Santa Claus is regarded as the one who distributes presents to youngsters in many countries. Children frequently write to Santa, requesting gifts, which elves help him produce in his North Pole offices, according to legend. The presents are then delivered by reindeer-drawn sleigh during Christmas Eve and Christmas Day. Children also make gifts for Santa themselves. These can be simple things like cookies or carrots that he may put in his sack, but sometimes they are more extravagant, such as an entire tree with all its branches and leaves. The practice of giving gifts on Christmas Eve has been adopted in some countries where December 24 is celebrated as a holiday. In Germany, Austria, and Switzerland, for example, families exchange gifts at midnight on Christmases when there are no other religious or commercial activities taking place. This custom began in earnest in the 16th century when German merchants would travel to Italy to buy spices and other goods that were not available in Europe elsewhere. Upon their return, they would give something to everyone in their family each night at Christmas time - including servants and slaves. The gift might be given in secret through the door of the house or even left under the Christmas tree! Of all the servants, only the master of the house was allowed to open his present from his master.
