Kwanzaa

The holiday's foundation
The weeklong festival was brought to the United States nearly 40 years ago and has as its centerpiece "Nguzo Saba," or the seven guiding principles, each with its own philosophy. One value is celebrated each day of Kwanzaa, and those principles are:
Umoja (unity). The main priority is to strive for and maintain unity in the family, race, community and nation.
Kujichagulia (self-determination). Celebrants work to name, define, create and speak for themselves.
Ujima (collective work and responsibility). This ideal sees people trying to build and maintain a community together. Problem-solving is a shared responsibility.
Ujamaa (cooperative economics). People's aims are to build and maintain their own stores, shops and other businesses, and to collectively profit.
Nia (purpose). The emphasis is on building and developing a community to restore people to their traditional greatness.
Kuumba (creativity). People do as much as possible to leave their community more beneficial and in better condition than they found it.
Imani (faith). Those celebrating believe in one another as well as in one another's parents, teachers and leaders, and in the righteousness and victory of their struggle.
