The Oliver Cromwell Black History Society was formed in 1983 for the preservation and research of Black Heritage in the City of Burlington and throughout the United States. The Society is named for Oliver Cromwell, a Black soldier in the Revolution who was decorated by George Washington and lived in Burlington after the war.
The Society meets each month, and holds an annual Black Heritage Historical Art and Essay Contest for students in Burlington City and Burlington Township. The Society's efforts were also instrumental in the designation of the William Allen School as a historic site on both the National and State Historic Registers. The Society and the Institute work together to encourage young men to represent African-American soldiers in Revolutionary War recreations at the Old Barracks Museum in Trenton, some fifteen miles away.
