Christmas trees have a long history that dates back to ancient times. The tradition of decorating trees for the winter solstice, which is the shortest day of the year, began in Northern Europe. People would gather around a tree and light candles to celebrate the return of longer days and the coming of spring. Over time, the tradition evolved and became associated with Christmas. The first recorded use of a Christmas tree was in Germany in the 16th century, where people would bring evergreens inside their homes to decorate with ornaments and lights.
