Libya, officially the State of Libya, is a country in the Maghreb region of North Africa. It borders the Mediterranean Sea to the north, Egypt to the east, Sudan to the southeast, Chad to the south, Niger to the southwest, Algeria to the west, and Tunisia to the northwest. With an area of almost 1.8 million km (700,000 sq mi), Libya is the fourth-largest country in Africa and the Arab world, and the 16th-largest in the world. The country claims 32,000 square kilometres of southeastern Algeria, south of the Libyan town of Ghat. The capital and largest city is Tripoli, located in the northwest and contains over a million of Libya's 7 million people.

Libya has been inhabited by Berbers since the late Bronze Age as descendants from Iberomaurusian and Capsian cultures. In classical antiquity, the Phoenicians established city-states and trading posts in western Libya, while several Greek cities were established in the East. Parts of Libya were variously ruled by Carthaginians, Numidians, Persians, and Greeks before the entire region became a part of the Roman Empire. Libya was an early centre of Christianity. After the fall of the Western Roman Empire, the area of Libya was mostly occupied by the Vandals until the 7th century when invasions brought Islam to the region. From then on, centuries of Arab migration to the Maghreb shifted the demographic scope of Libya in favour of Arabs. In the 16th century, the Spanish Empire and the Knights Hospitaller occupied Tripoli until Ottoman rule began in 1551. Libya was involved in the Barbary Wars of the 18th and 19th centuries. Ottoman rule continued until the Italo-Turkish War in 1911, which resulted in Italy occupying Libya and establishing two colonies: Italian Tripolitania and Italian Cyrenaica, later unified in the Italian Libya colony from 1934 to 1943.

Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Libya to the northwest, Egypt to the north, the Red Sea to the east, Eritrea and Ethiopia to the southeast, and South Sudan to the south. Sudan has a population of 50 million people as of 2024 and occupies 1,886,068 square kilometres (728,215 square miles), making it Africa's third-largest country by area. Sudan's capital and most populous city is Khartoum.

The area that is now Sudan witnessed the Khormusan (c. 40000–16000 BC), Halfan culture (c. 20500–17000 BC), Sebilian (c. 13000–10000 BC), Qadan culture (c. 15000–5000 BC), the war of Jebel Sahaba, the earliest known war in the world, around 11500 BC, A-Group culture (c. 3800–3100 BC), Kingdom of Kerma (c. 2500–1500 BC), the Egyptian New Kingdom (c. 1500–1070 BC), and the Kingdom of Kush (c. 785 BC – 350 AD). After the fall of Kush, the Nubians formed the three Christian kingdoms of Nobatia, Makuria, and Alodia. Between the 14th and 15th centuries, most of Sudan was gradually settled by Arab nomads. From the 16th to the 19th centuries, central and eastern Sudan were dominated by the Funj sultanate, while Darfur ruled the west and the Ottomans the east.

The Khedivate of Egypt (Arabic: الْخُدَيْوِيَّةُ الْمِصْرِيَّةُ or خُدَيْوِيَّةُ مِصْرَ, Egyptian Arabic pronunciation: [xedeˈwejjet mɑsˤɾ]; Ottoman Turkish: خدیویت مصر Hıdiviyet-i Mısır) was an autonomous tributary state of the Ottoman Empire established and ruled by the Muhammad Ali Dynasty following the defeat and expulsion of Napoleon Bonaparte's forces, ending the short-lived French occupation of Lower Egypt. The Khedivate of Egypt had also expanded to control present-day Sudan, South Sudan, Eritrea, Djibouti, northwestern Somalia, northeastern Ethiopia, Lebanon, Jordan, Israel, Palestine, Syria, Greece, Cyprus, southern and central Turkey, in addition to parts from Libya, Chad, Central African Republic, Democratic Republic of Congo, and Uganda, as well as northwestern Saudi Arabia, parts of Yemen and the Kingdom of Hejaz.

The United Kingdom invaded and took control in 1882. In 1914, the Ottoman Empire connection was ended and Britain established a protectorate called the Sultanate of Egypt.

The Maliki school or Malikism is one of the four major schools of Islamic jurisprudence within Sunni Islam. It was founded by Malik ibn Anas (c. 711–795 CE) in the 8th century. In contrast to the Ahl al-Hadith and Ahl al-Ra'y schools of thought, the Maliki school takes a unique position known as Ahl al-Amal, in which they consider the Sunnah to be primarily sourced from the practice of the people of Medina and living Islamic traditions for their rulings on Islamic law.

