Santa Claus is a legendary figure who is said to bring gifts to well-behaved children on Christmas Eve. He is often depicted as a jolly man with a white beard, wearing a red suit with white fur trim. The character is based on traditions surrounding Saint Nicholas, a 4th-century Greek bishop known for his generosity. The modern image of Santa Claus has been shaped by various cultures and media over the years. He is commonly associated with a sleigh pulled by reindeer and lives at the North Pole with a group of elves who help him prepare toys for children around the world.
