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.

Nigeria, officially the Federal Republic of Nigeria, is a country in West Africa. It is situated between the Sahel to the north and the Gulf of Guinea in the Atlantic Ocean to the south. It covers an area of 923,769 square kilometres (356,669 sq mi). With a population of more than 236 million, it is the most populous country in Africa, and the world's sixth-most populous country. Nigeria borders Niger in the north, Chad in the northeast, Cameroon in the east, and Benin in the west. Nigeria is a federal republic comprising 36 states and the Federal Capital Territory, where its capital, Abuja, is located. The largest city in Nigeria by population is Lagos, one of the largest metropolitan areas in the world and the largest in Africa.

Nigeria has been home to several indigenous material cultures, pre-colonial states and kingdoms since the second millennium BC. The Nok culture, c. 1500 BC, marks one of the earliest known civilisations in the region. The Hausa Kingdoms inhabited the north, with the Edo Kingdom of Benin in the south, Igbo Kingdom of Nri in the southeast and in the southwest, the Oyo Empire. The present day territory of Nigeria was home to a vast array of city-states. In the early 19th century the Fula jihads culminated in the Sokoto Caliphate. The modern state originated with British colonialization in the 19th century, taking its present territorial shape with the merging of the Southern Nigeria Protectorate and the Northern Nigeria Protectorate in 1914. The British set up administrative and legal structures and incorporated traditional monarchs as a form of indirect rule. Nigeria became a formally independent federation on 1 October 1960. It experienced a civil war from 1967 to 1970, followed by a succession of military dictatorships and democratically elected civilian governments until achieving a stable government in the 1999 Nigerian presidential election.

The Organisation of African, Caribbean and Pacific States (OACPS, French: Organisation des États d'Afrique, des Caraïbes et du Pacifique) is a group of countries in Africa, the Caribbean, and the Pacific Islands that was created by the Georgetown Agreement in 1975. Formerly known as African, Caribbean and Pacific Group of States (ACP), the organisation's main objectives are sustainable development and poverty reduction within its member states, as well as their greater integration into the world's economy. All of the member states, except Cuba, are signatories to the Cotonou Agreement with the European Union.

The Cotonou Agreement (signed in Cotonou, Benin, in June 2000) is the successor to the Lomé Conventions. One of the major differences from the Lomé Convention is that the partnership is extended to new actors such as civil society, private sector, trade unions and local authorities. These will be involved in consultations and planning of national development strategies, provided with access to financial resources and involved in the implementation of programmes.

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.

Burkina Faso is a landlocked country in West Africa, bordered by Mali to the northwest, Niger to the northeast, Benin to the southeast, Togo and Ghana to the south, and Ivory Coast to the southwest. It covers an area of 274,223 km (105,878 sq mi). In 2024, the country had an estimated population of approximately 23,286,000. Called the Republic of Upper Volta from 1958 to 1984, it was renamed Burkina Faso by president Thomas Sankara. Its citizens are known as Burkinabes, and its capital and largest city is Ouagadougou.

The largest ethnic group in Burkina Faso is the Mossi people, who settled the area in the 11th and 13th centuries. They established kingdoms such as Ouagadougou, Tenkodogo, and Yatenga. In 1896, it was colonized by the French as part of French West Africa; in 1958, Upper Volta became a self-governing colony within the French Community. In 1960, it gained full independence with Maurice Yaméogo as president. Since it gained its independence, the country has been subject to instability, droughts, famines, and corruption. There have also been various coups, in 1966, 1980, 1982, 1983, 1987, and twice in 2022 (January and September). There were also unsuccessful coup attempts in 1989, 2015, and 2023.

French West Africa (French: Afrique-Occidentale française, AOF) was a federation of eight French colonial territories in West Africa: Mauritania, Senegal, French Sudan (now Mali), French Guinea (now Guinea), Ivory Coast, Upper Volta (now Burkina Faso), Dahomey (now Benin) and Niger. The federation existed from 1895 until 1958. Its capital was Saint-Louis in Senegal until 1902, and then Dakar until the federation's collapse in 1960.

With an area of 4,689,000 km, French West Africa was eight times the size of Metropolitan France. French Equatorial Africa had an additional area of 2,500,000 km.

The Organisation of Islamic Cooperation founded in 1969. It has 57 members. 49 of the member countries have a Muslim majority although two of them namely, Guinea-Bissau and Cote d'Ivoire, have less than 50% Muslim population. Cameroon, Benin, Mozambique, Togo, Uganda, Suriname, Gabon, and Guyana are the full members with Christian majority populations.

The Nilo-Saharan languages are a proposed family of around 210 African languages spoken by somewhere around 70 million speakers, mainly in the upper parts of the Chari and Nile rivers, including historic Nubia, north of where the two tributaries of the Nile meet. The languages extend through 17 nations in the northern half of Africa: from Algeria to Benin in the west; from Libya to the Democratic Republic of the Congo in the centre; and from Egypt to Tanzania in the east.

As indicated by its hyphenated name, Nilo-Saharan is a family of the African interior, including the greater Nile Basin and the Central Sahara Desert. Most of its proposed constituent divisions are found in the modern countries of Sudan and South Sudan, through which the Nile River flows.
