Were and when does s Santa start?

The modern figure of Santa Claus is based on Saint Nicholas, a 4th-century Greek bishop known for his generosity, particularly towards children. The transformation into the jolly, red-suited character we know today began in the 19th century, influenced by various cultural traditions, including the Dutch Sinterklaas. In the United States, Santa Claus became widely popular in the 1820s and 1830s, especially with the publication of the poem "A Visit from St. Nicholas" in 1823. Santa is typically associated with Christmas Eve, when he is said to deliver gifts to children around the world.
