Christmas: A short history

Christmas is celebrated on 25 December and is both a sacred religious holiday and a worldwide cultural and commercial phenomenon.
For two millennia, people around the world have been observing it with traditions and practices that are both religious and secular. Christians celebrate Christmas day as the anniversary of the birth of Jesus. Popular customs include exchanging gifts, decorating Christmas trees, attending church, sharing meals with family and friends and, of course, waiting for Santa Claus to arrive.

How did Christmas start?
The middle of winter has long been a time of celebration around the world. Centuries before the arrival of Jesus, early Europeans celebrated light and birth in the darkest days of winter. Many rejoiced during the winter solstice when the worst of the winter was over and they could look forward to longer days and extended hours of sunlight.
In Scandinavia, the Norse celebrated Yule from 21 December, the winter solstice, through January. In recognition of the return of the sun, fathers and sons would bring home large logs, which they would set on fire. The people would feast until the log burned out, which could take as many as 12 days. The Norse believed that each spark from the fire represented a new pig or calf that would be born during the coming year.
The end of December was a perfect time for celebration in most areas of Europe. At that time of year, most cattle were slaughtered so they would not have to be fed during the winter. For many, it was the only time of year when they had a supply of fresh meat. In addition, most wine and beer made during the year was finally fermented and ready for drinking.
In Germany, people honoured the pagan god Oden during the mid-winter holiday. Germans were terrified of Oden, as they believed he made nocturnal flights through the sky to observe his people, and then decide who would prosper or perish. Because of his presence, many people chose to stay inside.

Saturnalia and Christmas
In Rome, where winters were not as harsh, Saturnalia—a holiday in honour of Saturn, the god of agriculture—was celebrated. Beginning in the week leading up to the winter solstice and continuing for a full month, Saturnalia was a hedonistic time, when food and drink were plentiful and the normal Roman social order was turned upside down.
For a month, enslaved people were given temporary freedom and treated as equals. Businesses and schools were closed so that everyone could participate in the holiday festivities.
Also around the time of the winter solstice, Romans observed Juvenalia, a feast honouring the children of Rome. In addition, members of the upper classes often celebrated the birthday of Mithra, the god of the unconquerable sun, on 25 December. It was believed that Mithra, an infant god, was born of a rock. For some Romans, Mithra’s birthday was the most sacred day of the year.

The birth of Christ
In the early years of Christianity, Easter was the main holiday; the birth of Jesus was not celebrated. In the fourth century, church officials decided to institute the birth of Jesus as a holiday. While the Bible does not mention the date of His birth, some evidence suggests that it may have occurred in the spring. It is commonly believed that the church chose 25 December in an effort to adopt and absorb the traditions of the pagan Saturnalia festival.
In the early 17th century, a wave of religious reform changed the way Christmas was celebrated in Europe. When Oliver Cromwell and his Puritan forces took over England in 1645, they vowed to rid England of decadence and, as part of their effort, cancelled Christmas. By popular demand, Charles II was restored to the throne and, with him, came the return of the popular holiday.
The pilgrims, English separatists that came to America in 1620, were even more orthodox in their Puritan beliefs than Cromwell.
As a result, Christmas was not a holiday in early America. From 1659 to 1681, the celebration of Christmas was actually outlawed in Boston. Anyone exhibiting the Christmas spirit was fined five shillings. By contrast, in the Jamestown settlement, Captain John Smith reported that Christmas was enjoyed by all and passed without incident. – https://www.history.com/
