Sinterklaas is actually the ancestor of Santa Clause. Of course, you will refuse to believe so untill facts are uncovered.
Sinterklaas is originally a bishop donating for the poor, and now he just gives presents to everyone.
Zwarte pieten (black pete's) are afro american people whom work for Sinterklaas. That's from the slavery i think..
When its sinterklaas here, there is a parade of acrobatic pete's and sinterklaas giving stuff to the lil kids and they get all happy.
Our family doesn't like that, so we celebrate Cristmas on the 26th instead.
