North American west coast Indian tribes, such as the Kwakiutl, hold 
potlatch ceremonies where gifts are given and personal property is 
destroyed in order to show financial wealth. Events such as weddings 
and funerals are occasions for these ceremonies. They include 
dancing, food, speeches and gift-giving. Guests who receive gifts are 
then obliged to host potlatches where they try to give even more 
costly gifts to show their own wealth.
