Sinterklass and Black Pete, have been a tradition in the Netherlands since the mid-19th century.
The pair started off as characters in Dutch folk stories where Sinterklass and his helper Black Pete, a Spanish moor, came to give gifts to Dutch children.
It's become tradition for people to black-up - wearing curly wigs and bright red lipstick when dressing up as Black Pete or Zwarte Piet as he is known in Dutch - but this has become highly controversial in the Netherlands.
