The Republic of the Congo, also known as Congo-Brazzaville, the Congo Republic or simply Congo, is a country located on the western coast of Central Africa to the west of the Congo River. It is bordered to the west by Gabon, to the northwest by Cameroon, to the northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to the south by the Angolan exclave of Cabinda, and to the southwest by the Atlantic Ocean.
The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. From the 13th century, the present-day territory was dominated by a confederation led by Vungu which included Kakongo and Ngoyo. The Tio Kingdom emerged in the 14th century, and Loango in the 16th century. In the late 19th century France colonised the region and incorporated it into French Equatorial Africa. The Republic of the Congo was established on 28 November 1958 and gained independence from France in 1960. It was a Marxist–Leninist state from 1969 to 1992, under the name People's Republic of the Congo (PRC). After the introduction of multi-party elections in 1992, the democratically elected government was overthrown during the civil war, after which Denis Sassou Nguesso, who had previously served as president from 1979 to 1992, returned to office in 1997. He has remained president since then.
The Republic of the Congo is a member of the African Union, the United Nations, La Francophonie, the Economic Community of Central African States, and the Non-Aligned Movement. It is the fourth-largest oil producer in the Gulf of Guinea, providing the country a degree of prosperity, with political and economic instability in some areas and unequal distribution of oil revenue nationwide. Its economy is dependent on the oil sector and economic growth slowed after the post-2015 drop in oil prices.
Christianity is the most widely professed faith in the country. According to the 2024 rendition of the World Happiness Report, the Republic of the Congo is ranked 89th among 140 nations.

Etymology
It is named after the Congo River whose name is derived from Kongo, a Bantu kingdom that occupied its mouth around the time the Portuguese first arrived in 1483 or 1484. The kingdom's name derived from its people, the Bakongo, an endonym said to mean "hunters" (Kongo: mukongo, nkongo).
During the period when France colonised it, it was known as the French Congo or Middle Congo. The Republic of the Congo, or simply the Congo, is a distinct country from the Democratic Republic of the Congo, also known as the DR Congo. Brazzaville's name derives from the colony's founder, Pierre Savorgnan de Brazzà, an Italian nobleman whose title referred to the town of Brazzacco, in the Italian comune of Moruzzo in Friuli-Venezia Giulia, whose name derived from the Latin Brattius or Braccius, both meaning literally "arm".
History
Bantu-speaking peoples, who founded tribes during the Bantu expansions, mostly displaced and absorbed the earlier inhabitants of the region, the Pygmy people, about 1500 BC. The Bakongo, a Bantu ethnic group that occupied parts of what later became Angola, Gabon, and the Democratic Republic of the Congo, formed the basis for ethnic affinities and rivalries among those countries.
By the 13th century, there were three main federations of states in the western Congo Basin. In the east were the Seven Kingdoms of Kongo dia Nlaza, considered to be the oldest and most powerful, which likely included Nsundi, Mbata, Mpangu, and possibly Kundi and Okanga. South of these was Mpemba which stretched from modern-day Angola to the Congo River. It included various kingdoms such as Mpemba Kasi and Vunda. To its west across the Congo River was a confederation of three small states; Vungu (its leader), Kakongo, and Ngoyo. Some Bantu kingdoms—including those of the Kongo, the Tio, and Loango—built trade links leading into the Congo Basin. The Tio Kingdom formed in the 14th century; the association of kingship with smithing is believed to have originated among the Tio before spreading to the kingdoms of Loango and Kongo.
The Portuguese explorer Diogo Cão reached the mouth of the Congo in 1484. Commercial relationships grew between the inland Bantu kingdoms and European merchants who traded in commodities, manufactured goods, and people captured and enslaved in the hinterlands. After centuries as a central hub for transatlantic trade, direct European colonization of the Congo River delta began in the 19th century, subsequently eroding the power of the Bantu societies in the region.
The area north of the Congo River came under French sovereignty in 1880 as a result of Pierre de Brazza's treaty with Tio King Iloo I. After the death of Iloo, his widow Queen Ngalifourou upheld the terms of the treaty and became an ally to the colonizers. This Congo Colony became known first as French Congo, then as Middle Congo in 1903.
In 1908, France organized French Equatorial Africa (AEF), comprising the Middle Congo, Gabon, Chad, and Oubangui-Chari (which later became the Central African Republic). The French designated Brazzaville as the federal capital. Economic development during the first 50 years of colonial rule in Congo centered on natural resource extraction. Construction of the Congo–Ocean Railway following World War I has been estimated to have cost at least 14,000 lives.
