Chad

In 2001 a French-led team working in the Djurab desert of northern Chad uncovered a remarkably complete cranium, nicknamed Toumaï, belonging to a new species named Sahelanthropus tchadensis. Dated to roughly seven million years, it is among the oldest known members of the human lineage, suggesting that key chapters of human evolution unfolded far from the East African Rift, in what is now one of the planet's harshest deserts.

Far later, from around the sixth century BCE, the Sao civilisation flourished along the lower Chari River and the southern shores of Lake Chad, across present-day Chad, Cameroon and Nigeria. The Sao left no writing but are known through hundreds of archaeological sites and their distinctive terracotta and bronze figures of humans and animals, together with funerary urns, jewellery and decorated pottery.

The Sao endured into the medieval period before being absorbed by the rising states of the Lake Chad basin; peoples such as the Kotoko, Buduma and Kanembu trace descent from them. Their fortified mound settlements mark the basin as a long-inhabited centre of population, trade and craft, the seedbed from which Chad's later empires grew.

   Rise of the Sao culture

   The Sao settled the lower Chari and southern Lake Chad, producing celebrated terracotta and bronze figures across more than 350 known sites before being absorbed by later states.

   Discovery of Toumaï

   A team led by Michel Brunet recovered the cranium of Sahelanthropus tchadensis at the Toros-Menalla (TM 266) site in the Djurab desert; the species was announced in 2002 and dated to about seven million years.

From about the eighth century the empire of Kanem rose on the north-eastern side of Lake Chad, controlling the southern end of the caravan road to Tripoli. Its wealth came from the trans-Saharan trade: horses, salt and manufactured goods moved south, while enslaved people captured in raids to the south, together with ivory and other goods, moved north. In the eleventh century the ruling Duguwa gave way to the Sayfawa dynasty, traditionally founded by Mai Hummay, whose conversion made Islam the religion of the court.

Kanem reached its zenith in the thirteenth century under Mai Dunama Dibalemi (reigned c. 1210–1248), who commanded a large cavalry and extended influence from the Fezzan in modern Libya to the savanna south of the lake. Internal strife and pressure from the Bulala forced the Sayfawa to abandon their capital Njimi around the 1380s and relocate west of Lake Chad to Bornu, where they refounded the state and built a new capital at Ngazargamu.

The reconstituted empire of Kanem-Bornu peaked again in the late sixteenth century under Mai Idris Alooma, who imported firearms and Ottoman military advisers and pushed Islamic law. From the early nineteenth century the empire was shaken by the Fulani jihad and was effectively rescued and then ruled by the scholar-soldier Muhammad al-Kanemi; the ancient line of mais was formally ended in 1846, and the al-Kanemi shehus governed the rump of Bornu thereafter.

Figures of the era

Beyond Bornu, two Islamic sultanates dominated the region between Lake Chad and Darfur. Baguirmi, south-east of the lake, emerged in the sixteenth century and adopted Islam, while Wadai (Ouaddaï) arose to its north-east. Both were intermittently tributary to Bornu yet developed their own courts, armies and commerce, fighting and trading with one another and with their larger neighbour.

Wadai was founded around 1635 when Abd al-Karim led a Muslim revolt that overthrew the ruling Tunjur and established a new sultanate centred eventually on Abéché. From the early nineteenth century, under rulers such as Muhammad Sabun, Wadai expanded and grew wealthy by commanding caravan routes that linked Abéché northward to Benghazi on the Mediterranean and eastward toward Darfur and the Nile.

These states were deeply tied to the trans-Saharan economy. Salt, natron, kola nuts, ivory, cloth and especially enslaved people moved along their routes; Baguirmi and Wadai both raided southern peoples for captives, and Wadai is often described as the last of the great Sudanic empires to control the Saharan slave trade. That commerce shaped the social order of the Chadian basin until European conquest dismantled it.

In the late nineteenth century the warlord Rabih az-Zubayr, leading a well-armed and disciplined private army out of the Sudan, swept across the region. Between 1892 and 1894 he conquered Bornu and made himself master of much of the Lake Chad basin, ruling it as a militarised state and clashing with Baguirmi and other powers just as France was advancing toward the lake from three directions.

French columns converging from Congo, Niger and Algeria met near the Chari River, and on 22 April 1900 they defeated and killed Rabih at the Battle of Kousséri; the French commander, Major Amédée-François Lamy, also died in the fighting. The victory opened the basin to French control. France subdued the sultanates over the following years and constituted Chad as a colonial territory, attaching it to French Equatorial Africa in 1910.

Colonial rule was thin and uneven: the cotton-growing south was developed and administered far more closely than the vast Muslim north and the Saharan Borkou-Ennedi-Tibesti, a neglect that hardened regional divisions. In 1946 Chad became an overseas territory of the French Republic; an autonomous republic within the French Community was proclaimed in 1958, leading toward full sovereignty.

   [15]

Figures of the era

Chad became independent on 11 August 1960 under François (later Ngarta) Tombalbaye, a southerner whose increasingly authoritarian, southern-dominated rule alienated the largely Muslim north and centre. In 1966 the rebel front FROLINAT took up arms, beginning a civil war that would define the country. Tombalbaye was killed in a military coup in 1975, which brought General Félix Malloum to power without ending the fighting.

Through the late 1970s FROLINAT's factions, several backed by Libya, contested the country; rebels reached the capital and in 1979 Goukouni Oueddei and Hissène Habré joined a fragile transitional government that soon collapsed into renewed war between them. Libya, which occupied the Aouzou Strip in the north, intervened repeatedly on Goukouni's side. In 1982 Habré seized N'Djamena and the presidency.

Habré consolidated a harsh one-party state while fighting Libya. In 1987, in the so-called Toyota War, his mobile forces inflicted heavy defeats on the Libyan army and drove it back toward the Aouzou Strip. His regime, however, became notorious for political killings and torture: a later truth commission and court would attribute tens of thousands of deaths to it. In December 1990 Habré was overthrown by his former army commander, Idriss Déby.

Figures of the era

Idriss Déby took power in December 1990 and ruled Chad for thirty years. He introduced a multiparty constitution in 1996 and won repeated elections widely criticised as flawed, while surviving rebellions that twice reached the capital. From the early 2000s an oil pipeline gave the state new revenues, and Déby positioned Chad's army as a key Western partner against jihadist groups in the Sahel and around Lake Chad.

The crimes of the earlier Habré regime were eventually answered in court. In 2016 the Extraordinary African Chambers in Senegal convicted Hissène Habré of crimes against humanity, war crimes and torture, sentencing him to life imprisonment; the verdict, upheld on appeal in 2017, was the first time a former head of state was convicted of such crimes in another country's courts under universal jurisdiction. The earlier Aouzou dispute had already been settled when the International Court of Justice awarded the strip to Chad in 1994.

Idriss Déby was killed in April 2021 while visiting troops fighting a rebel incursion, days after claiming a sixth term. A military council immediately installed his son, General Mahamat Idriss Déby, as transitional head of state, a step many regarded as an unconstitutional dynastic succession. Mahamat Déby consolidated power and was declared winner of a presidential election in 2024, extending the family's hold on Chad.
