Liberty Bell–National Parks Service
The State House bell became a herald of liberty in the 19th century. “Proclaim Liberty Throughout All the Land Unto All the Inhabitants thereof,” the bell’s inscription, provided a rallying cry for abolitionists wishing to end slavery.
13th Amendment to the United States Constitution, adopted in 1865, abolished slavery throughout the United States and ended involuntary servitude except as a punishment for conviction of a crime.
