December 26 is the start of Kwanzaa, a celebration of the African American community, culture and family. 
The celebration runs until January 1, 2025.

Kwanzaa emerged during the Black Freedom Movement of the 1960s as a way to reconnect Black communities in the U.S. with important African cultural traditions that were severed by the transatlantic slave trade. It also promotes unity and liberation.

“It was also shaped by that defining decade of fierce strivings and struggles for freedom, justice and associated goods waged by Africans and other peoples of color all over the world in the 1960s,” Maulana Karenga, the holiday’s founder, wrote in his annual Kwanzaa address in 2023. “Kwanzaa thus came into being, grounded itself and grew as an act of freedom, an instrument of freedom, a celebration of freedom and a practice of freedom.”

Karenga, an African American author, activist and professor, founded Kwanzaa following the Watts Riots, also known as the Watts Rebellion, in Los Angeles in 1965.

KWANZAA 2024

 

 
Designer: Ethel Kessler 
Artist: Ekua Holmes

Ekua Holmes produced one of the most vibrant and exciting stamps of 2024 for USPS using a unique combination of styles –  “collage based and her subjects, made from cut and torn papers, investigate family histories, relationship dynamics, childhood impressions, the power of hope, faith, and self-determination”. (About — Ekua Holmes)

[This stamp] was inspired by a live performance by dancers from OrigiNation Cultural Arts Center, witnessed by artist Ekua Holmes, during a Kwanzaa event in Roxbury, MA. The stamp depicts three young performers — a male drummer and behind and to either side of him, two female dancers. He wears a dark blue, green, and orange kufi; a white shirt, and pants with a geometric black and white mud cloth-like pattern. His djembe — blue with a white drumhead — hangs from his neck by a red strap. The two dancers wear orange dresses and gold jewelry. One has a red hair band and all three figures have silhouetted black skin and hair. The floor beneath their feet is diamond patterned in shades of green, while the background features triangles in shades of red. Each dancer extends a knee and a bit of orange skirt beyond the image frame, into the white margin of the stamp.

The history and origins of Kwanzaa covers a broad expanse of time and space. It is grounded in African harvest celebrations that began at the dawn of advanced human civilizations as we developed more effective ways to grow food, feed ourselves, and thrive. Kwanzaa emerged from its grounding in ancient African history to come into existence during the 1960’s Black Freedom Movement as Black Americans sought to restore our connections to the best of African culture and history.
