Where did the myth of Santa Claus originate?

The myth of Santa Claus is believed to have originated from Saint Nicholas, a Christian bishop who lived in the fourth century in what is now modern-day Turkey. He was known for his generosity, especially towards children, and over time became known as the patron saint of children. The myth was further popularized in the 19th century when the story of Saint Nicholas was merged with European pagan folklore, and Santa Claus became associated with the giving of gifts during the Christmas season.
