Christmas might be over, but Kwanzaa is just getting started.

Today marks the start of Kwanzaa, also spelled Kwanza (with one 'a' at the end). It's a seven-day non-religious holiday observed in the U.S., meant to honor African Americans' ancestral roots. The celebration lasts until January 1.

The name comes from the Swahili phrase "matunda ya kwanza," which means "first fruits."

Created in 1966 by Maulana Karenga, a Black nationalist and professor of Pan-African studies at California State University at Long Beach, Kwanzaa became popular in the 1980s and 1990s in tandem with the Black Power movement -- making up the trio of winter holidays along with Hanukkah and Christmas.

The holiday is defined by Nguzo Saba, or the seven principles. Each day of the festival is dedicated to a specific principle, marked by lighting a new candle on the kinara, a seven-branched candelabra.

Even though Kwanzaa isn't as widely celebrated as it used to be, its seven principles still hold true for some. Here's a look at what those principles are, and what they mean.

UMOJA

Umoja means unity in Swahili.

Karenga defines this on his Kwanzaa website as: "To strive for and maintain unity in the family, community, nation and race."

KUJICHAGULIA

Or self-determination. This principle refers to defining, naming, creating and speaking for oneself.

UJIMA

Translated as "collective work and responsibility," ujima refers to uplifting your community.

"To build and maintain our community together and make our brother's and sister's problems our problems and to solve them together," Karenga writes.

UJAMAA

Cooperative economics. Similar to ujima, this principle refers to uplifting your community economically. "To build and maintain our own stores, shops and other businesses and to profit from them together," he writes.

NIA

Nia means purpose.

Karenga expands on this principle with, "To make our collective vocation the building and developing of our community in order to restore our people to their traditional greatness."

KUUMBA

Meaning "creativity," Karenga defines this principle as "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

The final principle translates to "faith."

Karenga defines this as faith in community, writing, "To believe with all our heart in our people, our parents, our teachers, our leaders and the righteousness and victory of our struggle."
