Christmas was only introduced into Hawaii in the 18th century, by Missionaries. Before that the Hawaiians had a festival of their own, called Makahiki. This was a time of peace, when no one was allowed to go to war, and the people gave thanks to the gods for food and the fertility of the Land.
Nowadays Christmas is celebrated with lights and a Christmas tree, and a dinner of roast pig. Santa comes, but he is carried in a red canoe pulled by 9 dolphins – and he’s more likely to be wearing a Hawaiian shirt than a red furry jacket.
