1. Algeria (2,381,741 km2)
Algeria, officially the People's Democratic Republic of Algeria, is a country in the Maghreb region of North Africa. The capital and most populous city is Algiers, located in the far north of the country on the Mediterranean coast. With an area of 2,381,741 square kilometres (919,595 sq mi), Algeria is the tenth-largest country in the world, and the largest by area in the African Union and the Arab world. With an estimated population of over 43 million, it is the ninth-most populous country in Africa.
Algeria is bordered to the northeast by Tunisia, to the east by Libya, to the southeast by Niger, to the southwest by Mali, Mauritania, and the Western Saharan territory, to the west by Morocco, and to the north by the Mediterranean Sea. The country has a semi-arid geography, with most of the population living in the fertile north and the Sahara dominating the geography of the south. This arid geography makes the country very vulnerable to climate change.
Pre-1962 Algeria has known many empires and dynasties, including ancient Numidians, Phoenicians, Carthaginians, Romans, Vandals, Byzantines, Umayyads, Abbasids, Idrisid, Aghlabid, Rustamid, Fatimids, Zirid, Hammadids, Almoravids, Almohads, Zayyanids, Spaniards, Ottomans and finally, the French colonial empire. Most of the population is Arab-Berber, practicing Islam and using the official languages of Arabic and Berber. However, French serves as an administrative and education language in some contexts, and Algerian Arabic is the main spoken language.
Algeria has a semi-presidential republic, with local constituencies consisting of 48 provinces and 1,541 communes (counties). Algeria is a regional and middle power. It has the highest human development index of all non-island African countries and one of the largest economies on the continent, based largely on energy exports. Algeria has the 16th largest oil reserves in the world and the second-largest in Africa, while it has the ninth-largest reserves of natural gas. Sonatrach, the national oil company, is the largest company in Africa, supplying large amounts of natural gas to Europe. Algeria has one of the largest militaries in Africa and the largest defence budget. It is a member of the African Union, the Arab League, OPEC, the United Nations, and the Arab Maghreb Union, of which it is a founding member.
2. Democratic Republic of the Congo (2,344,858 km2)
The Democratic Republic of the Congo, also known as Congo-Kinshasa, DR Congo, DRC (the official acronym), or simply the Congo, is a country located in Central Africa. It was formerly called Zaire (1971–1997). It is, by area, the largest country in sub-Saharan Africa, the second-largest in all of Africa (after Algeria), and the 11th-largest in the world. With a population of over 89 million, the Democratic Republic of the Congo is the most populous officially Francophone country in the world, as well as the fourth-most-populous in Africa, and the 16th-most-populous country in the world. Since 2015, the Eastern DR Congo has been the scene of an ongoing military conflict in Kivu.
Centred on the Congo Basin, the territory of the DRC was first inhabited by Central African foragers around 90,000 years ago and was reached by the Bantu expansion about 3,000 years ago. In the west, the Kingdom of Kongo ruled around the mouth of the Congo River from the 14th to 19th centuries. In the centre and east, the kingdoms of Luba and Lunda ruled from the 16th and 17th centuries to the 19th century.
In the 1870s, just before the onset of the Scramble for Africa, European exploration of the Congo Basin was carried out, first led by Henry Morton Stanley under the sponsorship of Leopold II of Belgium. Leopold formally acquired rights to the Congo territory at the Berlin Conference in 1885 and made the land his private property, naming it the Congo Free State. During the Free State, his colonial military unit, the Force Publique, forced the local population to produce rubber. From 1885 to 1908, millions of the Congolese people died as a consequence of disease and exploitation. In 1908, Leopold, despite his initial reluctance, ceded the so-called Free State to Belgium, thus it became known as the Belgian Congo.
Congo achieved independence from Belgium on 30 June 1960 under the name Republic of the Congo. Congolese nationalist Patrice Lumumba was elected the first Prime Minister, while Joseph Kasa-Vubu became the first President. Conflict arose over the administration of the territory, which became known as the Congo Crisis. The provinces of Katanga, under Moïse Tshombe, and South Kasai attempted to secede. After the UN and Western governments refused his requests for aid and Lumumba stated that he was open to any country, including the Soviet Union, for assistance in the crisis, the US and Belgium became wary and oversaw his removal from office by Kasa-Vubu on 5 September and ultimate execution by Belgian-led Katangese troops on 17 January 1961.
