Earlier, people used to selebrate harvest festivals using everything that they had. Ofcourse the simplest thing they had was a broom in the farmland or a barn for sweeping purpose. Using broom they used to be joyful and dance. This very act was against the method/s of churches and churches felt it a threat to their belief. This is also one more reason why they were declared as witches and
wizards and executed. The catholic churches murdered millions who themselves were also the descendents of pagan forefathers.
