I was thinking about that topic today (yeah, scary, isn't it?).
And I just had to let you guys know!
Here in Belgium, we have 2 Santa's!
1 is called
Sinterklaas and "lives" in Spain according to the story, legend, ..., he comes the 6th of decembre.
And another one is called
Kerstman (which is Santa).
If I'm correct, the Dutch colonists took "Sinterklaas" with them to the New World (in Holland, Sinterklaas is on the 5th, but Belgium took the 6th 'cause it's his nameday). But his looks and the story changed over the years, transforming into Santa (and the date changed to Christmas), which we took over not so very long ago.
