Nauruans descended from Polynesian and Micronesian seafarers who believed in a female deity, Eijebong, and a spirit land, an island called Buitani. Two of the 12 original tribal groups became extinct in the 20th century. Angam Day, held on 26 October, celebrates the recovery of the Nauruan population after the two World Wars and the 1920 influenza epidemic. The displacement of the indigenous culture by colonial and contemporary western influences is significant. Few of the old customs have been preserved, but some forms of traditional music, arts and crafts, and fishing are still practised.
There are no daily news publications on Nauru, although there is one fortnightly publication, Mwinen Ko. There is a state-owned television station, Nauru Television (NTV), which broadcasts programmes from New Zealand and Australia, and a state-owned non-commercial radio station, Radio Nauru, which carries programmes from Radio Australia and the BBC.
Australian rules football is the most popular sport in Nauru; it and weightlifting are considered the country's national sports. There is a football league with eight teams. Other sports popular in Nauru include volleyball, netball, fishing and tennis. Nauru participates in the Commonwealth Games and the Summer Olympic Games
