The celebration honors African heritage in African-American culture, and is observed from December 26 to January 1, culminating in a feast and gift-giving. Kwanzaa has seven core principles (Nguzo Saba): Unity, self-determination, collective work and responsibility, cooperative economics, purpose, creativity, and faith. It was created by Maulana Karenga, and was first celebrated in 1966–67.
