Observance of Halloween faded in the South of England from the 17th century onwards, being replaced by the commemoration of the Gunpowder Plot on November 5. However it remained popular in Scotland, Ireland and the North of England. It is only in the last decade that it again became popular in the south of England, but as an entirely Americanized version.
The custom survives most accurately on the Island of Ireland, where the last Monday of October is a public holiday. All schools close for the following week for mid-term, commonly called the Halloween Break. As a result Ireland and Northern Ireland are the only countries where children never have school on Halloween and are therefore free to celebrate it in the ancient and time-honored fashion.
The custom of trick-or-treating is thought to have evolved from the European custom called souling, similar to the wassailing customs associated with Yule. On November 2, All Souls' Day, beggars would walk from village to village begging for "soul cakes" - square pieces of bread with currants. Christians would promise to say prayers on behalf of dead relatives helping the soul's passage to heaven. The distribution of soul cakes was encouraged by the church as a way to replace the ancient practice of leaving food and wine for roaming spirits at the Samhain.

In Celtic parts of western Brittany, Samhain is still heralded by the baking of kornigou. Kornigou are cakes baked in the shape of antlers to commemorate the god of winter shedding his "cuckold" horns as he returns to his kingdom in the Otherworld.
