Ndjamena Map

• N'Djamena features a semi-arid climate with a short wet season and a lengthy dry season. Despite the fact that the city receives on average approximately 750 mm of rain annually, due to the area’s very high evapotranspiration, N'Djamena still falls under the semi-arid climate category. The wet season covers from June to September, with the heaviest precipitation occurring in August. The dry season essentially covers the remaining eight months. Based on annual temperatures, N'Djamena is one of the hottest major cities on the planet. 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 June, just before the onset of the heavier rains. However outside of the warmest months of the year, nights in N'Djamena are generally tolerable.

• N'Djamena is located at 12°6'47" N, 15°2'57" E, on the confluence of the Chari and Logone rivers.While primarily an administrative center, the city includes the Nassara Strip commercial centre and residential areas such as Mbololo, Chagoua, Paris Congo and Moursal. The main commercial avenue of the city is the Avenue Charles de Gaulle.

• The city is the eastern terminus of the Trans-Sahelian Highway, and is linked to East Africa by the Ndjamena-Djibouti Highway. The Tripoli-Cape Town Highway also passes through N'Djamena, making it a key Central African location in the Trans-African Highway network. Ndjamena is linked by road bridge to Kousseri in Cameroon.N'Djamena International Airport (IATA code NDJ) is located on the outskirts of the city.Historically, N'Djamena's main link to the exterior was by river boat up the Chari and Logone rivers but these now carry little trade.The city has no railway links, however railways are proposed in the AfricaRail project.

• N'Djamena was founded as Fort-Lamy by French commander Émile Gentil on May 29, 1900, and named after Amédée-François Lamy, an army officer who had been killed in the Battle of Kousséri a few days earlier. It was a major trading city and became the capital of the region and nation.

• During the Second World War, the French relied heavily upon the airport to move troops and supplies. On 21 January 1942, a lone German He 111 of the Sonderkommando Blaich successfully bombed the airfield at Fort Lamy, destroying oil supplies and ten aircraft. Fort Lamy received its first bank branch in 1950, when the Bank of West Africa (BAO) opened a branch there.

• On April 6, 1973, the President François Tombalbaye changed its name to N'Djamena (taken from the Arab name of a nearby village, Niǧāmīnā, meaning "place of rest") as part of his authenticité program of Africanization. The city was occupied by Libya during the 1980-1 Libyian intervention as part of the Chadian–Libyan conflict, and the associated Transitional Government of National Unity.

• The city was partly destroyed during the Chadian Civil War, in 1979 and again in 1980. In these years almost all of the population fled the town, searching for refuge on the opposite bank of the Chari River, in Cameroon next to the city of Kousseri. The residents did not return until 1981-82 after the end of the clashes. Up until 1984, facilities and services were subject to strict rationing, and the schools remained closed.

• The period of turmoil in the city was started by the abortive coup attempted by the northerner Prime Minister Hissène Habré against the southerner President General Félix 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 warlord Goukouni Oueddei as head of a government of national unity with his rival Habré as Defense Minister. The intense rivality between Goukouni and Habré caused the eruption of new clashes in the city in 1980; N'Djamena found itself divided in sectors controlled by the various warlords. The tug-of-war reached a conclusion after many monthes only when Goukouni asked for the intervention of the Libyans, whose tanks overwhelmed Habré's defenses in the capital.

• Following differences between Goukouni and Qaddafi 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 with little resistance the city in 1982 and placing himself as new President. He was eventually dislodged in a similar fashion in 1990 by a former general of his, Idriss Déby, the current head of state of Chad.

• The city had only 9,976 inhabitants in 1937, but a decade later, in 1947, the population had almost doubled at 18,435. After independence in 1968 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.

• On April 13, 2006, a rebel United Front for Democratic Change attack on the city was defeated in the Battle of N'Djamena.

• The city was once again attacked on February 2, 2008, by UFDD and RFC rebels. (See Battle of N'Djamena (2008))
