A Christmas tree is a fir tree, or an artificial tree that looks like a fir tree, which people put in their houses at Christmas and decorate with coloured lights and ornaments. Evergreen tree, usually decorated with lights and ornaments, to celebrate the Christmas season. The use of evergreen trees, wreaths, and garlands as symbols of eternal life was common among the ancient Egyptians, Chinese, and Hebrews. The Christian symbol can be traced to a German medieval play about Adam and Eve, which included the "paradise tree," hung with apples. The modern, decorated version was widespread among German Lutherans by the 18th century. Brought to North America by German settlers in the 17th century, it had become widespread there by the mid-19th century. It was popularized in 19th-century England by Victoria's consort, the German Prince Albert of Saxe-Coburg
