How Did Christmas Trees Become Christmas Symbols?
Christmas trees, which are a variety of fir, pine, and spruce trees, are closely linked with the visuals most of us have for Christmas. However, in many ways, the symbol of the Christmas tree seems surprising for the story of Christmas. The development of the Christmas tree as a key symbol begins before Christianity and only long after Christianity established itself in Europe did it become associated with Christmas.
Early Developments Before Christianity
In Northern Hemispheres of Europe, including in Germany, Scandinavia, and other parts of Northern Europe, Yule was traditionally among the most important holidays in the pre-Christian calendar. The Tree of Life is a symbol in many ancient cultures that also as Biblical references. In Northern Hemispheres, much of the landscape would become bleak and short on food during winter. The winter solstice, December 21-22, was celebrate as Yule. This was often a time of feasting and even sacrifice to give thanks to the gods and anticipate renewal of the land as the days begin to get longer and winter ends.
Fir, pine and other evergreen trees were often the only green color present in the landscape, indicating that they had life in them during the depths of winter. The evergreens became symbols of life and renewal and in Old Norse mythology, with evergreens equated with the great mother goddess. Hanging reefs in one's home and other parts of the evergreens was a way to bring luck to the home during a period when death and want were likely.
While Christmas trees are clearly associated with the tree of life from Old Norse mythology, other aspects of Christmas may also link. For instance, Yule trees may have been decorated with lights, particularly candles, to symbolize the stars. Other decorations may have been put around trees in the Old Norse tradition as a way to remember those who died during the year. These decorations could have been personal items or implements that were simply hung around the tree. Gifts placed under or near the Yule trees may have symbolized gifts given to the gods as a token of thanks and offering for blessing in the coming year. The burning of Yule logs was applied to symbolize the life giving force of fire. The idea was that the sun after solstice would begin to gain strength, similar to a sick person gaining strength. As the sun gained strength, then it would renew the land and trees would blossom in the spring, giving life and providing for people.
Associations with Christmas
The date of Christmas chose by the Roman Catholic Church was selected because many societies converting to Christianity had celebrated the solstice and many gods, such as Mithras and others, were born on December 25th. Thus, policies of including pagan traditions with that of the birth of Jesus made conversions relatively easier. With Christmas trees, this likely was also a similar policy as Nordic countries began to convert to Christianity in greater numbers in the late 1st millennium AD. However, Christmas was not universally, even in Nordic countries, applied with a Christmas tree. This might mean that for some time Christmas trees may have had some meaning to people, particularly with their old traditions before they converted, where they remembered people and the renewal of life. However, Christmas trees do not seem to be associated with the home.
During the late Medieval period and early modern period, around the 16th century, we begin to see the use of Christmas trees more frequently or in direct association with Christmas. After the Protestant Reformation, Christmas trees in Germany began to be brought into the home and placed as a way to remember life and renewal along with Christmas. Although nobody knows for sure, why, one possibility is the clergy began to see Christmas trees as heathen practice from pre-Christian traditions, forcing people to bring them to their homes to hide them. Sometimes Martin Luther himself is credited with decorating Christmas trees with candles to symbolize the starts, but this might not be likely given the fact evergreens were decorated already during the Old Norse period and in their traditions.
By 1605, the city of Strasburg was recorded to have Christmas trees decorating places with other associations that we now consider part of the Christmas tradition, such as chocolate covered apples, sweets, and other foods and presents. In the 17th century, many places continued to shun the Christmas tree, seeing it as a symbol of paganism. However, the popularity of the trees never went away. In particular, Christmas was seen as a solemn event by many of the clergy and reveling and feasting associated with Christmas went against this. Perhaps to accommodate a strong popular demand, some of the clergy began associating Christmas trees with Christ and the coming of Jesus to save the world. However, throughout much of the 17th and 18th centuries, only mostly in Germany was Christmas associated with Christmas trees.
