List of African countries by area in the context of Chad

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.

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).

Seychelles (/seɪˈʃɛl(z)/ , /ˈseɪʃɛl(z)/; French: [sɛʃɛl] or [seʃɛl]), officially the Republic of Seychelles (French: République des Seychelles; Seychellois Creole: Repiblik Sesel), is an island country and archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is 1,500 kilometres (800 nautical miles) east of mainland Africa. Nearby island countries and territories include the Maldives, Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and the Chagos Archipelago to the east.Seychelles is the smallest country in Africa as well as the least populated sovereign African country, with an estimated population of 100,600 in 2022.

Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until it came under full British control in the early 19th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to a market-based diversified economy, characterised by service, public sector, and tourism activities. From 1976 to 2015, nominal GDP grew nearly 700%, and purchasing power parity nearly 1600%. Since the late 2010s, the government has taken steps to encourage foreign investment.

The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo, or more infrequently Zaire (its official name from 1971 to 1997), is a country in Central Africa. By land area, it is the second-largest country in Africa and the 11th-largest in the world. With a population of around 112 million, the DR Congo is the fourth-most populous in Africa and the most populous nominally Francophone country in the world. French is the official and most widely spoken language, though there are over 200 indigenous languages. The national capital and largest city is Kinshasa, which is also the economic center. The country is bordered by the Republic of the Congo, the Cabinda exclave of Angola, and the South Atlantic Ocean to the west; the Central African Republic and South Sudan to the north; Uganda, Rwanda, Burundi, and Tanzania (across Lake Tanganyika) to the east; and Zambia and Angola to the south. Centered on the Congo Basin, most of the country's terrain is covered by dense rainforests and is crossed by many rivers, while the east and southeast are mountainous.

The territory of the Congo was first inhabited by Central African foragers around 90,000 years ago and was settled in the Bantu expansion about 2,000 to 3,000 years ago. In the west, the Kingdom of Kongo ruled around the mouth of the Congo River from the 14th to the 19th century. In the center and east, the empires of Mwene Muji, Luba, and Lunda ruled between the 15th and 19th centuries. These kingdoms were broken up by Europeans during the colonization of the Congo Basin. King Leopold II of Belgium acquired rights to the Congo territory in 1885 and called it the Congo Free State. In 1908, Leopold ceded the territory after international pressure in response to widespread atrocities, and it became a Belgian colony. Congo achieved independence from Belgium in 1960 and was immediately confronted by a series of secessionist movements, the assassination of Prime Minister Patrice Lumumba, and the seizure of power by Mobutu Sese Seko in 1965. Mobutu renamed the country Zaire in 1971 and imposed a personalist dictatorship.

Angola, officially the Republic of Angola, is a country on the western coast of Southern Africa. It is the second-largest Portuguese-speaking (Lusophone) country after Brazil in both total area and population and is the seventh-largest country in Africa. It is bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to the west. Angola has an exclave province, the province of Cabinda, that borders the Republic of the Congo and the Democratic Republic of the Congo. The capital and most populous city is Luanda.

Angola has been inhabited since the Paleolithic Age. After the Bantu expansion reached the region, states were formed by the 13th century and organised into confederations. The Kingdom of Kongo ascended to achieve hegemony among the other kingdoms from the 14th century. Portuguese explorers established relations with Kongo in 1483. To the south were the kingdoms of Ndongo and Matamba, with the Ovimbundu kingdoms further south, and the Mbunda Kingdom in the east.

Mali, officially the Republic of Mali, is a landlocked country in West Africa. It is the eighth-largest country in Africa and the 23rd largest country in the world, with an area of over 1,240,192 square kilometres (478,841 sq mi). The country is bordered to the north by Algeria, to the east by Niger, to the northwest by Mauritania, to the south by Burkina Faso and Ivory Coast, and to the west by Guinea and Senegal. The population of Mali is about 23.29 million, 47.19% of which are estimated to be under the age of 15 in 2024. Its capital and largest city is Bamako. The country has 13 official languages, of which Bambara is the most commonly spoken.

The sovereign state's northern borders reach deep into the middle of the Sahara Desert. The country's southern part, where the majority of inhabitants live, is in the Sudanian savanna and has the Niger and Senegal rivers running through it. The country's economy centres on agriculture and mining with its most prominent natural resources including gold (of which it is the third largest producer in Africa) and salt.

The Gambia, officially the Republic of the Gambia, is a country in West Africa. Geographically, the Gambia is the smallest country in continental Africa; it is surrounded by Senegal on all sides except for the western part, which is bordered by the Atlantic Ocean.

Its territory is on both sides of the lower reaches of the Gambia River, which flows through the center of the country and empties into the Atlantic. The national namesake river demarcates the elongated shape of the country, which has an area of 11,300 square kilometres (4,400 sq mi) and a population of 2,422,712 people at the 1st of May 2024 Census which is a 30.45% population increase from 2013. The capital city is the island Banjul, formerly called Bathurst during the colonial era, which is the most extensive metropolitan area in the country. The second- and third-largest cities are Serekunda and Brikama. Other significant cities are Kanifing and Farafenni in the north bank, Basse in Upper River Region, and Soma in lower river region.

Algeria, officially the People's Democratic Republic of Algeria, is a country in the Maghreb region of North Africa. It covers an area of over 2,381,741 square kilometres (919,595 sq mi), and is the largest country in Africa and the tenth-largest country in the world by land area. With a population of 47 million, Algeria is the tenth-most populous country in 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. Algeria's 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.

The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo, or more infrequently Zaire (its official name from 1971 to 1997), is a country in Central Africa.
