The Christkind ( = Christ Child) is the traditional Christmas gift bringer in Germany, Austria and Switzerland. On the night of the 24th December the Christkind comes to all children in Germany and brings presents.
It was Martin Luther, the famous German priest and iconic figure of the Protestant Reformation, who promulgated stories about the Christkind as a gift bringer.
In Catholic areas it was adopted as well but later it was gradually replaced by the Weihnachtsmann ( = Father Christmas).
Today, the Weihnachtsmann and the Christkind are both coming for Christmas, but traditionally the Christkind brings all the presents to the kids.
