parades and town-wide parties as the featured entertainment. Despite the best efforts of many schools and communities, vandalism began to plague Halloween celebrations in many communities during this time. By the 1950s, town leaders had successfully limited vandalism and Halloween had evolved into a holiday directed mainly at the young. Due to the high numbers of young children during the fifties baby boom, parties moved from town civic centers into the classroom or home, where they could be more easily accommodated. Between 1920 and 1950, the centuries-old practice of trick-or-treating was also revived. Trick-or-treating was a relatively inexpensive way for an entire community to share the Halloween celebration. In theory, families could also prevent tricks being played on them by providing the neighborhood children with small treats. A new American tradition was born, and it has continued to grow. Today, Americans spend an estimated $6 billion annually on Halloween, making it the country's second largest commercial holiday.Today's Halloween TraditionsThe American Halloween tradition of "trick-or-treating" probably dates back to the early All Souls' Day parades in England. During the festivities, poor citizens would beg for food and families would give them pastries called "soul cakes" in return for their promise to pray for the family's dead relatives. The distribution of soul cakes was encouraged by the church as a way to replace the ancient practice of leaving food and wine for roaming spirits. The practice, which was referred to as "going a-souling" was eventually taken up by children who would visit the houses in their neighborhood and be given ale, food, and money. The tradition of dressing in costume for Halloween has both European and Celtic roots. Hundreds of years ago, winter was an uncertain and frightening time. Food supplies often ran low and, for the many people afraid of the dark, the short days of winter were full of constant worry. On Halloween, when it was believed that ghosts came back to the earthly world, people thought that they would encounter ghosts if they left their homes. To avoid being recognized by these ghosts, people would wear masks when they left their homes after dark so that the ghosts would mistake them for fellow spirits. On Halloween, to keep ghosts away from their houses, people would place bowls of food outside their homes to appease the ghosts and prevent them from attempting to enter.Halloween SuperstitionsHalloween has always been a holiday filled with mystery, magic and superstition. It began as a Celtic end-of-summer festival during which people felt especially close to deceased relatives and friends. For these friendly spirits, they set places at the dinner table, left treats on doorsteps and along the side of the road and lit candles to help loved ones find their way back to the spirit world. Today's Halloween ghosts are often depicted as more fearsome and malevolent, and our customs and superstitions are scarier too. We avoid crossing paths with black cats, afraid that they might bring us bad luck. This idea has its roots in the Middle Ages, when many people believed that witches avoided detection
