Well this is one that's been coming now isn't it? Today we'll go over a wizarding theory for Santa Claus, the implications of it and try and fit a bunch of Santa/Christmas mythos all up in a tiny bow. So let's begin after the break!
Theory 1) There is a Pureblood line of Claus witches and wizards, all of whom have taken over as "santa" at some point.
Assuming children still get gifts from Santa, this would explain it quite well. Furthermore, this gets around a rather obvious problem, that being death. This is a HUGE one... as much as I would like to say that Nickolas Flamel gave St. Nick a philosopher's stone and a large supply of elixir, I also know that more likely than not that stone would have been targeted by someone like Voldemort, though that would have failed for a variety of reasons. But for this, we assume Santa would have a lifespan of approximately 500 years at most and 100 at least, with the idea that wizards have a remarkably long lifespan on average. From this, I would also say that if we are to be completely honest with adhering to mythos, that Santa began being Santa in the year 270. So this would make the likelihood of an immortal Santa more foolish as a result, unless we are to assume that Santa prolonged his life through unicorn blood. Now, as such, the wizards and witches of his line continued his good deeds of protecting children, and giving gifts and protecting muggles, with one *possible* descendant being the wizard with the hopping pot.
From this we have the more "modern" interpretation of Santa that likely ran as tradition through the middle ages to the industrial revolution. These witches and wizards would deliver toys, appearing into houses under the guise of an invisibility cloak before leaving. During this time they also amassed a group of house elves who similarly conducted the work, magically creating and delivering toys to children as well as caring for the Claus line. Into the modern age it can be assumed that there are only a few witches and wizards of the family left, and house elves do most of the work, though they only cater to younger muggles and more forgetful parents, occasionally charming them with a confundus like spell so that they purchasing things that cannot be recreated by magic successfully, like muggle electronics. As such, the Clauses get to relax, while the house elves continue the work of Saint Nicolas. Though this is fairly unlikely, as it would make them the greatest transgressors of the Statute of Secrecy known to mankind.
Theory 2) Santa was a wizard but was an inspiration to an individual that later took the role of santa as it was already established in culture by muggles. This is perhaps cheating, though in hindsight it is more reasonable. Like the above case, this one more likely than not apparated after magically putting muggles to sleep, or under an invisibility cloak, and also likely used House elves, in order to lessen his work load. However, this wizard lived and died during the middle ages. As such, various wizards have occasionally done the work, of Santa, and on occasion breached the statute of secrecy as a result. So while it may have been a bit of a wizarding tradition for some magical families to play Santa by helping muggles a small amount with their magic, it has been for the most part banned, and while muggles often believe that it is in fact a round, red-clad man, it is more or less a creation of their imagination along with the silly idea of flying reindeer with shining noses. The only matter that they did get correct would be the high use of house elves.
