The Liberty Bell, located in Philadelphia, Pennsylvania, is an American bell of great historic significance. The Liberty Bell is perhaps one of the most prominent symbols associated with the American Revolution and the American Revolutionary War. It is one of the most familiar symbols of independence, nationhood and freedom within the United States, and has become an international icon of liberty. 
Its most famous ringing, on July 8, 1776, summoned citizens of Philadelphia for the reading of the Declaration of Independence. Previously, it had been rung to announce the opening of the First Continental Congress in 1774 and after the Battle of Lexington and Concord in 1775.
The inscription on the Liberty Bell reads as follows:
- PROCLAIM LIBERTY THROUGHOUT ALL THE LAND UNTO ALL THE INHABITANTS THEREOF LEV. XXV X.
- BY ORDER OF THE ASSEMBLY OF THE PROVINCE OF PENSYLVANIA FOR THE STATE HOUSE IN PHILADA
- PASS AND STOW
Casting and early history
The bell was ordered in 1751 by the Pennsylvania Assembly for use in the Pennsylvania State House (now known as Independence Hall) in Philadelphia. It was cast by the Whitechapel Bell Foundry in London and delivered to Philadelphia in late August/early September 1752.
