The tradition of decorating evergreen trees at Christmas originated in pre-Christian times when people celebrated the winter solstice and promise of spring by decorating with evergreen boughs. Germans brought the Christmas tree tradition to America in the mid-1800s. Today, most American families have large trees during Christmas, many of which are cut from tree farms. Santa Claus traces his origins to the Dutch tradition of Sinter Klaas, and Dutch settlers introduced Santa to American children as a gift-giver who arrives on Christmas Eve. Children leave out cookies and milk for Santa before going to sleep on Christmas Eve.
