The history of the Central African Republic is roughly composed of four distinct periods.
 The earliest period of settlement began around 10,000 years ago when nomadic people first began to settle, farm and fish in the region.
 The next period began around 1,000 to 3,000 years ago when several non-indigenous groups began to migrate into the region from other parts of the continent.
 The third period involved the colonial conquest and rule of the country by France and Germany which spanned from the late 1800s until 1960 when the Central African Republic became an independent state.
 The final period has been the era during which the Central African Republic has been an independent state.
Central Africa is the core region of the African continent which includes Burundi, the Central African Republic, Chad, the Democratic Republic of the Congo, and Rwanda.
 Middle Africa (as used by the United Nations when categorising geographic subregions) is an analogous term that includes Angola, Cameroon, the Central African Republic, Chad, the Republic of the Congo, the Democratic Republic of the Congo, Equatorial Guinea, Gabon, and São Tomé and Príncipe.
 All of the states in the UN subregion of Middle Africa, plus those otherwise commonly reckoned in Central Africa (11 states in total), constitute the Economic Community of Central African States (ECCAS).
 Since its independence in 2011, South Sudan has also been commonly included in the region.
Gabon ( ; ] ), officially the Gabonese Republic (French: "République gabonaise" ), is a sovereign state on the west coast of Central Africa.
 Located on the equator, Gabon is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west.
 It has an area of nearly 270000 sqkm and its population is estimated at 1.5 million people.

Manovo-Gounda St. Floris National Park is a national park and UNESCO World Heritage Site located in the Central African Republic prefecture Bamingui-Bangoran, near the Chad border.
 It was inscribed to the list of World Heritage Sites in 1988 as a result of the diversity of life present within it.
 Notable species include black rhinoceroses, elephants, Sudan cheetahs, leopards, red-fronted gazelles, and buffalo, giraffes, lions; a wide range of waterfowl species also occurs in the northern floodplains.
 The site is under threat due to its rare wildlife dying and animals species being wiped out.
 The western black rhinoceros that was indigenous to the Central African Republic has gone extinct in 2011.
 The site was added to the List of World Heritage in Danger after reports of illegal grazing and poaching by heavily armed hunters, who may have harvested as much as 80% of the park's wildlife.
 The shooting of four members of the park staff in early 1997 and a general state of deteriorating security brought all development projects and tourism to a halt.
 The government of the Central African Republic proposed to assign site management responsibility to a private foundation.
 The preparation of a detailed state of conservation report and rehabilitation plan for the site was recommended by the World Heritage Committee at its 1998 session.
 People are working on breeding programs to revive the natural wildlife.