Geography
Natural landscapes range from the savanna plains in the North Niari flooded forests, to the Congo River, to the rugged mountains and forests of Mayombe, and 170 km of beaches along the Atlantic coast.
Congo is located in the central-western part of sub-Saharan Africa, along the Equator, lying between latitudes 4°N and 5°S, and longitudes 11° and 19°E. To the south and east of it is the Democratic Republic of the Congo. It is bounded by Gabon to the west, Cameroon and the Central African Republic to the north, and Cabinda (Angola) to the southwest. It has a coast on the Atlantic Ocean.
The southwest is a coastal plain for which the primary drainage is the Kouilou-Niari River; the interior of the country consists of a central plateau between 2 basins to the south and north. Forests are under increasing exploitation pressure. Congo had a 2018 Forest Landscape Integrity Index mean score of 8.89/10, ranking it 12th globally out of 172 countries.
Congo lies within four terrestrial ecoregions: Atlantic Equatorial coastal forests, Northwestern Congolian lowland forests, Western Congolian swamp forests, and Western Congolian forest–savanna mosaic. Since the country is located on the Equator, the climate is more consistent year-round, with the average day temperature a humid 24 °C (75 °F) and nights generally between 16 °C (61 °F) and 21 °C (70 °F). The average yearly rainfall ranges from 1,100 millimetres (43 in) in the Niari Valley in the south to over 2,000 millimetres (79 in) in central parts. The dry season is from June to August, while in the majority of the country, the wet season has 2 rainfall maxima: 1 in March–May and another in September–November.
In 2006–07, researchers from the Wildlife Conservation Society studied gorillas in "heavily forested" regions centered on the Ouesso District of the Sangha Region. They suggest a population on the order of 125,000 western lowland gorillas whose isolation from humans has been mostly preserved by "inhospitable" swamps.
Government and politics
The government of the republic is a semi-presidential system with an elected president who appoints the Council of Ministers, or Cabinet. The council, including the prime minister, is selected from the elected representatives in Parliament. Since the 1990s, the country has had a multi-party political system that is dominated by President Denis Sassou Nguesso. Sassou Nguesso is backed by his own Congolese Labour Party (French: Parti Congolais du Travail ) as well as a range of smaller parties.
Sassou's regime has seen corruption revelations, with attempts to censor them. One French investigation found over 110 bank accounts and dozens of "lavish properties" in France. Sassou denounced embezzlement investigations as "racist" and "colonial". Denis Christel Sassou-Nguesso, son of Denis Sassou Nguesso, has been named in association with the Panama Papers.
On 27 March 2015, Sassou Nguesso announced that his government would hold a referendum on changing the country's 2002 constitution to allow him to run for a third consecutive term in office. On 25 October, the government held a referendum on allowing Sassou Nguesso to run in the next election. The government claimed that the proposal was approved by 92% of voters, with 72% of eligible voters participating. The opposition who boycotted the referendum said that the government's statistics were false and the vote was a fake one. The election raised questions and was accompanied by civil unrest and police shootings of protesters; at least 18 people were killed by security forces during opposition rallies leading up to the referendum held in October.
Administrative divisions
The republic has been divided into 15 departments since the adoption of the corresponding laws in October 2024. Departments are divided into communes and districts.
These are as follows:
Human rights
Some Pygmies belong from birth to Bantus in a relationship some refer to as slavery. The Congolese Human Rights Observatory says that the Pygmies are treated as property in the same way as pets. On 30 December 2010, the Congolese parliament adopted a law to promote and protect the rights of indigenous peoples. This law is "the first" of its kind in Africa.
Economy
The economy is a mixture of village agriculture and handicrafts, an industrial sector based mainly on petroleum, support services, and a government characterized by budget problems and "overstaffing". Petroleum extraction has supplanted forestry as the mainstay of the economy. In 2008, the oil sector accounted for 65% of the GDP, 85% of government revenue, and 92% of exports. The country has untapped mineral wealth.
In the 1980s, rising oil revenues enabled the government to finance larger-scale development projects. GDP grew an average of 5% annually. The government has mortgaged a portion of its petroleum earnings, contributing to a "shortage of revenues". On 12 January 1994, the devaluation of Franc Zone currencies by 50% resulted in an inflation of 46% in 1994, and inflation has subsided since.
