History of Santa Claus

Origins
Pre-modern representations of the gift-giver from church history and folklore, notably St Nicholas and Sinterklaas, merged with the British character Father Christmas to create the character known to Britons and Americans as Santa Claus.
In the British colonies of North America and later the United States, British and Dutch versions of the gift-giver merged further. For example, in Washington Irving's History of New York, (1809), Sinterklaas was Americanized into "Santa Claus" (a name first used in the American press in 1773) but lost his bishop’s apparel, and was at first pictured as a thick-bellied Dutch sailor with a pipe in a green winter coat. Irving’s book was a lampoon of the Dutch culture of New York, and much of this portrait is his joking invention.

19th century
In 1821, the book A New-year's present, to the little ones from five to twelve is published in New York. It contains Old Santeclaus, an anonymous poem describing an old man on a reindeer sleigh, bringing presents to children. Some modern ideas of Santa Claus seemingly became canon after the publication of the poem "A Visit From St. Nicholas" (better known today as "The Night Before Christmas") in the Troy, New York, Sentinel on December 23, 1823 anonymously; the poem was later attributed to Clement Clarke Moore. Many of his modern attributes are established in this poem, such as riding in a sleigh that lands on the roof, entering through the chimney, and having a bag full of toys. St. Nick is described as being "chubby and plump, a right jolly old elf" with "a little round belly", that "shook when he laughed like a bowlful of jelly", in spite of which the "miniature sleigh" and "tiny reindeer" still indicate that he is physically diminutive. The reindeer were also named: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder and Blixem (Dunder and Blixem came from the old Dutch words for thunder and lightning, which were later changed to the more German sounding Donner and Blitzen).
As years pass, Santa Claus evolves in popular culture into a large, heavyset person. One of the first artists to define Santa Claus's modern image was Thomas Nast, an American cartoonist of the 19th century. In 1863, a picture of Santa illustrated by Nast appeared in Harper's Weekly.

Thomas Nast immortalized Santa Claus with an illustration for the January 3, 1863 issue of Harper's Weekly.
The story that Santa Claus lives at the North Pole may also have been a Nast creation. His Christmas image in the Harper’s issue dated December 29, 1866 was a collage of engravings titled Santa Claus and His Works, which included the caption "Santa Claussville, N.P." A color collection of Nast's pictures, published in 1869, had a poem also titled "Santa Claus and His Works" by George P. Webster, who wrote that Santa Claus’s home was "near the North Pole, in the ice and snow". The tale had become well known by the 1870s. A boy from Colorado writing to the children's magazine The Nursery in late 1874 said, "If we didn't live so very far from the North Pole, I should ask Santa Claus to bring me a donkey."
The idea of a wife for Santa Claus may have been the creation of American authors, beginning in the mid-1800s. In 1889, the poet Katherine Lee Bates popularized Mrs. Claus in the poem "Goody Santa Claus on a Sleigh Ride".
"Is There a Santa Claus?" was the title of an editorial appearing in the September 21, 1897 edition of the New York Sun. The editorial, which included the famous reply Yes, Virginia, there is a Santa Claus, has become an indelible part of popular Christmas lore in the United States and Canada.

L. Frank Baum's The Life and Adventures of Santa Claus, a 1902 children's book, further popularized Santa Claus. Much of Santa Claus’s mythos was not set in stone at the time, leaving Baum to give his "Neclaus" (Necile’s Little One) a wide variety of immortal support, a home in the Laughing Valley of Hohaho, and ten reindeer—who could not fly, but leapt in enormous, flight-like bounds. Claus's immortality was earned, much like his title ("Santa"), decided by a vote of those naturally immortal. This work also established Claus’s motives: a happy childhood among immortals. When Ak, Master Woodsman of the World, exposes him to the misery and poverty of children in the outside world, Santa strives to find a way to bring joy into the lives of all children, and eventually invents toys as a principal means.
Images of Santa Claus were further popularized through Haddon Sundblom’s depiction of him for The Coca-Cola Company’s Christmas advertising in the 1930s. The popularity of the image spawned urban legends that Santa Claus was invented by The Coca-Cola Company or that Santa wears red and white because they are the colors used to promote the Coca-Cola brand. Historically, Coca-Cola was not the first soft drink company to utilize the modern image of Santa Claus in its advertising – White Rock Beverages had already used a red and white Santa to sell mineral water in 1915 and then in advertisements for its ginger ale in 1923. In fact, Santa Claus had already appeared in red and white on the cover of Puck magazine at the start of the century.

The image of Santa Claus as a benevolent character became reinforced with its association with charity and philanthropy, particularly by organizations such as the Salvation Army. Volunteers dressed as Santa Claus typically became part of fundraising drives to aid needy families at Christmas time.
In some images from the early 20th century, Santa was depicted as personally making his toys by hand in a small workshop like a craftsman. Eventually, the idea emerged that he had numerous elves responsible for making the toys, but the toys were still handmade by each individual elf working in the traditional manner.
The 1956 popular song by George Melachrino, "Mrs. Santa Claus", and the 1963 children's book How Mrs. Santa Claus Saved Christmas, by Phyllis McGinley, helped standardize and establish the character and role of Mrs. Claus in the popular imagination.
Seabury Quinn’s 1948 novel Roads draws from historical legends to tell the story of Santa and the origins of Christmas. Other modern additions to the "story" of Santa include Rudolph the Red-Nosed Reindeer, the 9th and lead reindeer immortalized in a Gene Autry song, written by a Montgomery Ward copywriter.
