Our distant ancestors tried to protect the newborn. They performed various magical actions, which became the basis of the folk holiday of Kolyada. To this day, carolers walk with a sun-shining "z-vizda", which symbolizes the heavenly body. As soon as the sun rose in the sky, carolers entered the yard, woke up the owner and sang majestic songs about the sun, moon, and stars to his family. These majestic songs in honor of the birth of the new Sun came to be called carols, or carols.
With the advent of Christianity, the birth of Jesus Christ began to be celebrated on December 25 (old style) or January 7 (new style). The ancient pagan rite was timed to one of the greatest Christian holidays - Christmas. New religious carols with biblical and Christian images appeared. They have gained the same popularity as the old carols.
This led to the appearance of these groups of carolers who dressed up and performed symbolic actions - as if the arrival of these deceased ancestors into our world. The groups of carolers who came to the Lord symbolized those representatives of the afterlife - the souls of the dead who are returning to Earth at this time. And that's why they were expected in every lord, they believed that where the foot of the caroler steps, there the foot of the dead will not step.