The Maliki school is one of the largest groups of Sunni Muslims, comparable to the Shafi’i madhhab in adherents, but smaller than the Hanafi madhhab. Sharia based on Maliki Fiqh is predominantly found in North Africa (excluding parts of Egypt), West Africa, Chad, Sudan and the Persian Gulf.

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 Economic and Monetary Community of Central Africa, generally referred to by its French acronym CEMAC (for Communauté Économique et Monétaire de l'Afrique Centrale; Spanish: Comunidad Económica y Monetaria de África Central), is an organization of states of Central Africa established by Cameroon, Central African Republic, Chad, the Republic of the Congo, Equatorial Guinea and Gabon to promote economic integration among countries that share a common currency, the Central African CFA franc.

There is a strong overlap between CEMAC and Economic Community of Central African States (ECMAS) in the areas of membership and mandates.

The Central African CFA franc (French: franc CFA or simply franc; ISO code: XAF; abbreviation: F.CFA) is the currency of six independent states in Central Africa: Cameroon, Central African Republic, Chad, Republic of the Congo, Equatorial Guinea and Gabon. These six countries had a combined population of 55.2 million in 2020, and a combined GDP of over US$100 billion (as of 2021).

CFA originally stood for Colonies françaises d'Afrique ("French colonies of Africa"); following the independence of these states, its name was changed to Communauté financière africaine ("African Financial Community"). The currency is issued by the Bank of Central African States (BEAC; Banque des États de l'Afrique Centrale), located in Yaoundé, Cameroon, for the members of the Economic and Monetary Community of Central Africa (CEMAC; Communauté Économique et Monétaire de l'Afrique Centrale). The franc is nominally subdivided into 100 centimes but no centime denominations have 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 Libya–Sudan border is 382 km (237 mi) in length and runs from the tripoint with Egypt in the north to the tripoint with Chad in the south.

The Libya–Niger border is 342 kilometres (213 miles) in length and runs from the tripoint with Algeria in the west to the tripoint with Chad in the east.

Below is a list of countries in Africa by area.

Africa is the second-largest continent in the world by area and population. Algeria has been the largest country in Africa and the Arab world since the division of the Sudan in 2011. The largest African country in sub-Saharan Africa is the Democratic Republic of the Congo. Located in Central Africa, DR Congo is also the second-largest country on the continent. Also located in Central Africa, Chad is the continent's largest landlocked country. Madagascar is the largest island country in Africa, it is also the second-largest island country in the world, only behind Indonesia.

Gherardo Gambeli (born 23 June 1969) is an Italian Catholic prelate who has served as Archbishop of Florence since 2024. He devoted more than a decade of his time as a priest to missionary work in Chad.

The Central African Republic (CAR) is a landlocked country in Central Africa. It is bordered by Chad to the north, Sudan to the northeast, South Sudan to the east, the Democratic Republic of the Congo to the south, the Republic of the Congo to the southwest, and Cameroon to the west. Bangui is the country's capital and largest city, bordering the Democratic Republic of the Congo. The Central African Republic covers a land area of about 620,000 square kilometres (240,000 sq mi). As of 2024, it has a population of 5,357,744, consisting of about 80 ethnic groups, and is in the scene of a civil war, which has been ongoing since 2012. Having been a French colony under the name Ubangi-Shari, French is the official language, with Sango, a Ngbandi-based creole language, as the national and co-official language.

The Central African Republic mainly consists of Sudano-Guinean savanna, but the country also includes a Sahelo-Sudanian zone in the north and an equatorial forest zone in the south. Two-thirds of the country is within the Ubangi River basin (which flows into the Congo), while the remaining third lies in the basin of the Chari, which flows into Lake Chad.

Central Africa (French: Afrique centrale; Spanish: África central; Portuguese: África Central) is a subregion of the African continent comprising various countries according to different definitions. Middle Africa is an analogous term used by the United Nations in its geoscheme for Africa and consists of the following countries: Angola, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Republic of the Congo, Equatorial Guinea, Gabon, and São Tomé and Príncipe. The United Nations Office for Central Africa also includes Burundi and Rwanda in the region, which are considered part of East Africa in the geoscheme. These eleven countries are members of the Economic Community of Central African States (ECCAS). Six of those countries (Cameroon, Central African Republic, Chad, Equatorial Guinea, Gabon, and Republic of the Congo) are also members of the Economic and Monetary Community of Central Africa (CEMAC) and share a common currency, the Central African CFA franc.

