how did christmas trees start

Christmas trees are believed to have originated in Germany during the 16th century. The tradition was popularized by Prince Albert of the United Kingdom, who brought the tradition to England in the 1800s. In the United States, Christmas trees became popular after President Calvin Coolidge and his wife placed a tree in the White House in 1923. The tradition has since spread to many countries around the world, and today, the Christmas tree has become a symbol of the holiday season.
