Adamawa Region in the context of "Adamawa Emirate"

The East Region (French: Région de l'Est) occupies the southeastern portion of the Republic of Cameroon. It is bordered to the east by the Central African Republic, to the south by Congo, to the north by the Adamawa Region, and to the west by the Centre and South Regions. With 109,002 km of territory, it is the largest region in the nation as well as the most sparsely populated. Historically, the peoples of the East have been settled in Cameroonian territory for longer than any other of the country's many ethnic groups, the first inhabitants being the Baka (or Babinga) pygmies.

The East Region has very little industry, its main commerce consisting of logging, timber, and mining. Instead, the bulk of its inhabitants are subsistence farmers. The region is thus of little political import and is often ignored by Cameroonian politicians. This coupled with the low level of development in the province have led to its being dubbed "the forgotten province".

The West Region (French: Région de l'Ouest) is 14,000 km of territory located in the central-western portion of the Republic of Cameroon. It borders the Northwest Region to the northwest, the Adamawa Region to the northeast, the Centre Region to the southeast, the Littoral Region to the southwest, and the Southwest Region to the west. The West Region is the smallest of Cameroon's ten regions in area, yet it has the highest population density.

As home to the enterprising Bamum and Bamileke kingdoms, the West is an economic bright spot and one of Cameroon's more developed regions. This progressive development is tempered by the strong traditional culture that persists among the Bamileke and the province's other major ethnic group, the Bamum (sometimes Bamoum, Bamun, Bamoun).

The Centre Region (French: région du Centre) occupies 69,000 km of the central plains of the Republic of Cameroon. It is bordered to the north by the Adamawa Region, to the south by the South Region, to the east by the East Region, and to the West by the Littoral and West Regions. It is the second largest (after East Region) of Cameroon's regions in land area. Major ethnic groups include the Bassa, Ewondo, and Vute.

Yaoundé, capital of Cameroon, is at the heart of the Centre, drawing people from the rest of the country to live and work there. The Centre's towns are also important industrial centres, especially for timber. Agriculture is another important economic factor, especially with regard to the province's most important cash crop, cocoa. Outside of the capital and the plantation zones, most inhabitants are sustenance farmers.

The Northwest Region, or North-West Region (French: Région du Nord-Ouest) is a region with special status in Cameroon. Its capital is Bamenda. The Northwest Region was part of the Southern Cameroons, found in the western highlands of Cameroon. It is bordered to the southwest by the Southwest Region, to the south by the West Region, to the east by the Adamawa Region, and to the north by Nigeria. Various Ambazonian nationalist and separatist factions regard the region as being distinct as a polity from Cameroon.

In 1919, the Northwest Region became solely administered by the United Kingdom. In 1961, the region joined the Cameroon. Ambazonian separatists regard both the North-West and South-West regions as being constituent components of their envisaged breakaway state.
