The observance of the Celtic festival of Samhain-derived traditions varies across different nations. In the Iberian Peninsula, specifically within the borders of the Portuguese Republic, practices tied to honoring the deceased are deeply rooted in the cultural calendar around late October and early November. While a distinct festival with costumes and trick-or-treating has not historically been a mainstream practice, its presence is discernable, particularly among younger generations and in urban areas.
The rise in visibility of events resembling the Americanized version of October 31st can be attributed to globalization and media influence. Commercial aspects, such as themed parties and decorations, have become increasingly popular, albeit not supplanting traditional customs. Instead, they exist alongside established celebrations, contributing to a diverse cultural landscape. The benefits of this growing adoption can be seen in increased social interaction and creative expression, while the historical context involves a gradual shift towards integrating global trends with local heritage.