The African Development Bank, on the other hand, defines Central Africa as seven countries: Cameroon, Central African Republic, Chad, Republic of the Congo, Democratic Republic of Congo, Equatorial Guinea, and Gabon.

Cameroon, officially the Republic of Cameroon, is a country in Central Africa. It shares boundaries with Nigeria to the west and north, Chad to the northeast, the Central African Republic to the east, and Equatorial Guinea, Gabon, and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea, and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both geostrategic locations. Cameroon's population of nearly 31 million people speak 250 native languages, in addition to the national tongues of English and French. The capital city of the country is Yaoundé.

Early inhabitants of the territory included the Sao civilisation around Lake Chad and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century. Fulani soldiers founded the Adamawa Emirate in the north in the 19th century, and various ethnic groups of the west and northwest established powerful chiefdoms and fondoms.

Minṭaqah (Arabic: مِنْطَقَة [ˈmintˤaqah]; plural مَنَاطِق manāṭiq [maˈnaːtˤiq]) is a term used for a first-level administrative division in Saudi Arabia and Chad and for a second-level administrative division in several other Arab countries. It is often translated as region or district, but the literal meaning is "region", "area", or even simply "place".

The Sahel region of Africa has long experienced a series of historic droughts, dating back to at least the 17th century. The Sahel region is a climate zone sandwiched between the Sudanian Savanna to the south and the Sahara desert to the north, across West and Central Africa. While the frequency of drought in the region is thought to have increased from the end of the 19th century, three long droughts have had dramatic environmental and societal effects upon the Sahel nations. Famine followed severe droughts in the 1910s, the 1940s, and the 1960s, 1970s and 1980s, although a partial recovery occurred from 1975-80. The most recent drought occurred in 2012.

While at least one particularly severe drought has been confirmed each century since the 17th century, the frequency and severity of recent Sahelian droughts stands out. Famine and dislocation on a massive scale—from 1968 to 1974 and again in the early and mid-1980s—was blamed on two spikes in the severity of the 1960-1980s drought period. From the late 1960s to early 1980s famine killed 100,000 people, left 750,000 dependent on food aid, and affected most of the Sahel's 50 million people. The economies, agriculture, livestock and human populations of much of Mauritania, Mali, Chad, Niger and Burkina Faso (known as Upper Volta during the time of the drought) were severely impacted. As disruptive as the droughts of the late 20th century were, evidence of past droughts recorded in Ghanaian lake sediments suggest that multi-decadal megadroughts were common in West Africa over the past 3,000 years and that several droughts lasted far longer and were far more severe.

The Bodélé Depression (pronounced [bɔ.de.le]), located at the southern edge of the Sahara Desert in north central Africa, is the lowest point in Chad. It is 500 km long, 150 km wide and around 160 m deep. Its bottom lies about 155 meters above sea level. The dry endorheic basin is a major source of fertile dust essential for the Amazon rainforest, with some studies suggesting that it supplies over half of the nutrient-rich dust that supports the rainforest.

Dust storms from the Bodélé Depression occur on average about 100 days per year, one typical example being the massive dust storms that swept over West Africa and the Cape Verde Islands in February 2004. As the wind sweeps between the Tibesti and the Ennedi Mountains in Northern Chad, it is channeled across the depression. The dry bowl that forms the depression is marked by a series of ephemeral lakes, many of which were last filled during wetter periods of the Holocene.

Patrolling is a military tactic. Small groups or individual units are deployed from a larger formation to achieve a specific objective and then return. The tactic of patrolling may be applied to ground troops, armored units, naval units, and combat aircraft. The duration of a patrol will vary from a few hours to several weeks depending on the nature of the objective and the type of units involved.

There are several different types of patrol each with a different objective. The most common is to collect information by carrying out a reconnaissance patrol. Such a patrol may try to remain clandestine and observe an enemy without themselves being detected. Other reconnaissance patrols are overt, especially those that interact with the civilian population.
