where did the custom of the christmas tree come from

The tradition of the Christmas tree dates back to the Middle Ages in Germany. It was believed that evergreen trees represented eternal life and served as a reminder of the birth of Jesus Christ. The practice of decorating the tree with candles and other ornaments was introduced in the 16th century by Protestant Christians in the region. Over time, the tradition spread to other parts of the world, becoming an integral part of Christmas celebrations everywhere.
