About Kwanzaa
Kwanzaa is an African American and Pan-African holiday which celebrates family, community and culture. Celebrated from 26 December thru 1 January, its origins are in the first harvest celebrations of Africa from which it takes its name.
The name Kwanzaa is derived from the phrase "matunda ya kwanza" which means "first fruits" in Swahili. Spoken widely in East Africa, Swahili is a Pan-African language, selected by the Sixth Pan African Congress in Tanzania to be the international lingua franca of African people.
Kwanzaa was founded in 1966 by Ron (Maulana) Karenga, founder of the US Organization.
