The Centre International des Civilisations Bantu (CICIBA) is a cultural organization based in Libreville, Gabon.
 Established at the initiative of Gabonese president Omar Bongo on January 8, 1983, it is the world's primary organization dedicated to the study of the Bantu peoples.
 In 2012, it was announced that the center would be rehabilitated after its abandonment in 1988 for lack of funding.
Wachira (also "Wacira" or "Wachiira") is a male name among the Kikuyu, also called Gikuyu, and related Bantu peoples of Kenya.
 Derived from "Chira" or Case.
 "Wa" signifies that one who deals with cases.
 Some contend that the name signifies one who feels and senses much that they do not fully understand, and can be deeply influenced through the thoughts of others without realizing just how you are being affected.
 Notable people with the name include:
The Bantu mythology is the system of myths and legends of the Bantu peoples of Africa.
 Although Bantu peoples account for several hundred different ethnic groups, there is a high degree of homogeneity in Bantu cultures and mythologies, just as in Bantu languages.
 The phrase "Bantu mythology" usually refers to the common, recurring themes that are found in all or most Bantu cultures.
The Twa of the Lukanga Swamp of Zambia are one of several fishing and hunter-gatherer castes living in a patron–client relationship with farming Bantu peoples across central and southern Africa.
 The Lukanga Twa live primarily among the Lenje, and speak the Lenje language.
Kenya is a multi-ethnic state in the Great Lakes region of East Africa.
 It is inhabited primarily by Bantu and Nilotic populations, with some Cushitic-speaking ethnic minorities in the north.
 Its total population was estimated at 47 million as of 2017.
Bantu Kavirondo is the former name given to some of the Bantu peoples of western Kenya (e.g., the Luhya and Kisii) under the early colonial regime of British East Africa.
 Kavirondo Gulf (Winam Gulf) and the surrounding area of "Kavirondo" derive from the same name.
 They were designated “Bantu" Kavirondo in contradistinction to the “Nilotic Kavirondo” (Luo).
Bantu peoples is used as a general label for the 300–600 ethnic groups in Africa who speak Bantu languages.
 They inhabit a geographical area stretching east and southward from Central Africa across the African Great Lakes region down to Southern Africa.
 Bantu is a major branch of the Niger–Congo language family spoken by most populations in Africa.
 There are about 650 Bantu languages by the criterion of mutual intelligibility, though the distinction between language and dialect is often unclear, and "Ethnologue" counts 535 languages.
Kikuyu or Gikuyu (Kikuyu: "Gĩkũyũ" ] ) is a language of the Bantu family spoken primarily by the Kikuyu people ("Agĩkũyũ") of Kenya.
 Numbering about 7 million (22% of Kenya's population), they are the largest ethnic group in Kenya.
 Kikuyu is spoken in the area between Nyeri and Nairobi.
 Kikuyu is one of the five languages of the Thagichu subgroup of the Bantu languages, which stretches from Kenya to Tanzania.
 The Kikuyu people usually identify their lands by the surrounding mountain ranges in Central Kenya which they call "Kĩrĩnyaga".
The Twa of the Kafue Flats wetlands of Zambia are one of several fishing and hunter-gatherer castes living in a patron–client relationship with farming Bantu peoples across central and southern Africa.
Mzungu (] ) is a Bantu language term used in the African Great Lakes region to refer to people of European descent.
 It is a commonly used expression among Bantu peoples in Kenya, Tanzania, Malawi, Rwanda, Burundi, Uganda, Democratic Republic of Congo, Comoros, Mayotte and Zambia, dating back to the 18th century.
 Literally translated it meant "someone who roams around" or "wanderer."
 The term was first used in the African Great Lakes region to describe European explorers in the 18th century, apparently as a result of their extensive travelling all over the world.
 The word Mzungu comes from Kiswahili, where "zungu" or "zunguka" is the word for spinning around on the same spot.
 "Kizunguzungu" is Kiswahili for a dizziness.
 The term is now used to refer to "someone with white skin" or "white skin".
 The word Mzungu in Swahili can also mean someone who speaks English.
 A person in Swahili is "Mtu" and "English" in Swahili is "Kizungu" hence the combination of the two words to make up a word "Mzungu."
