📜 History & Origins
The feast of All Saints originated in the early centuries of Christianity. Pope Boniface IV consecrated the Roman Pantheon as a Christian church dedicated to the Virgin Mary and all martyrs on May 13, 609, establishing an annual commemoration. Pope Gregory III (731–741) later moved the feast to November 1 and broadened it to honour all saints, known and unknown, and Gregory IV extended the celebration to the entire Western Church in 837. The following day, All Souls' Day (November 2), though not a public holiday in Italy, is when most cemetery visits and remembrances actually take place.
