Answer:
It is believed that Halloween is a pagan ritual derived from pre-Christian festivals celebrated by druids, which the church could not eradicate. In the modern world, many celebrate this holiday, knowing very little about it. In fact, Halloween has Christian roots. The holiday falls on October 31 thanks to the pope.
The historian Nicholas Rogers, who studied the origins of Halloween, noted that, despite attempts to connect its origin with the ancient Roman festival of Parentals, which was celebrated on February 13-21, the prototype of Halloween, most likely, originated only with the advent of the Celtic pagan festival Samhain. Samhain was a holiday for all the peoples of the British Isles and was strongly associated with death and the supernatural. At the same time, there is no evidence that in pagan times the holiday had any special significance, except for agricultural and seasonal. In 601, Pope Gregory I instructed the missionaries not to fight pagan holidays, but to convert them to Christian ones - according to his plan, this should contribute to the Christianization of Northern Europe. By the 8th century, Samhain became the Day of All Souls and the Day of All Saints (November 1), in which it was considered acceptable from the point of view of religion to speak with the dead.
