Why is the fir tree associated with Christmas?

The fir tree is associated with Christmas primarily due to its evergreen nature, symbolizing eternal life and resilience during winter. Historically, ancient cultures used evergreens in winter celebrations, and this tradition was adopted by Christians to represent the everlasting life offered through Christ. The custom of decorating Christmas trees became popular in the 19th century, further solidifying the fir tree's connection to the holiday. Today, it serves as a central symbol of Christmas festivities around the world.
