In the old days of”Marriage by Capture,” the bride had to be dragged or carried across the threshold because she was being kidnapped, and therefore would not have gone peacefully into the groom’s home. In earlier times, people thought that a family’s demons followed the woman and to keep her family demons from going into the groom’s home, she was carried across the threshold upon her entering for the first time. In the times of the Romans, when men ALWAYS opened doors for ladies, this would just seem like a natural thing to do, but they believed it to be such bad luck for the bride to trip or stumble crossing the threshold of her new house, that if it were to happen, the marriage would be doomed to failure. So the groom would carry his bride over the threshold thus making sure she didn’t trip.
