The German religious reformer Martin Luther (1483-1546) is often credited with starting the Christmas tree custom, but the first appearance of a Tannenbaum was recorded in Germany many years after Luther's death. It was in 1605 in Strasbourg in Alsace, then in Germany, that a chronicler wrote (in old German): "Auff Weihenachten richtett man Dahnnenbäum zu Strasburg in den Stuben auff..." ("At Christmas they set up Christmas trees in their rooms...").
But it is likely that the custom dates back to at least around 1550, since the first of several "Tannenbaum" ballads was circulating in print at that time. By the 19th century this custom had spread across most of Germany and beyond. Several royal Germans are credited with helping extend the tree decorating custom beyond Germany's borders. The Duchess of Orleans (from Mecklenburg) brought it to Paris, while other Germanic royals brought the Christmas tree to England and other European countries. But it was commoners — emigrants from Germany — who brought the Weihnachtsbaum to America.
