Commemorating the 250th Anniversary of the Pennsylvania Abolition Society
This year marks the 250th anniversary of the Pennsylvania Abolition Society (PAS), one of the nation’s earliest organizations dedicated to ending slavery and advancing racial justice. HSP, which holds the papers of the PAS, is commemorating this milestone with a series of exhibits and programs highlighting the Society’s legacy and ongoing relevance.
​
This past May, we honored the PAS with our Heritage Award in recognition of 250 years of advocacy on behalf of Black Americans.

Voices of the Community: Local Black Preservation explores the history, migration, and preservation of African American communities in Philadelphia, Pennsylvania and Lawnside, New Jersey. Curated by community historians and activists, this exhibit uses archival documents such as personal papers, photographs, musical scores, and ephemera to highlight strategies Black individuals and communities utilize to preserve their heritage. The historical formation of organizations, creation of music, and building of communities have resulted in a cultural preservation movement based on principles of self-determination and collective action.
