English version：
Tonga
Nation, South Pacific Ocean. Area: 290 sq mi (750 sq km). Population (1997 est.): 101,000. Capital: Nuku'alofa. The people are of Polynesian ancestry. Languages: Tongan, English (both official). Religions: Free Wesleyanism, Roman Catholicism. Currency: pa'anga. Tonga comprises an archipelago of about 169 islands that extends north to south in two parallel chains for about 500 mi (800 km). The eastern islands are low and formed of coral limestone; those in the west are mountainous and of volcanic origin, and four of the western islands have active volcanoes. The country has a developing free-market economy based mainly on agriculture. Chief products include fish, coconuts, sweet potatoes, and bananas. Tourism also is important. Tonga is a constitutional monarchy with one legislative house; the head of state and government is the king, assisted by the privy council. Tonga was inhabited at least 3,000 years ago by people of the Lapita culture. The Tongans developed a stratified social system headed by a paramount ruler whose dominion by the 13th century extended as far as the Hawaiian Islands. The Dutch visited the islands in the 17th century, but effective contact dates from 1773, when Capt. James Cook arrived and named the archipelago the Friendly Islands. The modern kingdom was established during the reign (1845-93) of King George Tupou I. It became a British protectorate in 1900. This was dissolved in 1970, when Tonga, the only ancient kingdom surviving from the pre-European period in Polynesia, achieved complete independence within the Commonwealth.
