When it comes to Halloween, this spooky celebration has spread far and wide! See what countries celebrate Halloween. There are plenty of fascinating ways Halloween is observed around the world.
1. The Origins of Halloween
The name “Halloween” comes from All Hallows’ Eve, the night before All Hallows’ Day (All Saints’ Day) on November 1, a Christian festival honoring saints and praying for departed souls.
During the Middle Ages, people observed this eve with prayers, bell-ringing, and “souling,” where children and the poor went door-to-door offering prayers for the dead in exchange for soul cakes (an early form of trick-or-treating).
Many Halloween customs also draw from the ancient Gaelic festival of Samhain, celebrated on October 31 in Ireland, Scotland, and the Isle of Man.
Samhain marked the end of the harvest and the start of winter, a time when the veil between the living and spirit worlds was believed to be thinnest.
Over centuries, these Christian and Celtic practices intertwined. Costumes, lanterns carved from turnips, and nighttime games of divination became common features of the festival.
Irish and Scottish immigrants brought these customs to North America in the 19th century, where they evolved into the festive, candy-filled celebration we know today and eventually spread around the world.
