It's a contrived holiday by Ron N. Everett who later gave himself the name Maulana Karenga, and his followers. Ron invented the fake holiday back in 1966. Back then Ron Everett was a black nationalist and pretty nasty. He ran the organization called United Slaves (US) which he still heads today under the name The Organization Us or just US. He went to prison from 1971 to 1974 after he and some of his pals tortured two women with a soldering iron and a vise, among other things. Then of course he got a job at California State University Long Beach (CSULB) as the chairman of the Department of Black Studies. Only in California….it appears today he is still at CSULB promoting his fake Kwanzaa holiday and making money off it.
