Bells told people of happy events, such as weddings and births or, sometimes had to announce unpleasant events such as a death or a funeral . Sometimes bells were used for giving people warnings of an enemy's approach or spreading good news victory
In many places today, bells are perhaps most commonly associated with announcing when religious services are going to take place. They're frequently rung during celebrations and continue to play a part in many people's lives
