The tradition of Christmas trees can be traced back to ancient times. In Germany, the tradition of decorating trees with candles and small gifts was first documented in the 16th century, although it is believed to have roots in earlier pagan rituals. By the 19th century, the tradition had spread across Europe and became a popular holiday tradition in the United States as well. Today, the Christmas tree is a beloved symbol of the holiday season, a reminder of the beauty and magic of Christmas.
