Originally calledFort-Lamy, it was founded in 1900 by the French during their colonization of Central Africa. The city was renamed N'Djamena in 1973, reflecting its local Chadian heritage. Throughout its history, N'Djamena has grown from a smalltrading hub into thepolitical andeconomic center of Chad, playing a vital role in the country's development. Its strategic location near the borders of Cameroon and Nigeria has historically made it an importantcrossroads for trade and cultural exchange in the region.[5]
N'Djamena is situated on theChari River in the southwestern part of Chad, near Lake Chad. The city lies within a semi-arid region characterized by ahot climate with a distinct dry season. Its location on the river provides vitalwater resources foragriculture and daily life, although the surrounding landscape is largely flat and arid. The city's proximity to Lake Chad also influences its climate and ecology, making it an important area for both local agriculture and regional trade. The geography of N'Djamena has shaped its development as a keyurban center in Chad,[6] with its strategic position contributing to its historical and economic significance.
The name "N'Djamena" is derived from the Arabic term "Niǧāmīnā" (نجامينا), meaning "place of rest" or "place of peace".[8]
Before its renaming in 1973, the city was known as Fort-Lamy, named after French army officer Amédée-François Lamy. The change to N'Djamena was part of a broader movement to replace colonial names with indigenous ones, reflecting the local Arabic heritage and cultural identity.[b][8][9]
The name itself reflects the blending of Arabic linguistic influence and local Chadian culture, illustrating the region’s complex historical and cultural interactions.[9]
N'Djamena was founded asFort-Lamy by French commanderÉmile Gentil on 29 May 1900, and named afterAmédée-François Lamy, an army officer who had been killed in theBattle of Kousséri about a month earlier.[10][11] It was merely a colonial outpost in its early days, and until the 1920s, the city was entirely under French military rule.[12] It has since expanded into a major trading city and became the capital of the region and nation.
During theSecond World War, the French relied upon the city's airport to move troops and supplies.[13] On 21 January 1942, a loneGermanHeinkel He 111 of theSonderkommando Blaich successfully bombed the airfield at Fort-Lamy, destroying oil supplies and ten aircraft.[14]
The city was partly destroyed during theChadian Civil War, in 1979 and again in 1980. In these years, almost all of the population fled the town, seeking refuge on the opposite bank of theChari River in Cameroon, next to the city ofKousséri. The residents did not return until 1981–82, after the end of the clashes. Until 1984, facilities and services were subject to strict rationing, and schools remained closed.[18]
The period of turmoil in the city was started by the abortive coup attempted by the northerner Prime MinisterHissène Habré against the southerner PresidentFélix Malloum: while Malloum and the national army loyal to him were defeated, the intervention in the battle of other northern factions rival to that of Habré complicated the situation. A temporary truce was reached in 1979 through international mediation, establishing the warlordGoukouni Oueddei as head of a government of national unity with his rival Habré as Defense Minister. The intense rivalry between Goukouni and Habré caused the eruption of new clashes in the city in 1980; N'Djamena found itself divided into sectors controlled by the various warlords. The tug-of-war reached a conclusion after many months only when Goukouni asked for the intervention of the Libyans, whose tanks overwhelmed Habré's defenses in the capital.[19]
Following differences between Goukouni andMuammar Gaddafi and international disapproval of Libyan intervention, the Libyan troops left the capital and Chad in 1981. This opened the door to Habré, who marched on N'Djamena, occupying the city with little resistance in 1982 and installing himself as the new president.[21] He was eventually dislodged in a similar fashion in 1990 by a former general of his,Idriss Déby.[citation needed]
The city had only 9,976 inhabitants in 1937, but a decade later, in 1947, the population had almost doubled to 18,435. In 1968, after independence, the population reached 126,483. In 1993, it surpassed half a million with 529,555. A good deal of this growth has been due to refugees fleeing into N'Djamena for security, although many people fled N'Djamena, also depending on the political situation.[13] The city surpassed the million mark in population by the early 2010s.
