A Christmas tree is a decorated tree, usually an evergreen conifer, such as a spruce, pine or fir, or an artificial tree of similar appearance, associated with the celebration of Christmas, hence its name, originating in Northern Europe. The custom was developed in medieval Livonia (present-day Estonia and Latvia), and in early modern Germany where Protestant Germans brought decorated trees into their homes. It acquired popularity beyond the Lutheran areas of Germany and the Baltic countries during the second half of the 19th century, at first among the upper classes. The Catholic Church had long resisted this Protestant custom and the Christmas Tree stood for the first time in Vatican in 1982.
