Tonight marks the beginning of Kwanzaa, the holiday that celebrates African American culture over seven nights with each night dedicated to one of seven important principles: unity, self-determination, collective work and responsibility, cooperative economics, purpose, creativity and faith. In the WQED Archives, we came across a 1994 Black Horizons interview with civil rights activist and PPS board member Sala Udin that touches upon the history of the holiday. Check it out! | WQED
