Does anyone know how the christmas tree came to be? Like, why DO we have christmas trees in our houses?

Germany 300 yrs ago. Winter celebration by pagens. Was adopted into the Christmas season in England when the king(1800's) came back to England from Germany with a tree for their Christmas. We inherited it.

The fir tree has a long association with Christianity, it began in Germany almost 1,000 years ago when St Boniface, who converted the German people to Christianity, was said to have come across a group of pagans worshipping an oak tree. In anger, St Boniface is said to have cut down the oak tree and to his amazement a young fir tree sprung up from the roots of the oak tree. St Boniface took this as a sign of the Christian faith. But it was not until the 16th century that fir trees were brought indoors at Christmas time

we have christmas trees because because the color is a sturdy color which is perfect and we use the fur tree because all the needles point towards the heavens to remind us of what christmas is all about.

there are several legends but one say that a monk saw the triangle like tree and he said it looked like the holy trinity ( the father the son and the holy spirit)

I was wondering that myself. =/
