Yesterday, I learned that the current American Halloween tradition of giving candy to costumed kids represents an uneasy truce between civilization and the trickster spirit.
There are a lot of traditions regarding Samhain, many of which include bonfires and naked dancing (because they all included bonfires and naked dancing. Who are we kidding?) But in the Irish farmlands, Samhain was mischief night, at least for adolescent and young adult boys (we assume they were boys.)
The idea was to haze the local grownups, particularly the crabby ones who yelled at clouds or didn't like young'uns much. There were plenty of old standby pranks: carving faces into produce or shepherding livestock to the rooftops to dressing up like ghosts and monsters and ambushing them at night to send them running.
It was a mostly accepted tradition. Teenagers got to go bananas for one day a year, and were (more or less) on ~~good~~ better behavior for the rest of the time. Skittish folk did the Purge thing of holing up in safety.
And then the Irish and their wily teenagers came to the United States.
Our Halloween pumpkin-smashers were called guisers from those in disguise. Note that there were other guising traditions that exchanged DNA with our dark cabal of malicious tricksters. (One fond one was of drunkards who'd sing at your house until you gave them food, beer or money to leave), but for our antagonists, it was the black bloc of the time, a means to ensure that you weren't identified at the scene of a fresh crime.
Do an image search of "vintage halloween costumes" and you won't see people trying to look like Mario or Misty or Mickey or Megatron, but just people in spooky clothes and spookier masks clearly up to no good. You didn't buy your costume, rather you made it with whatever was on hand, and hence there were a lot of sheet ghosts.
In the early 20th century pranking in the States achieved an apogee (a nadir?). The great depression drove everyone to despair, and wanton destruction that once was meager and required a morning of repair might be the fire that broke the farm. Also some pranks went wrong, leading to a resonance cascade failure, starting a wildfire or other unnatural disaster.
And then WWII happened and we were not only trying to salvage what we can, but had real (alleged) monsters that might even be infiltrating the homefront as we speak. Pranksters then were losing the war for the Allies and serving the Axis, even if inadvertently.
Something had to be done, and even President Truman got involved regarding The Halloween Problem.
A couple of early attempts to trade Halloween for a nicer holiday failed drastically, and the pranking continued.
Eventually an armistice came when the neighborhood spooky pageant emerged. Creative neighbors would turn a part of their house into a spooky diorama and light the path with candles and jack-o-lanterns and other Halloween kitsch. Rather than hopping onto a war-wagon (that's a mischief team stuffed into a motor vehicle) they'd go visit the local spooktaculars. (This would in turn fuel the haunted house craze, assisted by Disney's Haunted Mansion opening in 1953)
Feeding the roaming guests kept the rotten eggs away. While there was candy, there were also cookies, apples, (toothbrushes, Chick tracts) and other treats. Sometimes there were activities, though I never could figure out bobbing for apples.
The transition from free-form snacks to packaged candy came due to The Candyman who was much less exciting than the movie version. Ronald Clark O'Bryan made custom Pixy Stix laced with potassium cyanide, one of which he fed to his son, Timothy on Halloween, 1974. He was far removed from a master criminal, and inconsistencies in his story kept the police interested until it all fell apart. He was also deep in debt and took out a beefy life-insurance policy on his son. The police didn't have to investigate too deeply.
O'Bryan was executed in 1984, but by then the damage he had done to Halloween had been done, and moral panics would persist about tampered Halloween treats. By then it was common for everyone to just give packaged candy.
Related was also the 1982 Tylenol poisonings. They had nothing to do with Halloween, but secured into the public conscience that people could tamper with products in order to cause mayhem to the general public. And at least by my recollection, this not only ended all Halloween offerings of home-made cookies by kitchen-minded families but also made sure safety seals were added to every food and hygiene product in the US.
By the aughts, everyone was familiar with the "fun-sized" candy which was totally not that fun.
(It's noted by some that Tylenol doesn't really need all that much assistance to poison you. As painkillers go, it's hard on the system, easy to overdose, and Tylenol poisoning incurs a yearly body count in the US. There's been an ongoing effort to convince the FDA to rethink its approval of Tylenol, for convincing cause. But big pharma really wants to keep selling you stuff. Anyway I digress.)
These days, we hear a lot of calls from the religious right for the end of celebrations of Halloween, a holiday too macabre for families who purport to have family values. Many churches tell their parishioners to skip the holiday for Jesus, while more clever churches simply hold a party there as an alternative to trick-or-treating. Some churches forbid witches, or even only allow approved costumes from the approved costume list. There's a lot of, as Dan McClellan would put it, costly identity signaling between members of right-wing religious ministries to show they're on team-purity.
But this is not a holiday we celebrate to honor benign gods and favored spirits. This is not an Apollonian holiday we keep up for the morale of the people, rather it's a Dionysian holiday, one we celebrate in respect for spirits who would wrong us if we don't acknowledge their presence and the unsteady peace they offer in exchange for our tribute.
Hallowe'en as it is celebrated in the US is a rite we engage in every year to keep away malevolent trickster monsters, who will return (and will start fires) if we don't placate them with yearly treats.
