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.
The tree was traditionally decorated with "roses made of colored paper, apples, wafers, tinsel, [and] sweetmeats". Moravian Christians began to illuminate Christmas trees with candles, which were often replaced by Christmas lights after the advent of electrification. Today, there is a wide variety of traditional and modern ornaments, such as garlands, baubles, tinsel, and candy canes. An angel or star might be placed at the top of the tree to represent the Angel Gabriel or the Star of Bethlehem, respectively, from the Nativity. Edible items such as gingerbread, chocolate, and other sweets are also popular and are tied to or hung from the tree's branches with ribbons. The Christmas tree has been historically regarded as a custom of the Lutheran Churches and only in 1982 did the Catholic Church erect the Vatican Christmas Tree.
In the Western Christian tradition, Christmas trees are variously erected on days such as the first day of Advent or even as late as Christmas Eve depending on the country; customs of the same faith hold that the two traditional days when Christmas decorations, such as the Christmas tree, are removed are Twelfth Night and, if they are not taken down on that day, Candlemas, the latter of which ends the Christmas-Epiphany season in some denominations.
The Christmas tree is sometimes compared with the "Yule-tree", especially in discussions of its folkloric origins.
Modern Christmas trees originated during the Renaissance in early modern Germany. Its 16th-century origins are sometimes associated with Protestant Christian reformer Martin Luther, who is said to have first added lighted candles to an evergreen tree. The Christmas tree was first recorded to be used by German Lutherans in the 16th century, with records indicating that a Christmas tree was placed in the Cathedral of Strasbourg in 1539, under the leadership of the Protestant Reformer, Martin Bucer.
