By the 1930s, Halloween had moved away from its religious roots and into a secular holiday. Community leaders in the US encouraged the celebration of Halloween (minus the more macabre aspects). Instead, the focus shifted towards parties, games, and enjoying seasonal foods and sweets.
In an effort curb the growing concerns around pranks that had simply turned into outright vandalism, trick or treating grew in popularity between the 1920s and the 1950s. It was seen as a way to placate troublemakers with sweets, but it was also a way to involve entire communities in the spirit of the holiday.
Today, it’s the parties, trick or treating, and ghost stories that most people think about and enjoy when 31st October rolls around. In fact, the concept of telling ghost stories has grown so much that film studios compete against each other every year to put out the season’s most terrifying horror flick.
