years since settlement in late Lapita times. Before the arrival of European explorers in the late 17th and early 18th centuries, Tongans had frequent contacts with their nearest Oceanic neighbours, Fiji and Niue. In the 19th century, with the arrival of Western traders and missionaries, Tongan culture changed, especially in religion. , almost 98% of residents profess Christianity. The people discarded some old beliefs and habits and adopted others. Sport Rugby union Rugby union is the national sport, and the national team (ʻIkale Tahi, or Sea Eagles) has performed quite well on the international stage. Tonga has competed in six Rugby World Cups since 1987. The 2007 and 2011 Rugby World Cups were Tonga's most successful to date, both winning two out of four matches and in a running chance for the quarterfinals. In the 2007 Rugby World Cup, Tonga won its first two matches, against the USA 25–15, and Samoa 19–15. They came very close to upsetting the eventual winners of the 2007 tournament, the South African Springboks, losing 30–25. A defeat by England, 36–20 in their last pool game ended their hopes of making the knockout stages. Nevertheless, by picking up third place in their pool games behind South Africa and England, Tonga earned automatic qualification for the 2011 Rugby World Cup in New Zealand. In Pool A of the 2011 Rugby World Cup, Tonga beat both Japan 31–18 and 5th ranked eventual finalist France 19–14 in the latter pool stages. However, a previous heavy defeat by the All Blacks at the tournament's opener (41–10) and a subsequent tight defeat by Canada (25–20) meant that Tonga lost out to France (who also lost to NZ) for the quarter finals due to 2 bonus points and a points difference of 46. Tonga's best result before 2007 came in 1995, when they beat Côte d'Ivoire 29–11, and 1999 when they beat Italy 28–25 (although with only 14 men they lost heavily to England, 101–10). Tonga perform the Ikale Tahi war dance or Sipi Tau (a form of Kailao) before all their matches. Tonga used to compete in the Pacific Tri-Nations against Samoa and Fiji, which has now been replaced by the World Rugby Pacific Nations Cup, which now involves Japan, Canada, and the United States. At club level, there are the Datec Cup Provincial Championship and the Pacific Rugby Cup. Rugby union is governed by the Tonga Rugby Football Union,
