Origins of Halloween

Halloween traces back 2,000+ years to the Celtic festival of Samhain, marking summer’s end and the start of winter. With Christianity’s spread, Samhain customs blended into All Hallows’ Eve, the night before All Saints’ Day — eventually shortened to “Halloween.”

Etymology: The word Halloween derives from “All Hallows’ Evening.”

How Halloween Took Off in America

Irish immigrants carried these traditions to the U.S. in the 1800s. Trick‑or‑treating gained traction in the early 20th century and surged in the 1940s–50s alongside suburban growth and candy marketing, locking Halloween into American culture.
