Use Normal Level of Caution

The Kingdom of Tonga is an archipelago of 176 islands scattered over 270,000 square miles in the South Pacific. The population is about 106,000 people who inhabit only 52 of the islands. Tonga is referred to as the “Friendly Island” so named by James Cook, the British explorer in 1773. In 1845, these islands were united into a Polynesian kingdom. From 1900 to 1970, Tonga was a British protected state but was never colonized. The nation gained full independence in 1970. The first inhabitants were the Polynesians, and this country is the last of the Polynesian kingdoms.

The government is a constitutional monarchy, the only monarchy in the Pacific. The chief of state is a king, and the head of government is a prime minister. Tonga has had a monarchy since the 10th century. Although Tonga has a very conservative, traditional society, the younger population is calling for more political reform leading to a more democratic constitution.

Travellers to Tonga can relax on deserted beaches and enjoy activities such as snorkeling, diving, kayaking, whale watching.
