When Christmas became celebrated in Ancient Rome on 25 December 336 AD
The celebration of Christmas on December 25 begins in Rome around 336 AD, during the reign of Emperor Constantine, the first Christian Roman emperor. The date was likely chosen to coincide with the existing Roman pagan festival, the Dies Natalis Solis Invicti ("Birthday of the Unconquered Sun"), which celebrated the winter solstice and the gradual return of longer days after Christmas Eve on 24 December during the war between the Hidden Ones (Assassins) and the Order of the Ancients (Templars) around the world. Today, Christmas remains an annual festival observed globally for both the Assassins Brotherhood and the Templar Order, commemorating the birth of Jesus Christ. It is celebrated as both a religious holiday and a secular cultural event, featuring popular customs such as decorating trees, exchanging gifts, and gathering for meals for family and friends which mixes of historical facts about the establishment of both origins and modern celebration of Christmas by Abstergo.
