Today is Halloween! So, let us go back in history and see the backgroynd of this day.
The ancient Celts celebrated the New Year (Samhain) on November 1. On November they ended with harvest, the winter was almost here, and northern people accociated this season with death. The Celts believed that on the New Year’s night the border between the worlds would open and the souls of dead people would come to visit Earth.
In order not to become a victim of ghosts, people tried to look very horribly hoping to scare ghosts. People put the treat outside, in order to satisfy ghosts.
In the 7th century, Pope Boniface IV made November 1 the All Saints Day, which was supposed to glorify the saints and martyrs. Catholic Church replaced the pagan feast by the Christian one, but the ancient traditions preserved.
The main attribute of modern Halloween is “Trick or treat?” – also originates from the 18th century. However, at the end of 19th century people tried to forget about the mystic essence of this feast, turning it into public holiday. Therefore, many superstitious features of Halloween were lost in history.
The name comes from the distorted “All Hallows Even”, which over time become a famous Halloween.
So, “Trick or Treat?”
