History
The north was a land of river traders and forest peoples long before colonisation. The Teke kingdom ruled the plateaus in the south of the region, the Mbochi and related peoples lived along the Alima and the other tributaries of the Congo, and the Aka and other hunter-gatherer groups moved through the forests of the Sangha and the Likouala, trading forest products with farming neighbours.
Pierre Savorgnan de Brazza reached the Alima in 1878 and returned in 1880 to sign the treaty with the Teke ruler, the Makoko, that gave France its claim to the region. France later handed much of the north to concession companies that extracted rubber and ivory with forced labour; reports of abuses led to a government inquiry headed by Brazza in 1905. Posts such as Fort-Rousset, now Owando, and Ouesso became the administrative centres of a region that remained thinly settled.
After independence the north supplied most of the country's rulers: Marien Ngouabi and Joachim Yhombi-Opango came from the Cuvette, and Denis Sassou Nguesso is from the Oyo area, which has since received major state investment. Odzala was first protected in 1935, Nouabalé-Ndoki became a national park in 1993, and in the early 2000s Ebola outbreaks killed large numbers of gorillas in and around Odzala. Since 2010 the conservation organisation African Parks has managed Odzala-Kokoua with the government.