On 25 November 1965, Army Chief of Staff Joseph-Désiré Mobutu, who later renamed himself Mobutu Sese Seko, officially came into power through a coup d'état. In 1971, he renamed the country Zaire. The country was run as a dictatorial one-party state, with his Popular Movement of the Revolution as the sole legal party. Mobutu's government received considerable support from the United States, due to its anti-communist stance during the Cold War. By the early 1990s, Mobutu's government began to weaken. Destabilisation in the east resulting from the 1994 Rwandan genocide and disenfranchisement among the eastern Banyamulenge (Congolese Tutsi) population led to a 1996 invasion led by Tutsi FPR-ruled Rwanda, which began the First Congo War.
On 17 May 1997, Laurent-Désiré Kabila, a leader of Tutsi forces from the province of South Kivu, became President after Mobutu fled to Morocco, reverting the country's name to the Democratic Republic of the Congo. Tensions between President Kabila and the Rwandan and Tutsi presence in the country led to the Second Congo War from 1998 to 2003. Ultimately, nine African countries and around twenty armed groups became involved in the war, which resulted in the deaths of 5.4 million people. The two wars devastated the country. President Laurent-Désiré Kabila was assassinated by one of his bodyguards on 16 January 2001 and was succeeded eight days later by his son Joseph, under whom human rights in the country remained poor and included frequent abuses such as forced disappearances, torture, arbitrary imprisonment and restrictions on civil liberties according to NGOs.
The Democratic Republic of the Congo is extremely rich in natural resources but has suffered from political instability, a lack of infrastructure, corruption, and centuries of both commercial and colonial extraction and exploitation with little widespread development. Besides the capital Kinshasa, the two next largest cities, Lubumbashi and Mbuji-Mayi are both mining communities. DR Congo's largest export is raw minerals, with China accepting over 50% of DRC's exports in 2012. In 2016, DR Congo's level of human development was ranked 176th out of 187 countries by the Human Development Index. As of 2018, around 600,000 Congolese have fled to neighbouring countries from conflicts in the centre and east of the DRC. Two million children risk starvation, and the fighting has displaced 4.5 million people. The sovereign state is a member of the United Nations, Non-Aligned Movement, African Union, and COMESA.
3. Sudan (1,861,484 km2)
Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. Bordered by Egypt to the north, Libya to the northwest, Chad to the west, the Central African Republic to the southwest, South Sudan to the south, Ethiopia to the southeast, Eritrea to the east, and the Red Sea to the northeast. Sudan has a population of 43 million (2020 estimate) and occupies 1,886,068 square kilometres (728,215 square miles), making it Africa's third-largest country and also the third-largest in the Arab world. It was the largest country in Africa and the Arab world by area before the 2011 South Sudan's secession.
Sudan's history goes back to the Pharaonic period, witnessing the kingdom of Kerma (c. 2500 BC–1500 BC), the subsequent rule of the Egyptian New Kingdom (c. 1500 BC–1070 BC) and the rise of the kingdom of Kush (c. 785 BC–350 AD), which would in turn control Egypt itself for nearly a century. After the fall of Kush, the Nubians formed the three Christian kingdoms of Nobatia, Makuria and Alodia, with the latter two lasting until around 1500. Between the 14th and 15th centuries much of Sudan was settled by Arab nomads. From the 16th–19th centuries, central and eastern Sudan were dominated by the Funj sultanate, while Darfur ruled the west and the Ottomans the far north. This period saw extensive Islamisation and Arabisation.
From 1820 to 1874 the entirety of Sudan was conquered by the Muhammad Ali dynasty. Between 1881 and 1885, the harsh Egyptian reign was eventually met with a successful revolt led by the self-proclaimed Mahdi Muhammad Ahmad, resulting in the establishment of the Caliphate of Omdurman. This state was eventually toppled in 1898 by the British, who would then govern Sudan together with Egypt.
The 20th century saw the growth of Sudanese nationalism and in 1953 Britain granted Sudan self-government. Independence was proclaimed on 1 January 1956. Since independence, Sudan has been ruled by a series of unstable parliamentary governments and military regimes. Under Jaafar Nimeiry, Sudan instituted Islamic law in 1983. This exacerbated the rift between the Islamic north, the seat of the government and the Animists and Christians in the south. Differences in language, religion, and political power erupted in a civil war between government forces, strongly influenced by the National Islamic Front (NIF), and the southern rebels, whose most influential faction was the Sudan People's Liberation Army (SPLA), eventually concluding in the independence of South Sudan in 2011. Between 1989 and 2019, Sudan experienced a 30-year-long military dictatorship led by Omar al-Bashir accused of widespread human rights abuses including torture, persecution of minorities and notably, ethnic genocide due to its role in the War in Darfur Region that broke out in 2003. Overall, the regime left 300,000–400,000 dead. Protests erupted in late 2018, demanding Bashir's resignation, which resulted in a successful coup d'état on April 11, 2019.
