The history of the Christmas tree is actually quite complex, dating back to ancient times when evergreen trees were used to represent the eternal life and rebirth of the seasons. In medieval Germany, people began to decorate evergreen trees with candles, which evolved into the tradition of decorating Christmas trees with lights, ornaments, and gifts that we know today. However, the modern-day Christmas tree we see today was popularized in the 19th century by Queen Victoria's husband, Prince Albert, who brought the tradition from his native Germany to England.