The city is formally divided into 10 administrative districts, which are loosely grouped into three distinct areas of the city. There is an old colonial core along the Chari River which houses much of the administrative institutions that fulfill N'Djamena's role as national capital. To the north and east of the core, there is newer construction, referred to by some residents as the "African city", with mixed-class residents and much of the city's trade. Most of the city's current growth is in the third area, even further east, with limited formal infrastructure.[12]
N'Djamena has ahot semi-arid climate (KöppenBSh) with a shortwet season and a lengthydry season. Despite the fact that the city receives on average approximately 510 mm (20 in) of rainfall annually, due to the area's very highevapotranspiration, N'Djamena still falls into the semi-arid climate category.[citation needed] The wet season lasts from June to September, with the heaviest rain occurring in August. The dry season essentially covers the remaining eight months.[25] Based on annual temperatures, N'Djamena is one of the hottest major cities on the planet. In only one month of the year (August) do average monthly high temperatures fail to cross the 32 °C (90 °F) mark. The city's highest temperatures are usually seen between March and May, just before the onset of the heavier rains.

N'Djamena's climate is affected by the collision of two large air masses over Chad, one continental and one maritime, whose interactions can produce unpredictable weather.[25] According to the World Air Quality Report 2024, N'Djamena is one of the world's 20 most polluted cities.[31] The water in the Chara River also contains high levels of someheavy metal contaminants, increasing downstream of the city and during the dry season.[25]
N'Djamena's primary economic source is agricultural work. About 80% of the population within N'Djamena works within farming-based industries, including cultivation of crops and growinglivestock. The economy in N'Djamena is therefore almost totally reliant on good weather, making the economy struggle in years with low rainfall. N'Djamena receives financial aid from theWorld Bank, as well as theAfrican Development Bank. There is a high demand for skilled laborers within N'Djamena to work for oil and gas sectors, as well as laborers for foreignnon-governmental organizations,medical services, and English teaching. Residents of N'Djamena are liable to pay tax up to a maximum amount of 60% of all net income.[32]

Attractions in the city include theChad National Museum, the Al-Mouna Cultural Center,Our Lady of Peace Cathedral, and severalmosques. Within the Chad National Museum, one can view the partial skull of aSahelanthropus, called by locals as "Toumaï".[33] This skull was discovered in the northern part of Chad and is considered to be from one of the earliest human ancestors.[34] Views ofsunset across the Chari River can also be spectacular. N'Djamena was namedCapital of Islamic Culture in 2009.[35]
In N'Djamena, education can be thought of as a luxury even though it is compulsory and free and has been since Chad's independence in 1960.[36] Not more than forty percent of elementary age children in Chad have an opportunity to attend classes and with N'Djamena's poor state stability it is even harder for children to get an education. After progressing through elementary school, some students go on to a university.[37] N'Djamena has two universities: theUniversity of N'Djamena with French as the language of instruction, built in 1971;[38] andKing Faisal University - Chad with Arabic as the language of instruction,[39] built in 1991. Secondary schools include the long established LycéeFélix Éboué and Lycée technique commercial, theLycée Montaigne de N'Djamena (French international school). Secondary school within Chad is mandatory, however only 68% of students over the age of 12 attend school. Of that 68%, 70% of these students attend school in N'Djamena. Many of the students in international schools are children of executives, diplomats, and non-governmental organization employees.[40][unreliable source?]
N'Djamena is the home of theNational Assembly of Chad, along with many political organisations and parties, and every national ministry. The Supreme Court and Court of Appeal are also in N'Djamena, along with every major embassy in Chad, including the French and US embassies.[42] It is sometimes considered within theregion ofChari-Baguirmi, although separate.[43]
The city has norailway links. However, railways have been proposed.[47] In 2011, Chad signed a contract with a Chinese civil engineering group to build a railway to eventually connect N'Djamena to Sudan and Cameroon, as well as other Chadian cities.[48] In 2017, a further feasibility study was funded, but as of 2025[update], no railroads have been built.[49]