4. Libya (1,759,540 km2)
Libya , officially the State of Libya, is a country in the Maghreb region in North Africa, bordered by 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. The sovereign state is made of three historical regions: Tripolitania, Fezzan and Cyrenaica. With an area of almost 1.8 million square kilometres (700,000 sq mi), Libya is the fourth largest country in Africa, and is the 16th largest country in the world. Libya has the 10th-largest proven oil reserves of any country in the world. The largest city and capital, Tripoli, is located in western Libya and contains over one million of Libya's six million people. The second-largest city is Benghazi, which is located in eastern Libya. The Latin name Libya is based on the name of the region west of the Nile used by the Ancient Greeks and Romans for all of North Africa, and was again adopted during the period of Italian colonization beginning in 1911.
Libya has been inhabited by Berbers since the late Bronze Age as descendants from Iberomaurusian and Capsian cultures. The Phoenicians established trading posts in western Libya, and ancient Greek colonists established city-states in eastern Libya. Libya was variously ruled by Carthaginians, Persians, Egyptians and Greeks before becoming 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. In the 16th century, the Spanish Empire and the Knights of St John 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, which resulted in the Italian occupation of Libya and the establishment of two colonies, Italian Tripolitania and Italian Cyrenaica (1911–1934), later unified in the Italian Libya colony from 1934 to 1947. During the Second World War, Libya was an important area of warfare in the North African Campaign. The Italian population then went into decline.
Libya became independent as a kingdom in 1951. A military coup in 1969 overthrew King Idris I. The "bloodless" coup leader Muammar Gaddafi ruled the country from 1969 and the Libyan Cultural Revolution in 1973 until he was overthrown and killed in the 2011 Libyan Civil War. Two authorities initially claimed to govern Libya: the House of Representatives in Tobruk and the 2014 General National Congress (GNC) in Tripoli, which considered itself the continuation of the General National Congress, elected in 2012. After UN-led peace talks between the Tobruk and Tripoli governments, a unified interim UN-backed Government of National Accord was established in 2015, and the GNC disbanded to support it. Since then, a second civil war has broken out, with parts of Libya split between the Tobruk and Tripoli-based governments, as well as various tribal and Islamist militias. As of July 2017, talks are still ongoing between the GNA and the Tobruk-based authorities to end the strife and unify the divided establishments of the state, including the Libyan National Army and the Central Bank of Libya.
Libya is a member of the United Nations (since 1955), the Non-Aligned Movement, the Arab League, the OIC and OPEC. The country's official religion is Islam, with 96.6% of the Libyan population being Sunni Muslims.
5. Chad (1,284,000 km2)
Chad, officially known as the Republic of Chad, is a landlocked country in north-central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the south-west, Nigeria to the southwest (at Lake Chad), and Niger to the west.
Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the largest wetland in Chad and the second-largest in Africa. The capital N'Djamena is the largest city. Chad's official languages are Arabic and French. Chad is home to over 200 different ethnic and linguistic groups. The most popular religion of Chad is Islam (at 55%), followed by Christianity (at 40%).
Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbers. By the end of the 1st millennium AD, a series of states and empires had risen and fallen in Chad's Sahelian strip, each focused on controlling the trans-Saharan trade routes that passed through the region.
France conquered the territory by 1920 and incorporated it as part of French Equatorial Africa. In 1960, Chad obtained independence under the leadership of François Tombalbaye. Resentment towards his policies in the Muslim north culminated in the eruption of a long-lasting civil war in 1965. In 1979 the rebels conquered the capital and put an end to the South's hegemony. But, the rebel commanders fought amongst themselves until Hissène Habré defeated his rivals. Chadian–Libyan conflict erupted in 1978 by the Libyan invasion which stopped in 1987 with a French military intervention (Operation Épervier). Hissène Habré was overthrown in turn in 1990 by his general Idriss Déby. With French support, a modernization of the Chadian armed forces was initiated in 1991. Since 2003 the Darfur crisis in Sudan has spilt over the border and destabilised the nation. Poor already, the nation and people struggled to accommodate the hundreds of thousands of Sudanese refugees who live in and around camps in eastern Chad.
While many political parties are active, power lies firmly in the hands of President Déby and his political party, the Patriotic Salvation Movement. Chad remains plagued by political violence and recurrent attempted coups d'état. Chad is one of the poorest and most corrupt countries in the world; most inhabitants live in poverty as subsistence herders and farmers. Since 2003 crude oil has become the country's primary source of export earnings, superseding the traditional cotton industry. Chad has a poor human rights record, with frequent abuses such as arbitrary imprisonment, extrajudicial killings, and limits on civil liberties by both security forces and armed militias.
