Chad 24°E. Chad is bounded to the north by Libya, to the east by Sudan, to the west by Niger, Nigeria and Cameroon, and to the south by the Central African Republic. The country's capital is from the nearest seaport, Douala, Cameroon. Because of this distance from the sea and the country's largely desert climate, Chad is sometimes referred to as the "Dead Heart of Africa". The dominant physical structure is a wide basin bounded to the north and east by the Ennedi Plateau and Tibesti Mountains, which include Emi Koussi, a dormant volcano that reaches above sea level.

Niger far east as western Niger. The Kanem-Bornu Empire was an empire that existed in modern-day Chad, Nigeria, Cameroon, Niger and Libya. The empire first existed and prospered as the Kanem Empire as early as the 9th century and later as the Kingdom of Bornu until 1900. In the 19th century, contact with Europe began with the first European explorers—notably Monteil (French) and Barth (German)—to travel to Niger. Following the 1885 Berlin conference during which colonial powers outlined the division of Africa into colonial spheres, French military efforts to conquer existing African states were intensified in all French colonies including Niger.
