Santa Claus is the result of cultural crossover and exchange. Historical and folkloric figures like St. Nicholas, Sinterklaas, and Father Christmas combined in various ways over several generations to create the English-speaking world’s most popular personification of Christmas. It was a long, messy journey that involved sailors venerating Saint Nicholas, the Netherlands getting more into the Saint than anyone else in Europe did, New Amsterdam, New York, Washington Irving, and more than a little anonymous poetry.
