Chaharshanbe Suri history belongs to many years ago. Most historians believe it is originated from the festival of Hamaspathmaedaya, which was held in the last five days of the year in honor of the dead souls. The bonfires were lit up to welcome the spirit of the dead. They thought that flames, as a sign of God, can protect the departed souls from evil. That’s why people celebrate Chaharshanbe Suri.
