On July 8, 1776, the bell in the steeple of the Pennsylvania State House in Philadelphia began to ring, letting the citizens know that an important announcement was about to take place. It was the reading of the Declaration of Independence, a statement by representatives of the 13 American colonies that they would no longer be subject to the rule of the British king. Since then, the Liberty Bell, with its famous crack, has been a symbol of American freedom and patriotism.
