November 1st, known as All Saints' Day in Christian traditions, is a day dedicated to honoring all saints and martyrs. Its origins are deeply connected to the ancient Celtic festival of Samhain, which marked the end of harvest and a time when the boundary between the living and the spirit world was believed to be thin. As Christianity spread in Europe, the Church strategically aligned All Saints' Day with Samhain to facilitate a smoother transition for pagan communities. Traditionally, the day was marked by church services, visiting graves, communal feasting, bell ringing, and the custom of 'souling' where prayers were exchanged for treats.
