The City of Birmingham on Tuesday announced a new exhibit at City Hall honoring 100 years of service for a historic Black fraternity and two sororities, including the sorority of Democratic presidential candidate Kamala Harris, a Howard College graduate.

Harris is affiliated with Alpha Kappa Alpha Sorority, Inc., an international service organization, that was founded on the campus of Howard University in Washington, D.C. in 1908.

It is the oldest Greek-letter organization established by African American college-educated women.

The photo exhibit at Birmingham City Halls honors the histories of three groups and their service to the city: the Tau Sigma Chapter of Phi Beta Sigma Fraternity, Inc.; the Alpha Phi Chapter of Omega Psi Phi Fraternity Inc.; and the Omicron Omega Chapter of Alpha Kappa Alpha Sorority, Inc.

All three area chapters were founded in 1924.

“They’ve inspired us,” said Birmingham Mayor Randall Woodfin, at a ceremony to mark the start of the Three Legacies, One Century exhibit on the second floor of City Hall.

“Sustaining an organization for 100 years is a major feat,” Woodfin said. “These college-educated African Americans maintained their mission to serve our community for decades in spite of the many challenges and tribulations; persisting through Jim Crow, through segregation and inspiring others, by building up our community, offering scholarships, educating young people, and serving as role models.”

The exhibit honoring the local chapters will be on display through September, Monday through Friday, 8 a.m. to 5 p.m., on the second floor of City Hall.
