In this episode we trace Halloween's extensive transformation from its ancient Celtic origins as Samhain, a festival centered on the veil between worlds, to its current status as a multi-billion-dollar industry. It details how the Catholic Church strategically assimilated pagan practices, rebranding them into Christian observances like All Hallows' Eve, and how Irish and Scottish immigrants brought these traditions, such as carving lanterns, to America. The text further explains how environmental adaptation led to pumpkins replacing turnips, and how the holiday evolved from a night of mischief to a community-focused event before becoming thoroughly commercialized by mass media and corporations. Ultimately, the source illustrates Halloween's continuous reinvention, driven by shifting societal, religious, and, predominantly, economic forces, largely overshadowing its original spiritual meaning.
