11. The World Day of Peace Is Established (1967)
On December 8, 1967, Pope Paul VI proclaimed January 1 as the first ‘World Day of Peace’. This annual observance, rooted in the Catholic Church, calls for dialogue and hopes for a nonviolent future. The inaugural World Day of Peace was celebrated on January 1, 1968, with Pope Paul VI visiting the Bambino Gesù Children’s Hospital in Rome to celebrate Mass and address the children (vaticannews.va).