Between 1994 and 1996, the economy underwent a difficult transition. The Congo took a number of measures to liberalize its economy, including reforming the tax, investment, labor, timber, and hydrocarbon codes. In 2002–03, Congo privatized banks, telecommunications, and transportation monopolies, to help improve an unreliable infrastructure. By the end of 1996 Congo had made progress in various areas targeted for reform. It made great strides toward macroeconomic stabilization through improving public finances and restructuring external debt. This change was accompanied by improvements in the structure of expenditures, with a reduction in personnel expenditures. Before June 1997, Congo and the United States ratified a bilateral investment treaty designed to facilitate and protect foreign investment. The country also adopted a new investment code intended to attract foreign capital. Despite these success, Congo's investment climate has challenges, offering few meaningful incentives for new investors.
Economic reform efforts continued with the support of international organizations, including the World Bank and the International Monetary Fund. The reform program came to a halt in June 1997 when civil war erupted. When Sassou Nguesso returned to power in October 1997, he publicly expressed interest in moving forward on economic reforms and privatization and in renewing cooperation with international financial institutions. Economic progress was "badly hurt" by slumping oil prices and the resumption of armed conflict in December 1998, which "worsened" the republic's budget deficit.
Demographics
According to the official 2023 census, the population of the Congo numbers 6,142,180 people, up from 3,697,490 recorded by the 2007 census. Its population is concentrated in the southwestern portion, leaving the areas of tropical jungle in the north virtually uninhabited. 70% of its total population lives in urban areas, namely in Brazzaville, Pointe-Noire, or one of the cities or villages lining the 534-kilometre (332 mi), railway which connects the two cities. In rural areas, industrial and commercial activity has declined in some years, leaving rural economies dependent on the government for support and subsistence.
Before the 1997 war, about 9,000 Europeans and other non-Africans lived in Congo, most of whom were French; a fraction of this number remains. Around 300 American immigrants reside in the Congo.
The government 2025 demographic and health survey (DHS) reported the total fertility rate had declined to 3.5 children born per woman, with a rate of 3.0 in urban areas and 5.3 in rural areas. The 2011–12 DHS found the TFR was 5.1 children born per woman, with 4.5 in urban areas and 6.5 in rural areas.
Languages
French is the official language of the Republic of the Congo. Kituba and Lingala are recognized as national languages. In addition, Ethnologue recognizes 62 spoken languages in the country. The Kongo are the largest ethnic group and form roughly half of the population. The most significant subgroups of the Kongo are Laari, in Brazzaville and Pool regions, and the Vili, around Pointe-Noire and along the Atlantic coast. The second largest group is the Teke, who live to the north of Brazzaville, with 16.9% of the population. Mbochi live in the north, east and in Brazzaville and form 13.1% of the population. Pygmies make up 2% of Congo's population.
Religion
According to CIA World Factbook, the people of the Republic of the Congo are largely a mix of Catholics (33.1%), adherents of Awakening Churches and Christian Revivalism (22.3%), and other Protestants (19.9%) as of 2007. Followers of Islam make up 1.6%; this is primarily due to an influx of foreign workers into the urban centers.
Education
Public expenditure of the GDP was less in 2002–05 than in 1991. Public education is theoretically free and mandatory for under-16-year-olds but in practice educational expenses must be borne by parents. In 2005 the net primary enrollment rate was 44%, a drop from 79% in 1991. The investment in education has significantly dropped in recent years, leading to a dip in quality. In 2018, the school completion rate was 66% for girls and 64% for boys. Although the government has made attempts to provide Vocational training and tertiary education, they remain poor and inaccessible to most young adults in the country.
Health
Public expenditure health was at 8.9% of the GDP in 2004 whereas private expenditure was at 1.3%.
As of 2012, the HIV/AIDS prevalence was at 2.8% among 15- to 49-year-olds. Health expenditure was at US$30 per capita in 2004. A proportion of the population is undernourished, and malnutrition is a problem in Congo. There were 20 physicians per 100,000 persons in the 2000s (decade).
As of 2010, the maternal mortality rate was 560 deaths/100,000 live births, and the infant mortality rate was 59.34 deaths/1,000 live births. Female genital mutilation (FGM) is confined to limited geographic areas.
Culture
Media
Rural Congolese often receive their news via state-run radio; broadcast media is the main source of news for the majority of Congolese. Government-owned and private media are usually pro-government. Programs are broadcast in a variety of languages. Print media is often circulated in Brazzaville and Pointe-Noire. Important news papers include Le Choc, Les Echos du Congo, L'Observateur, and Le Semaine Africaine.
Sports
The most popular sports in the country are basketball, football, rugby union, volleyball, and tennis. Basketball and football are extremely popular amongst the Congolese youth.
