No one is really sure why Pennsylvania’s Liberty Bell is cracked, but most historians suspect that bad bell-making was to blame! In 1751, the newly formed government of Pennysylvania ordered a new bell to symbolize its belief in religious freedom. The bell cracked soon after its arrival from London. A pair of smithees (metal worker) quickly tried to repair it, but by 1846 it had developed a pretty severe crack. While the bell hasn’t been rung since, it has come to symbolize freedom of all types, including freedom from slavery.
