Kwanzaa -- the holiday and the founder

Here is the basis of Kwanzaa:

"The name Kwanzaa derives from the Swahili phrase "matunda ya kwanza", meaning "first fruits". The choice of Swahili, an East African language, reflects its status as a symbol of Pan-Africanism, especially in the 1960s, though most African-Americans have West African ancestry. Karenga stated "People think it's African, but it's not. I came up with Kwanzaa because Black people wouldn't celebrate it if they knew it was American.

Central to Karenga's collectivist doctrine are the Nguzo Saba, the Seven Principles of Blackness, which are reinforced during the seven days of Kwanzaa:
Umoja (unity)—To strive for and maintain unity in the family, community, nation, and race.
Kujichagulia (self-determination)—To define ourselves, name ourselves, create for ourselves, and speak for ourselves.
Ujima (collective work and responsibility)—To build and maintain our community together and make our brother's and sister's problems our problems and to solve them together.
Ujamaa (cooperative economics)—To build and maintain our own stores, shops, and other businesses and to profit from them together.
Nia (purpose)—To make our collective vocation the building and development of our community in order to restore our people to their traditional greatness.
Kuumba (creativity)—To do always as much as we can, in the way we can, in order to leave our community more beautiful and beneficial than we inherited it.
Imani (faith)—To believe with all our heart in our people, our parents, our teachers, our leaders, and the righteousness and victory of our struggle."

Here is the founder of Kwanzaa:

"Maulana Karenga (born July 14, 1941), also known as Ron Everett, is a controversial African American author and political activist who was once convicted of felony assault and false imprisonment. He is best known as the founder of Kwanzaa, a week-long Pan-African celebration observed each year from December 26 to January 1, initiated in California in 1967.

At the beginning of the 1960s, Karenga met Malcolm X and began to embrace Black nationalism. Following the Watts riots in 1965, he interrupted his doctoral studies at UCLA and joined the Black Power movement. During this time, he took on the title "maulana", Swahili for "master teacher." maulana also meant lord. He formed the US Organization, an outspoken Black nationalist group.
In 1969, Us and the Black Panthers disagreed over who should head the new Afro-American Studies Center at UCLA. According to a Los Angeles Times article, Karenga and his supporters backed one candidate, the Panthers another. The Black Student Union set up a coalition to try to bring peace between the groups, which ended when two members of the Black Panthers, John Jerome Huggins and Alprentice "Bunchy" Carter were shot dead in an altercation.

In 1971 Karenga, Louis Smith, and Luz Maria Tamayo were convicted of felony assault and false imprisonment for assaulting and torturing two women from the Us organization, Deborah Jones & Gail Davis, over a two day period. [4] A May 14, 1971 article in the Los Angeles Times described the testimony of one of the women: "Deborah Jones, who once was given the Swahili title of an African queen, said she and Gail Davis were whipped with an electrical cord and beaten with a karate baton after being ordered to remove their clothes. She testified that a hot soldering iron was placed in Ms. Davis's mouth and placed against Ms. Davis's face and that one of her own big toes was tightened in a vise. Karenga also put detergent and running hoses in their mouths, she said.

In Karenga's words "The Christian is our worse enemy. Quiet as it's kept, it was a Christian who enslaved us. Quiet as it's kept it's a Christian who burns us. Quiet as it's kept it's a Christian who beats us down on the street; and quiet as it's kept when the thing goes down it'll be a Christian that's shooting us down. You have to face the fact that if the Christian is doing all this there must be something wrong with Christanity."
