Cabinda Province in the context of "Democratic Republic of the Congo"

Angola, officially the Republic of Angola, is a country on the western coast of Southern Africa. It is the second-largest Portuguese-speaking (Lusophone) country after Brazil in both total area and population and is the seventh-largest country in Africa. It is bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to the west. Angola has an exclave province, the province of Cabinda, that borders the Republic of the Congo and the Democratic Republic of the Congo. The capital and most populous city is Luanda.

Angola has been inhabited since the Paleolithic Age. After the Bantu expansion reached the region, states were formed by the 13th century and organised into confederations. The Kingdom of Kongo ascended to achieve hegemony among the other kingdoms from the 14th century. Portuguese explorers established relations with Kongo in 1483. To the south were the kingdoms of Ndongo and Matamba, with the Ovimbundu kingdoms further south, and the Mbunda Kingdom in the east.

The Republic of the Congo, also known as Congo-Brazzaville, the Congo Republic or simply the Congo (its name from 1971 to 1997; the last ambiguously also referring to the neighbouring Democratic Republic of the Congo), is a country located on the western coast of Central Africa to the west of the Congo River. It is bordered to the west by Gabon, to the northwest by Cameroon, to the northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to the south by the Angolan exclave of Cabinda, and to the southwest by the Atlantic Ocean.

The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. From the 13th century, the present-day territory was dominated by a confederation led by Vungu which included Kakongo and Ngoyo. The Tio Kingdom emerged in the 14th century, and Loango in the 16th century. In the late 19th century France colonised the region and incorporated it into French Equatorial Africa. The Republic of the Congo was established on 28 November 1958 and gained independence from France in 1960. It was a Marxist–Leninist state from 1969 to 1992, under the name People's Republic of the Congo (PRC). The country has had multi-party elections since 1992, but a democratically elected government was ousted in the 1997 Republic of the Congo Civil War. Denis Sassou Nguesso has been president since 1979, except for the period from 1992 to 1997.

The Angola–Democratic Republic of the Congo border is 2,646 km (1,644 mi) in length and consists of two non-contiguous sections: a 225 km (140 mi) section along the border with Angola's province of Cabinda, running from the Atlantic Ocean to the tripoint with the Republic of Congo, and a much longer 2,421 km (1,504 mi) section running from the Atlantic to the tripoint with Zambia.

Colonization of the Congo Basin refers to the European colonization of the Congo Basin of tropical Africa. It was the last part of the continent to be colonized. By the end of the 19th century, the Basin had been carved up by European colonial powers into the Congo Free State, the French Congo and the Portuguese Congo (modern Cabinda Province of Angola).

The western lowland gorilla (Gorilla gorilla gorilla) is one of two Critically Endangered subspecies of the western gorilla (Gorilla gorilla) that lives in montane, primary and secondary forest and lowland swampland in central Africa in Angola (Cabinda Province), Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea and Gabon. It is the nominate subspecies of the western gorilla, and the smallest of the four gorilla subspecies.

The western lowland gorilla is the only subspecies kept in zoos with the exception of Amahoro, a female eastern lowland gorilla at Antwerp Zoo, and a few mountain gorillas kept captive in the Democratic Republic of the Congo.

Kakongo was a small kingdom located on the Atlantic coast of Central Africa, in the modern-day Republic of the Congo and Cabinda Province, Angola. In the 13th century, it formed part of a confederation led by Vungu. Along with its neighboring kingdoms of Ngoyo and Loango, Kakongo became an important political commercial center during the 17th through 19th centuries. The people speak a dialect of the Kikongo language and thus may be considered a part of the Bakongo ethnicity. Kakongo was a vassal of the Kingdom of Kongo for a part of its history.
