how did the christmas tree start

The origins of the Christmas tree can be traced back to ancient times, when evergreens were used to symbolize eternal life and to ward off evil spirits. The tradition of decorating a tree at Christmas became popular in the 16th century, when Martin Luther, a German Protestant theologian, brought the tradition of lighting candles on evergreen trees to his home. The tradition of decorating the tree with lights, ornaments, and tinsel quickly spread throughout Europe and eventually to the United States, where it has become a beloved part of the holiday season.
