All Hallows' Eve, or Halloween as it is commonly referred, is a global celebration on October 31. It developed from the ancient Celtic ritual of Samhain, which was, in the simplest terms, a festival celebrating the changing of the seasons from light to dark (summer to winter). This would usually take place around November 1.
Traditionally, a bonfire would be lit, sweets would be prepared, and costumes would be worn to ward off evil spirits as the ancient Celts believed that, at this time of year, the veil separating the worlds of the living and the dead was at its thinnest.
Early Christian officials tried to impose their own holiday in an effort to stop their converts from practicing non-Christian festivals. Pope Gregory III deemed November 1, All Saints' Day, a celebration of Christian martyrs and saints, and November 2 became All Souls Day, a day for remembering the souls of the dead. All Saints' Day later became known as All Hallows' Day, and the previous day, October 31, became known as All Hallows' Eve, then later, Halloween.
Despite the best efforts of the church, people still continued to celebrate Halloween with traditional bonfires, costumes, treats, and a focus on spirits of the dead.
All this history is not meant to confuse Halloween and its Mexican cousin, Dia de Muertos, a.k.a. Dia de Los Muertos, a completely separate celebration that occurs during the same timeframe, October 31 to November 2. While Halloween focuses on the dark and grim aspects of death, Dia de Muertos is a celebration of the connection between the living and the dead, as well as life after death.
While Halloween originated in Europe, the holiday became the celebration we recognize today when it was brought to America by the early settlers. People originally carved out turnips and placed candles inside to ward off evil spirits, but Americans switched from turnips to pumpkins.
In 1820, Washington Irving’s short story, The Legend of Sleepy Hollow, became one of the first distinctly American ghost stories centered around the holiday. Halloween received its biggest transformation within the last 50 or so years, thanks to the creation of big candy corporations, and, of course, Hollywood.
Because of its association with all things dark, spooky, and undead, Halloween became the go-to holiday for the release of most horror films and television shows. Director John Carpenter’s Halloween(1978) is probably the best example, as it changed the public image of the holiday from a night for children to dress up in silly costumes to a night of pure terror.
Every year, cities and towns all over the world celebrate with festivals, parades, and theme park events. No matter how Halloween is celebrated, or which aspects of the holiday are celebrated, it has become a global phenomenon comparable to Christmas in terms of how widespread and important it is to the public conscience.

Trick or Treat: A History of Halloween by Lisa Morton
Halloween aficionado Lisa Morton provides a thorough history of this spooky day. She begins by looking at how holidays like the Celtic Samhain, a Gaelic harvest festival, have blended with the British Guy Fawkes Day and the Catholic All Souls’ Day to produce the modern Halloween, and explains how the holiday was reborn in America, where costumes and trick-or-treat rituals have become new customs.
Morton takes into account the influence of related but independent holidays, especially the Mexican Day of the Dead, as well as the explosion in popularity of haunted attractions and the impact of such events as 9/11 and the economic recession on the celebration today. Trick or Treat also examines the effect Halloween has had on popular culture through the literary works of Washington Irving and Ray Bradbury, films like Halloween and The Nightmare Before Christmas, and television shows such as Buffy the Vampire Slayer and The Simpsons.
Halloween: From Pagan Ritual to Party Night by Nicholas Rogers
Drawing on a fascinating array of sources, from classical history to Hollywood films, Rogers traces Halloween as it emerged from the Celtic festival of Samhain (summer's end), picked up elements of the Christian Hallowtide (All Saints' Day and All Souls' Day), arrived in North America as an Irish and Scottish festival, and evolved into an unofficial but large-scale holiday by the early 20th century.
He examines the 1970s and '80s phenomena of Halloween sadism (razor blades in apples) and inner-city violence (arson in Detroit), as well as the immense influence of the horror film genre on the reinvention of Halloween as a terror-fest.
Throughout his vivid account, Rogers shows how Halloween remains, at its core, a night of inversion, when social norms are turned upside down, and a temporary freedom of expression reigns supreme. He examines how this very license has prompted censure by the religious right, occasional outrage from law enforcement officials, and appropriation by left-leaning political groups.
Death Makes a Holiday: A Cultural History of Halloween by David J. Skal
Using a mix of personal anecdotes and brilliant social analysis, Skal examines the amazing phenomenon of Halloween, exploring its dark Celtic history and illuminating why it has evolved—in the course of a few short generations—from a quaint, small-scale celebration into the largest seasonal marketing event outside of Christmas.
Traveling the country, Skal profiles a wide cross-section of American hard-nosed business men who see Halloween in terms of money; fundamentalists who think it is blasphemous; practicing witches who view it as sacred; and more ordinary men and women who go to extraordinary lengths, on this one night only, to transform themselves and their surroundings into elaborate fantasies.
Firmly rooted in a deeper cultural and historical analysis, these interviews seek to understand what the various rituals and traditions associated with the holiday have to say about our national psyche.

A Season with the Witch: The Magic and Mayhem of Halloween in Salem, Massachusetts by J. W. Ocker
Salem, Massachusetts may be the strangest city on the planet. A single event in its 400 years of history—the Salem Witch Trials of 1692—transformed it into the Capital of Creepy in America. But Salem is a seasonal town—and its season happens to be Halloween.
Every October, this small city of 40,000 swells to close to half a million as witches, goblins, ghouls, and ghosts (and their admirers) descend on Essex Street.
For the fall of 2015, occult enthusiast and Edgar Award–winning writer J.W. Ocker moved his family of four to downtown Salem to experience firsthand a season with the witch, visiting all of its historical sites and macabre attractions. In between, he interviews its leaders and citizens, its entrepreneurs and visitors, its street performers and Wiccans, its psychics and critics, creating a picture of this unique place and the people who revel in, or merely weather, its witchiness.
The Pagan Mysteries of Halloween: Celebrating the Dark Half of the Year by Jean Markale
During the night of Samhain, the Celtic precursor of today's holiday, the borders between life and death were no longer regarded as insurmountable barriers. Two-way traffic was temporarily permitted between this world and the Other World, and the wealth and wisdom of the sidhe, or fairy folk, were available to the intrepid individuals who dared to enter their realm.
Jean Markale enriches our understanding of how the transition from the light to the dark half of the year was a moment in which time stopped and allowed the participants in the week-long festival to attain a level of consciousness not possible in everyday life, an experience we honor in our modern celebrations of Halloween.

Zecker: The International Workers Order (IWO) was a consortium of left-wing ethnic self-insurance societies that was born in 1930 in the "languages division" of the Communist Party USA. The Order envisioned its mission as more capacious than writing accident and death policies and, at its height, enlisted more than 188,000 black, white, Hispanic, and Arabic members.
However, "English" lodges, for 2nd-generation white ethnics and other members, were established, too, and many such lodges had white and black members meeting in the same lodge. The Order had a national president and general secretary, but the language societies and the African American Lincoln-Douglass Society and "Spanish" Cervantes Society were granted a lot of autonomy. 
Marcantonio also decried the wartime internment of Japanese Americans, for which he received letters of thanks from Nissei, including a letter from an internee that may have been dearest to his heart.
ecker: The IWO afforded members a dizzying array of social activities; they created a kind of lived progressive milieu. Their own sports leagues were integrated, with black, white, and Hispanic baseball players competing in IWO leagues in places as varied as Los Angeles, Providence, Jersey City, and Canton, Ohio, as early as the 1930s. During these IWO games, petitions demanding the integration of the Major Leagues were passed through the stands. In other sporting events, fun, interracialism and radical identity mixed, too. The African American Chicago Defender publicized these tournaments.
