Santa Claus, also known as Saint Nicholas, Saint Nick, Kris Kringle, Father Christmas, or simply Santa (Santy in Hiberno-English), is a legendary figure of Western culture who is said to bring gifts to the homes of well-behaved ("good" or "nice") children on Christmas Eve (24 December) and the early morning hours of Christmas Day (25 December).
Santa Claus is generally depicted as a portly, joyous, white-bearded man—sometimes with spectacles—wearing a red coat with white fur collar and cuffs, white fur-cuffed red trousers, and black leather belt and boots and who carries a bag full of gifts for children.
This image became popular in the United States and Canada in the 19th century due to the significant influence of the 1823 poem "A Visit from St. Nicholas" and of caricaturist and political cartoonist Thomas Nast.
This image has been maintained and reinforced through song, radio, television, children's books, films, and advertising.
