The practice of donning disguises on All Hallows’ Eve has evolved significantly over centuries. Originally rooted in ancient Celtic traditions, the act served to ward off malevolent spirits believed to roam freely on this night. By impersonating these entities, or otherwise obscuring one’s identity, individuals sought to avoid harm or misfortune. This protective measure formed the nascent stages of what is now a widespread celebratory custom.
The adoption of this symbolic dress provided a sense of communal identity and shared experience. As societies evolved, the significance shifted from strict protection to elements of play, performance, and social commentary. The opportunity to temporarily shed everyday roles and adopt alternative personas allowed for creative expression, boundary testing, and often, humorous critique of societal norms. This participatory element became integral to the holiday’s appeal.
