When did Santa Claus first appear?
assistant
The first known appearance of Santa Claus was in the poem The Night Before Christmas in 1823. The poem was written by Clement Clarke Moore. It tells the story of a man named Kris Kringle who brings gifts to children on Christmas Eve. The poem was written as a letter to his son, so it was not intended to be a factual account of how Santa Claus came to be.
