the north and northwest, Algeria to the northeast, Mali to the east and southeast, and Senegal to the southwest. By land area Mauritania is the 11th-largest country in Africa and the 28th-largest in the world; 90% of its territory is in the Sahara desert. Most of its population of some 4.3 million live in the temperate south of the country; roughly a third of the population is concentrated in the capital and largest city, Nouakchott, on the Atlantic coast.

The country's name derives from Mauretania, the Latin name for a region in the ancient Maghreb. It extended from central present-day Algeria to the Atlantic. Berbers occupied what is now Mauritania by the beginning of the 3rd century AD. Groups of Arab tribes migrated to this area in the late 7th century, bringing with them Islam, Arab culture, and the Arabic language. In the early 20th century, Mauritania was colonized by France as part of French West Africa. It achieved independence in 1960. However, the country has since experienced recurrent coups and periods of military dictatorship. The 2008 Mauritanian coup d'état was led by General Mohamed Ould Abdel Aziz, who won subsequent presidential elections in 2009 and 2014. He was succeeded by General Mohamed Ould Ghazouani following the 2019 elections, in what was considered the country's first peaceful transition of power since independence. Mauritania has a poor human rights record, particularly because of its perpetuation of slavery; the 2018 Global Slavery Index estimates there are about 90,000 slaves in the country (or 2.1% of the population).

Algeria, officially the People's Democratic Republic of Algeria, is a country in the Maghreb region of North Africa. It is bordered to the northeast by Tunisia; to the east by Libya; to the southeast by Niger; to the southwest by Mali, Mauritania, and Western Sahara; to the west by Morocco; and to the north by the Mediterranean Sea. The capital and largest city is Algiers, located in the far north on the Mediterranean coast.

Algeria has been at the crossroads of numerous cultures and civilisations for millennia, including the Phoenicians, Numidians, Romans, Vandals, and Byzantine Greeks. Its modern identity is rooted in centuries of Arab Muslim migration since the seventh century and the subsequent Arabisation of indigenous Berber populations. Following a succession of Islamic Arab and Berber dynasties between the eighth and 15th centuries, the Regency of Algiers was established in 1516 as a largely independent tributary state of the Ottoman Empire. After nearly three centuries as a major power in the Mediterranean, the country was invaded by France in 1830 and formally annexed in 1848, though it was not fully conquered and pacified until 1903. French rule brought mass European settlement that displaced the local population, which was reduced by up to one-third due to warfare, disease, and starvation. The Sétif and Guelma massacre in 1945 catalysed local resistance that culminated in the outbreak of the Algerian War in 1954. Algeria gained independence in 1962. It descended into a bloody civil war from 1992 to 2002, remaining in an official state of emergency until the 2010–2012 Algerian protests during the Arab Spring.

Niger, officially the Republic of the Niger, is a landlocked country in West Africa. It is a unitary state bordered by Libya to the northeast, Chad to the east, Nigeria to the south, Benin and Burkina Faso to the southwest, Mali to the west, and Algeria to the northwest. It covers a land area of almost 1.27 million km (490,000 sq mi), making it the largest landlocked country in West Africa and the second-largest landlocked nation in Africa behind Chad. Over 80% of its land area lies in the Sahara. Its predominantly Muslim population of about 25 million lives mostly in clusters in the south and west of the country. The capital, Niamey, is located in Niger's southwest corner along the namesake Niger River.

Following the spread of Islam to the region, Niger was on the fringes of some states, including the Kanem–Bornu Empire and the Mali Empire before more significant parts of its territory became included in states such as the Sultanate of Agadez and the Songhai Empire. It was colonized by France during the Scramble for Africa as part of French West Africa, becoming a distinct colony in 1922. Since obtaining independence in 1960, Niger has experienced five coups d'état and four periods of military rule. Niger's seventh and most recent constitution was enacted in 2010, establishing a multiparty, unitary semi-presidential system. Following the most recent coup in 2023, the country has been ruled by National Council for the Safeguard of the Homeland, a military junta.

The West African CFA franc (French: franc CFA or simply franc, ISO 4217 code: XOF; abbreviation: F.CFA) is the currency used by eight independent states in West Africa which make up the West African Economic and Monetary Union (UEMOA): Benin, Burkina Faso, Côte d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal and Togo. These eight countries had a combined population of 105.7 million people in 2014, and a combined GDP of US$128.6 billion as of 2018.

The initialism CFA stands for Communauté Financière Africaine (transl. African Financial Community). The currency is issued by the Central Bank of West African States (BCEAO; Banque Centrale des États de l'Afrique de l'Ouest), located in Dakar, Senegal, for the members of the UEMOA. The franc is nominally subdivided into 100 centimes but no coins or banknotes denominated in centimes have ever been issued. The production of CFA franc notes has been carried out at Chamalières by the Bank of France since its creation in 1945.

West Africa, also known as Western Africa, is the westernmost region of Africa. The United Nations defines Western Africa as the 16 countries of Benin, Burkina Faso, Cape Verde, The Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, and Togo, as well as Saint Helena, Ascension and Tristan da Cunha (a United Kingdom Overseas Territory). As of 2021, the population of West Africa is estimated at 419 million, and approximately 382 million in 2017, of which 189.7 million were female and 192.3 million male. The region is one of the fastest growing in Africa, both demographically and economically.

Historically, West Africa was home to several powerful states and empires that controlled regional trade routes, including the Mali and Gao Empires. Positioned at a crossroads of trade between North Africa and sub-Saharan Africa, the region supplied goods such as gold, ivory, and advanced iron-working. During European exploration, local economies were incorporated into the Atlantic slave trade, which expanded existing systems of slavery. Even after the end of the slave trade in the early 19th century, colonial powers — especially France and Britain — continued to exploit the region through colonial relationships. For example, they continued exporting extractive goods like cocoa, coffee, tropical timber, and mineral resources. Since gaining independence, several West African nations, such as the Ivory Coast, Ghana, Nigeria and Senegal — have taken active roles in regional and global economies.
