The first first person to bring a Christmas Tree into a house, in the way we know it today, may have been the 16th century German preacher Martin Luther. A story is told that, one night before Christmas, he was walking through the forest and looked up to see the stars shining through the tree branches. It was so beautiful, that he went home and told his children that it reminded him of Jesus, who left the stars of heaven to come to earth at Christmas. Some people say this is the same tree as the 'Riga' tree, but it isn't! The Riga tree originally took place a few decades earlier. Northern Germany and Latvia are neighbors.
Another story says that St. Boniface of Crediton (a village in Devon, UK) left England and travelled to Germany to preach to the pagan German tribes and convert them to Christianity. He is said to have come across a group of pagans about to sacrifice a young boy while worshipping an oak tree. In anger, and to stop the sacrifice, St. Boniface is said to have cut down the oak tree and, to his amazement, a young fir tree sprang up from the roots of the oak tree. St. Boniface took this as a sign of the Christian faith and his followers decorated the tree with candles so that St. Boniface could preach to the pagans at night.
