There was a flurry of activity at the African American Museum of Philadelphia, a celebration of liberation on the 154th anniversary of Juneteenth, commemorating the abolition of slavery in 1865.

“This is 154 years of this tradition. That makes it a true tradition so it makes sense to keep passing it on and recognize what it stands for, to really give a date to think about our liberty and to remember that it was not always ours,” Wallace said.

On Wednesday night, there was also an outdoor drum and dance performance held at the African American Museum of Philadelphia.

All of the programs offered Wednesday were free with admission to the museum.
