Learn how the tradition of Christmas tree decorations got started. Many legends surround the beginnings of Christmas tree decorations. One of the most popular such legends proposes that it began with St Boniface, in Germany around the 1st century. St. Boniface happened upon a pagan ritual involving an oak tree, and, enraged, cut it down. A miracle occurred when out of the roots rose a young fir tree. St. Boniface then believed the tree to be a gift from God and as such deserving of adoration.
