Patrick Courrielche
In 2015, Courrielche wrote a long form story "St. Nicholas: The Birth Of A Social Weapon" on the origin of Santa Claus and introduced the concept of a "social weapon" - a packaged idea, message, or product that is used by an individual or group to advance their cause. Courrielche argued that New York City elites crafted Santa Claus from St. Nicholas, a widely known patron saint, to stabilize a city plagued by annual misbehavior every December. Santa Claus was then used as a "social weapon" by merchants, craftsman, city rulers, parents, newspapers, and others to benefit their endeavors. The essay was added to the St. Nicholas Center's resource on the Origin of Santa Claus.
Christmas
In 1809, the New-York Historical Society convened and retroactively named "Sancte Claus" the patron saint of Nieuw Amsterdam, the Dutch name for New York City. At his first American appearance in 1810, Santa Claus was drawn in bishops' robes. However, as new artists took over, Santa Claus developed more secular attire. Nast drew a new image of "Santa Claus" annually, beginning in 1863. By the 1880s, Nast's Santa had evolved into the modern vision of the figure, perhaps based on the English figure of Father Christmas. The image was standardized by advertisers in the 1920s and continues through the present day.
