The Christmas tree is a beloved symbol of the holiday season that can be found in homes, advertisements, and decorations worldwide. But have you ever stopped to wonder why we decorate trees for Christmas? While the evergreen tree wasn't associated with Christmas until 1605, the significance of evergreens dates back much further. For example, the ancient worship of the sun god Mithras often included evergreen trees, and Northern Europeans believed that evergreens were especially important around the winter solstice. In the 14th and 15th centuries, pine trees began to be used in "miracle plays" performed at Christmas time across Europe, and the tradition of decorating a Christmas tree spread from there. https://www.ancient-origins.net/history-ancient-traditions/why-do-we-put-christmas-trees-ancient-roots-decorative-tradition-009334
