West Region (Cameroon) in the context of "Cameroon line"

In Cameroon, Islam is a minority faith practiced by around 30.6% of the total population as of 2022. Among Cameroonian Muslims, approximately 40% identify themselves as Non-denominational, 27% Sunni, 2% Ahmadi and 3% Shia, while the majority of the rest do not associate themselves with a particular group and sect.

In Cameroon, 48% of Muslims belong to a Sufi Tariqah (order). The Fulani, a pastoral nomadic group, spread Islam in early 19th century West Africa largely through commercial activity and Sufi brotherhoods (Qadiri and Tijani). In the northern provinces, the locally dominant Fulani is overwhelmingly Muslim. Other ethnic groups, known collectively as the Kirdi, generally practice some form of Islam. The Bamoun ethnic group of the West Province is also largely Muslim.

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 Adamawa Region (French: Région de l'Adamaoua) is a constituent region of the Republic of Cameroon. It borders the Centre and East regions to the south, the Northwest and West regions to the southwest, Nigeria to the west, the Central African Republic (CAR) to the east, and the North Region to the north.

This mountainous area forms the barrier between Cameroon's forested south and savanna north. At almost 64,000 km in land area, the Adamawa is the third largest of Cameroon's ten regions. The land is rugged and sparsely populated, however, as most is devoted to the rearing of cattle. The Muslim Fulbe (Fulani) form the major ethnic group, though Tikar, Gbaya, and other peoples are present in lesser numbers.

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.
