How did a holiday that began in pagan Rome become the centerpiece of the Christian tradition and even a secular global celebration of consumerism across faiths? In Christmas Unwrapped: The History of Christmas, a fascinating 1997 History Channel documentary, historian Harry Smith traces the origins of Christmas and how many of the relative newcomer traditions like candy canes and the Christmas tree came to be. From how cartoonist Thomas Nast defined the look of Santa Claus to how Coca Cola subsequently appropriated it to the profound socioanthropological learnings from Dickens’ classic Christmas Carol, the documentary reveals the rich and surprising history of a holiday that has become a pillar of the modern calendar.

Christmas Unwrapped is available on YouTube in five parts or, for the quality aficionados, as a full-length DVD film from the A&E archives.

The church knew it could not outlaw the pagan traditions of Christmas, so it set out to adopt them. The evergreens traditionally brought inside were soon decorated with apples, symbolizing the Garden of Eden. These apples would eventually become Christmas ornaments.”

[Dickens’] Christmas Carol showed the Victorians what could be the use and the reading of Christmas in a society which was quite pleased with itself in a way but which, nevertheless, had fears about inequality, about materialism, about, perhaps, too rapid change.”

Certainly today, most of the churches revel in the celebrations as completely as do the corporate malls. That’s not a bad thing — it actually goes back to the sources of this kind of holiday, where we recognize that people have deep needs at this time of year to connect with that which is very important, but also to celebrate.”
